The State of X.Org

An anonymous reader writes "Phoronix has up an article looking at the release of X Server 1.4.1. This maintenance release for X.Org, which the open-source operating systems depend upon for living in a graphically rich world, comes more than 200 days late and it doesn't even clear the BugZilla release blocker bug. A further indication of problems is that the next major release of X.Org was scheduled to be released in February... then May... and now it's missing with no sign of when a release will occur. There are still more than three dozen outstanding bugs. Also, the forthcoming release (X.Org 7.4) will ship with a slimmer set of features than what was initially planned."

Anything else out there?

[CastrTroy]

Is there anything else out there? Why is there such a lack of interest in X.org, when so many other projects depend on it. Most of the big projects have been moving quite quickly, making a lot of headway in the past couple of years. What's holding x.org back?

Re:Anything else out there?

[jeiler]

Probably the complexity of the issues involved, and the ever-expanding environmental requirements X is being written for.

Re:Anything else out there?

[larry bagina]

I agree. I recently discovered the xfree86 project. It seems like a good alternative to x.org.

Re:Anything else out there?

[FudRucker]

RE:"when so many other projects depend on it."

is that a good thing? it is not! i think applications that require an x-window-system should be just agnostic enough to allow for the older alternative to xorg, [eg] http://www.xfree86.org/

Re:Anything else out there?

Uh, a strange thing to say but your posting history seems normal so...

In February 2004, with version 4.4.0, The XFree86 Project adopted a license change that the Free Software Foundation considered GPL incompatible. Most Linux distributions found the potential legal issues unacceptable and made plans to move to a fork from before the license change. At first there were multiple forks, but the X.Org fork soon became the dominant one. Most XFree86 developers who were already annoyed at other issues in the project also moved to X.Org. In short, x.org was xfree86 but that project is practicly dead. Pretty much everyone worth mentioning have migrated from xfree86 to x.org and while x.org may be moving slow, xfree86 has almost stopped dead. Going back there would do little to nothing to bolster X development. Tbe question is rather why there's so little work overall (or so it claims, I don't have enough knowledge to say) since the competition is basicly non-existant.

Wow, you have just answered your question in the same sentence.

Re:Anything else out there?

[CastrTroy]

First, I believe your parent post was a joke. Second of all, the reason most open source projects go stagnant seems to be for a couple reasons. First, the code is an ugly mess, and nobody wants to work on it. Second, internal conflict about where the project is going, so nothing gets done, or every new feature or bug fix becomes a big argument, about how it should be done. Thirdly, very boring project subject matter. The last one seems to be the big killer. There could be a nice open source Outlook/Exchange replacement. It wouldn't be inherently hard to build, but it seems that nobody is interested in doing it. Most of the stuff that gets a lot of attention is the stuff that developers are interested in building.

Re:Anything else out there?

[moosesocks]

I'm guessing that X.Org inherited an absolutely terrifying codebase from xfree86.

Simply getting xfree to compile was a chore, even on the (few and far between) stable releases.

Personally, I'm still unconvinced that X is a particularly "good idea." 15 years later, and the promises of simplicity and compatibility are still unrealized, as every single implementation of the protocol has suffered from numerous problems. Perhaps it would be best to start from scratch, and revise X11 to be a more realistic/practical specification.

Even back in 1994, it was being called the Iran-Contra of user-interfaces.

Re:Anything else out there?

[fireboy1919]

I have a theory.

We're using X as our windowing system because it's what we have, and we need it. But I don't think anybody (or not many people) really *believe* in it.

That is to say, I doubt anybody takes a look at it and says "this is it! This is the way we should do Windowing!" And so the followup, "...and if it this thing worked, then it'd be more awesome."

What people actually say when they start looking at it looks more like this.
"Okay! X.org is a good project! I think maybe I'll contribute my time to it! Hold on...what is this? Why does it have all these features that nobody cares about? Why the nonstandard build system? What's with all the crazy legacy code? This thing is way too complex for me to spend my time on, and what I learn won't transfer to any other work. I'll pick something else."

Re:Anything else out there?

[CastrTroy]

Open source does not work like big business. It doesn't stagnate because there's no competition. It stagnates because people don't want to work on it. There isn't much competition for the Linux Kernel either. That doesn't slow down it's development.

Re:Anything else out there?

[Enleth]

It's a HUGE, and I mean, REALLY HUGE codebase that deals with hell lots of different concepts (graphics, input, networking, ...) that requires a good deal of understanding to modify it properly. Yet, there are less than 30 (!) active developers. That's probably one of the most under-manned Open Source project out there, proportionally to its size. And it's, again, because it's complicated as hell and nothing can be done about this - it's just the way a windowing server has to be.

I've tried to help the project two years ago, I did dome work on input hotplugging and while not much of the code I wrote finally made it to the upstream (Daniel Stone, the man behind the input subsystem, finally decided for a different solution than what I was thinking about - maybe that was a good decision, I'm not the one to judge), I could experience myself how difficult developing X is. Besides skills and experience, you need to be able to keep track of such a big structure mentally, all the time. Not every programmer can do that, even skilled and experienced.

And, no, you can't always abstract everything out and make a nice, clean structure for the code to adhere to. Maybe the X code could be a bit easier to modify, but just a bit. Trying to force that, you would end up with an Xserver counterpart of GNU Hurd, if you know what I mean...

Re:Anything else out there?

[pebcak]

There isn't much competition for the Linux Kernel either. You mean like FreeBSD, OpenBSD, NetBSD, Darwin and OpenSolaris?

Re:Anything else out there?

[Kjella]

Wow, you have just answered your question in the same sentence. The Linux kernel for example, is completely without competing forks that I know of, yet seems to be making good strides. xfree86 was going slow, and even after the x.org revival things again appear to be going slow. With a lot of people focusing on the desktop performance of Linux, why isn't this project interesting? A lot of other projects seem to be progressing nicely even without the competition breathing down their necks. I wonder if part of the reason is that the code is X11 licensed, which is fairly close to BSD so you don't have even LGPL protection of your code. If Stallman is looking for a non-(L)GPL project to replace, maybe he should drop the Hurd and start working on a GPL'd X instead...

Re:Anything else out there?

[Jellybob]

Ahhh, because Windows' display manager is truly amazing.

Now, let me just open an application on another machine, and show it on this one's X server... hmmm... what's that - I need to be running Windows 2008 Server, and have a terminal server license?

How about running multiple display managers, so that I can have more then one person using the machine with seperate monitors and input... no. Thought not.

I could go on, but I think you'll get the point.

Re:Anything else out there?

Glad that was modded as funny. Wow.

X.org should scrap the network transparency cruft. It's never worked well, been a slow performer and is used by a small portion of the user population. It's been supplanted by better tools such as vnc and nx (better as in faster, easier to use, more widely accepted). Scrap that and it would make X.org a lot easier to maintain and use. It doesn't have to implement everything in the protocol specification and that's one thing that could go the way of the dodo.

Re:Anything else out there?

[Rob Riggs]

Seems a bit derogatory to call the BSD, OpenSolaris and Darwin users "smelly hippies". Not all of them are like that.

Re:Anything else out there?

[Enleth]

Geez, people bash on the network transaprency all the time, while it's actually the least of the problems. And it's completely irrelevant when an application connects locally because it happens over a shared-memory IPC (which unix sockets actually is, despite having "sockets" in the name).

I'd say all the old, device-dependent xfree86 code is to blame for most of the needless complexity and while it is being rewritten, it's a slow process that requires more developers than are involved with the project. Working with the new X.org code, while still demanding, wasn't really bad, just required thinking and getting "the bigger picture" well.

Actually, the new code is perfectly capable of dropping network transparency, integration of needless extensions and so on *when it's appropriate*, just take a look at Kdrive. But still too many important things remain in the xfree86 part.

Re:Anything else out there?

[bsDaemon]

oh, sure... blame it on the license... 'cause, you know, all engineers and programmers are more worried about politics than products.

Sheesh.

Admittedly, I know next to nil about the internals of X, however I think that it does its job well for what it was intended. The problem is that home-use of "desktop" linux is NOT what X was intended for.

When it comes to running applications on other, more powerful servers while being able to display the graphics on your workstation, it's tops. I've done it numerous times at school and internships.

In my freshman comp sci class, I'd use PuTTY and a local X server on the windows machine in the lab to access my FreeBSD machines in my dorm room and do my work on them, FROM the lab, in class. (i managed to get the school's admin to pony up static IPs and host names for my machines).

For "desktop linux," I don't see why the system isn't reworked to run off of a frame-buffer and scrap all the X crap -- still keep X for running networked apps.

oh, wait -- that's more or less how OS X is organized, isn't it? Or Windows... you know, the successful "desktop" operating systems -- not the systems that were designed for collaborative efforts in scientific and research environments.

Yes, I am simultaneously defending the UNIX way, and saying that it doesn't really address the problems that "normal" home users have.

It's worked for me, since I was 12 or 13 when FreeBSD 2.2.8 hit my machine, but I never expected anything other than what I was getting and so I got just what I wanted.

or new developers to tackle bite-sized portions of the stack without being overwhelmed. Anyone care to comment on whether this was done?

Yes, it was - hence rapid development things like mpx, xrandr, xrender, composite xinput 2.0 and so forth. Have people really forgotten so fast that a couple of years ago linux /didn't do/ all those gee-whiz window explodey effects?

Really, the /. story is inflammatory flamebait. Loads of pretty cool new stuff has appeared recently in X.org. Actually, IMO that's more likely why the release schedule slipped - stuff like MPX is very cool but represents very major changes.

Emacs' release schedule recently slipped too - but it was because they're merging ECB and window groups into Emacs 23, not because emacs devel has stopped!

Re:Anything else out there?

I remember when X.org started one of the things they promised was that the code base would be modularized allowing for new developers to tackle bite-sized portions of the stack without being overwhelmed.

Re:Anything else out there?

[Undead NDR]

Open source does not work like big business. It doesn't stagnate because there's no competition.

Not entirely true, IMO. Even though no money is directly involved, a team of open-source developers will still want their project to be successful over competing projects as a matter of personal pride and potential business opportunities.

If there's no competition, they have one less motivation to keep up work.

Re:Anything else out there?

[drinkypoo]

There's no reason the graphics system and drivers have to be anywhere close to the same project as the window manager.

They aren't.

Well, the drivers are. But obviously at this stage they DO have to be coupled to the server for a variety of reasons, not least that no one else wants to take over.

But let's face it, twm hasn't had any major work in a long time, and the window managers we all use on a daily basis are nowhere near the X.Org codebase.

Do we really need network transparency?

Yes, we do need network transparency. I use it all the time. It's a major feature. Keep your hands off my network transparency!

Re:Anything else out there?

[kripkenstein]

In addition to those factors, I'd say the problem is also a lack of interest.

On the one hand we have things like GNOME and KDE, Firefox, Blender, etc. etc. - software that the user knows by name and interacts with directly. People happily join such projects and contribute code to them.

On the other hand you have software that the typical user might not not even know exists, like the Linux kernel. However, for geeks the kernel is perhaps the pinnacle of programming, and furthermore by lucky coincidence (or unhappy, if you are GNU) the name of the kernel has become synonymous with the entire OS, making it high-profile just like the more obvious software projects mentioned in the previous paragraph.

Whereas the X server is somewhere in the middle. It isn't well known, even geeks might not know exactly what it does (i.e., where the separation is between X, the window manager, and so forth), and for some reason it lacks the 'coolness' factor of the Linux kernel.

All of this is unjustified, and a shame. Perhaps more stories on Slashdot like this one will raise awareness? Maybe we should also motivate people, by e.g. telling them that hacking X is even harder than hacking the kernel ;)

[...]
For "desktop linux," I don't see why the system isn't reworked to run off of a frame-buffer and scrap all the X crap -- still keep X for running networked apps. X uses multiple communications channels. There's TCP and DECnet, used for apps running on a different machine than the display server, and there's Unix pipes, which provide much higher throughput for local apps. But Unix pipes are nearly legacy now, because most servers also support MIT-SHM (the MIT Shared Memory extension), which lets an app have direct access to the X server's graphics buffers, and GLX (the OpenGL extension), used for running 3D graphics over a network. Finally, there's VirtualGL, which is a layer that can be used on top of either X11 or VNC. (See http://en.wikipedia.org/wiki/VirtualGL for more info.)

X11 already provides desktop Linux with you need to run high performance graphics.

Re:Anything else out there?

[Hatta]

When displaying to a local server X uses unix domain sockets. Those are very fast, and they're caching friendly, so they compare well with other forms of inter-process communication like shared memory. If you have some evidence that network transparency is any kind of a bottleneck, I'd like to see it, but no one has been able to produce such numbers as far as I've seen.

Don't optimize before you've proven where the bottleneck is.

Re:Anything else out there?

[Wdomburg]

Considering Linux the kernel targets everything from the embedded space to the mainframe, I'd say they are.

If you're talking about the desktop space, there's really little to nothing that a user interacts with that wouldn't run on any of those platforms. Linux just happens to have the most traction (which has a multiplying effect since it encourages vendor support and attracts new developers).

Re:Anything else out there?

[Novus]

Yes and no. Most of the core technology is GPL, but the front-end stuff, and therefore the actual client and server packages, are freeware or commercial. FreeNX is a fully-GPL fork.

Re:Anything else out there?

[kosibar]

Okay, so here's an idea...

We should revive XFree86. To start, we should generate a list of features for the next release. We'll spread some rumors about what we're doing, let the world see how hard we're working on it.

This should get some attention from /. and other sites to get people involved but we'll freeze the code and not allow any new developers/submissions on the project. Frustrated, they'll go over to X.Org to try to work for the competition.

Now for phase II. About this time next year we announce a release date, delay it a few times, then release it about two years from now. Make it a big deal. Major release. Get everybody talking about it.

For the release we'll drop all of the major new features on the list. We'll fix a bug or two, something major like a spelling error in a log report. Of course, we'll add a few new bugs. We could drop support for some hardware. For new features we could change a few things in the conf file. Instead of "Section" you now have to use "Block". We could totally change the format of the ModeLine to something totally crazy (crazier?)

If this follows the corporate model we have today it should drive major innovation and more frequent releases from X.Org, though our XFree86 project would unfortunately take away most of X.Org's market share.

Open source projects would probably earn the respect of more businesses and government agencies if it would just follow these common sense models from the corporate world.

Re:Anything else out there?

[peragrin]

that was the point of the fork though. Xfree86 developers moved slowly before X.org was formed, and wouldn't introduce changes like 3D accelerated desktop, period.

Developers where complaining about xfree86 for years before the fork, When the license changed it was just enough to push the fork. X.org began a long boring process of breaking X into smaller modules which will accelerate overall development. The problem is that process is still on going, and will take a few more years before any major upgrades can take place.

Think about the Mozilla project. They spent years cleaning out the core codebase and upgrading the core gecko engine from Netscape before they even had a decent beta. X.org is doing the same to something far larger, and uglier.

Re:Anything else out there?

[Luyseyal]

It isn't well known, even geeks might not know exactly what it does (i.e., where the separation is between X, the window manager, and so forth), and for some reason it lacks the 'coolness' factor of the Linux kernel.

Oh, what sad times are these when even persons calling themselves geeks do not know the difference between X, the window manager, windowing toolkits, etc. There is a pestilence upon this land. Nothing is sacred. Even those who arrange and design shrubberies are under considerable economic stress at this period in history.

Re:Anything else out there?

[0xABADC0DA]

I would like to contribute to the X, but mostly what stops me is that the code is written for the 80s. Lots of internals are using macros and bit values and optimization hacks, and directly 'speaking' X11 protocol. The code is disorganized, with files in weird locations and with two-letter names. I'm not blaming the developers, because in the 80s this is what had to be done. And they are making huge progress making it modular and organizing the code. But it's still not an attractive codebase to dig into.

Then, once you have decided to work on it and have fully absorbed X11 protocol into your being, you basically need a vmware license in order to develop. It's almost as hard to try out the changes you made as it is for kernel developers... slightly easier, especially for debugging, but you still need to either shut down everything you are doing to run a new build or have multiple development systems.

So basically it is a really step hill to overcome just to start developing X. Perhaps steeper since the kernel at least has excellent, 'simple', modular code to work with.

Re:Anything else out there?

[larry bagina]

Yep. We recently swapped our production servers (from gentoo) to FreeBSD. Most of the senior linux admins quit in protest (they spent all day recompiling kde and testing themes so no big loss). Withe FreeBSD, we've seen better performance under heavy loads, but more importantly, that overwhelming stench of rancid pizza and dorito farts is gone.

Re:Anything else out there?

[cerelib]

I have done and do this quite often. The killer is latency, not bandwidth. Running apps from within my company's network is nearly as fast as running them on my desktop. If I want to run from my university a few miles away, it feels a bit sluggish. If you try to run from across the country, you will feel the latency. If you are using satellite, you will probably feel the latency. So, it does have its uses, but a user needs to understand the limitations as well.

Re:Anything else out there?

Re:Anything else out there?

[nguy]

A lot of Mac's success *IS* because its gui framework.

The GUI framework on the Mac is Cocoa. The equivalent of Cocoa is Gnome (or KDE). The underlying display server, the equivalent of X11, is Quartz.

it appears to be managed in frame buffer

But it isn't. OS X has the same client/server display architecture as a Gnome desktop.

with custom rom that makes sure you never see bios info -- just pretty pictures.

What you see on OS X is that the boot loader quickly throws up a gray screen to keep you from seeing the boot loader text; the text itself is still there. If you like, you can boot OS X completely in text mode, just like a Linux system.

the removal of large swaths of abstraction make it load and "talk" faster.

The OS X display server has at least as many layers of abstraction as X11. It is not intrinsically faster than X11 (if anything, it's slower). Mostly what you perceive as speed on OS X is massive amounts of backing store.

the use of pdf rendering

OS X doesn't really use PDF rendering.

and enforcing policy rather than just providing tools means that things like cut and paste work from app to app, every app.

I own several Macs. The notion that "cut and paste work from app to app, every app" is laughable, and Apple couldn't enforce that if they tried.

Furthermore, if anything, policy is determined by the GUI framework, not the display server.

That is the sort of thing that X fails on for the casual or home user.

Whatever problems you think the Linux desktop may have, they have nothing to do with X11; consistency and policy is determined by the desktop environment, not the display server.

I can just set up a simple script (or use the dialogs if that's your bag) that always does the right thing when I hit the screen switch button.

Re:Anything else out there?

[ThePhilips]

My personal bet is that X is overly complicated.

E.g. it takes 20-30 minutes to start doing something with Linux kernel. Entry bar is set low - many people like to participate. Needless to mention that to compile (properly configured) Linux kernel (with subset of drivers and features you really need) only few minutes. There are piles and piles of documentation and forums where you can find anything.

E.g. KDE + Qt. To compile KDE - you might need days. Or just grab precompiled binary packages. But after that you can in 5 minutes create something useful and interesting. Documentation is near perfect and complete. Also reading source code is quite easy, since most of the code is human readable.

But X is different beast. Even compiling it is challenge on itself. There is literally no documentation on its innards. There is no "Hello World" for X. There are bunch of example modules which you need to spend hours after hours to only understand where they plug into the all X mess.

I'd say main X problem is its strive to be cool and sit on all chairs. I'd say they need to scale down the project and split it into smaller independent pieces. Forget large releases (installing apt-get would help! kidding). The smaller sub-projects would have more chances attracting people, since (at least theoretically) then entry barrier would be lower.

Re:Anything else out there?

[0xABADC0DA]

Personally, I'm still unconvinced that X is a particularly "good idea." 15 years later, and the promises of simplicity and compatibility are still unrealized, as every single implementation of the protocol has suffered from numerous problems. Perhaps it would be best to start from scratch, and revise X11 to be a more realistic/practical specification. The main problem I think is that X is written in C. Originally the X server did graphics itself, scan converting lines and such, so it had to be in C (and there weren't many real alternatives then). Now all it really does is manage a lot of information -- and C is a really really bad language for managing lots of information. Even a simple desktop has over a thousand "windows" that all have position, change listeners, and other properties. Then there are all the bitmaps, pens, backing stores, repaint regions, etc. Events, queues, messages.

The X server should be mostly scrapped and rewritten in Java. Java is a language that is suited for managing information like that, while still being high-performance (enough). The server could be rewritten in C++, but C++ is messy and is a complicated and archaic language at this point anyway.

Take a look at for instance weirdx which basically one person did. It handles most of the core functions of X and plenty fast (of course it is incomplete since it is one person's hobby). Or see Sun's Project Looking Glass, an opengl X server written in Java -- that was also written in one guy's spare time. With more development on these they could be real competitors to X.org while being more approachable, and I'll bet faster than the C code.

Re:Anything else out there?

[Abcd1234]

Which is why a) no one ever writes directly against Xlib, and b) Xlib is being replaced by Xcb.

Re:Anything else out there?

[Randle_Revar]

If you mean "take out the tcp/ip part", that wouldn't really change anything. If you mean "take out everything that enables networking" that would be a lot of work, and it still wouldn't get you very much. The hard part of maintaining and working on X internals doesn't really come from the network transparency stuff itself.

Now, if you have to deal with xlib for the X protocol, that can be a pain. But that is why XCB (X C Bindings) was invented.

XCB is apparently very nice to work with, and it has "a small footprint, latency hiding, direct access to the protocol, improved threading support, and extensibility". The most recent distros are using XCB/xlib which uses XCB internal, while allowing xlib apps to function without changing anything. When XCB is standard in enough installed systems, apps and toolkits can begin migrating to native XCB. When the Awesome window manager 3.0 comes out, it will be the first WM to use XCB directly.

As for NX, it is really just compresses the X protocol and encrypts it. If you remove X network transparency, NX is useless. I, and I suspect many *nix admins, vastly prefer NX or X over SSH to VNC, RDP, etc (of course plain ssh probably gets used more than all of those put together on *nix).

Re:Anything else out there?

[erudified]

I'd say all the old, device-dependent xfree86 code is to blame for most of the needless complexity

I agree 100%. I'm not an Xorg developer, but recently I put together a hackintosh and started playing with developing a framebuffer driver for my old Radeon X1400 Mobility. Comparing IOPCIDevice and IOFramebuffer with libpciaccess is night and day.

Firstly, and I don't really mean to be insulting here, but libpciaccess just sucks. It's a step in the right direction, but comparing this with IOPCIDevice is... well, it just doesn't speak well for the open source world. The API documentation tells the story pretty well. This is a stable API that hasn't changed in a good, long while. And why should it? It does everything you need to do to speak with a PCI device, it's easy to understand, and it works.

Secondly, IOFramebuffer. Again, an API that hasn't changed in a good, long while. It's simple, it publishes a framebuffer and lets everyone go on with their business. It completely separates modesetting and the publishing of a framebuffer from acceleration. This is a huge win.

The IOAccelerator header docs aren't published, but given what we've seen so far, we can infer that it's clean, it hasn't changed in a while, and it works. Why can't we have this sort of fundamental cleanliness accepted in the open source world? I feel like this stuff is about a decade ahead of Linux.

And the X protocol itself? Well, it sucks. I have an 802.11g network here at home, and X sessions are completely unusable over it. This is failure. It is abject, complete, utter failure. We're not talking long distances, we're talking both machines and the router all within 20 feet of each other. With compression, without compression, over ssh, not over ssh: FAIL. This is a common modern use case, gentlemen. If the X protocol fails it on a wireless home network, what the fuck is the point of it? Xlib is an anachronism. It is the single shittiest piece of the GUI development stack on Linux, and there's plenty of fail to go around. Ditch this bullshit, I beg you.

Follow the Apple model, provide a simple VESA modesetting driver and a software renderer and ship the fucking thing. Why has no one looked at the preeminent operating system for graphics professionals an said "hey, maybe these guys know what the hell they're doing? and omg, some of this stuff seems to be open source!" - I'll tell you why, not invented here syndrome. Those macfaggots created it and fuck them, we'll show 'em good with our 1980s network protocol and 600 pages of completely unreadable API documentation (joke's on you, it's out of date anyways!). How's that working out?

This unholy mess needs to be fixed if Linux is going to stand any real chance on the desktop.

I say we nuke it from orbit. It's the only way to be sure.

P.S., I know this seems critical but I hope it's interpreted as constructive. In case it isn't, props to the Xegl crew, David Airlied, and the whole RadeonHD team. You guys made a driver for a wide range of modern hardware that basically anyone (if I can, you can) can read through and get an understanding of pretty easily. No simple feat. A lot of truy extraordinary developers have contributed a lot to X, and I salute their efforts and could never hope to be half the programmer that they are, but I recognize that there's only so much lipstick you can put on this pig.

Ahah... ahaha. No. The Linux kernel is very poorly documented. Your comment should read "there's *out of date* and *useless* documentation, scattered around the internet where you will never find it."

Unless you consider the source itself documentation... which is hard to argue for a source tree that is millions of lines.

Re:Anything else out there?

[Anonymous Coward]

My personal bet is that X is overly complicated. Overly complicated? Or just inherently complicated? A graphics driver (which is essentially what X is) has to interact with the kernel via an interface defined by the kernel, with hardware, and with the window manager. The only one of those that it can define is the relationship with the window manager.

By contrast, the linux kernel can define both its driver interface (how it interacts with hardware) and its API (how software interacts with it). The kernel pushes complexity into the driver space. X is stuck managing that complexity.

X also suffers from having a complicated function. Managing graphical relations is computationally intensive and difficult. That's why the GPU is separate from the CPU -- to allow for specialization of these complex functions.

A third problem is that X is more general purpose than many drivers. It would be easier if it only had to work with one monitor and graphics card, but the reality is that it is expected to work with all of them. This is also true of the kernel, but the kernel has greater ability to push the heavy lifting into the hardware's driver than X does.

Finally, I think that one of the biggest advantages that the kernel has over X is that it is adjacent to more things. X lies between the kernel, the graphics hardware, and the window manager. Generally, X uses the kernel rather than the other way around. Therefore, it's only people that are working on graphics hardware and the window manager who are interacting with X and therefore likely to find something that they want to change. By contrast, any program might make a kernel call.

Similarly, KDE/Qt and Gnome are accessed directly by many programs. Programs should be accessing X through the window manager.

All that said, you are probably correct about X needing to split itself into smaller, more elegantly abstracted pieces. However, even if X does that, it is still likely that it will be under documented with relatively less participation than other projects. While fundamental, it's simply not adjacent to enough other software to recruit easily. Without recruits, who is going to write the documentation and tutorials needed to gather more recruits?

Of course, we may simply be confusing words here. You may be using complicated to refer to what I would call inelegant or non-modular.

Is this the funny part? Java's reliance on garbage collection makes it perform too poorly for graphics. I like Java, but not for something like this. The only funny part is how stupid the mods on slashdot are. Starting openoffice writer did four garbage collections for a total of 0.03 seconds with a not even optimized server. Garbage collection is not a problem, and if you had read the post the X server hasn't done graphics for a long time -- it's just a middleman between the applications and hardware acceleration.

Have you guys ever actually tried Looking Glass? It doesn't stutter. There is no reason not to use Java for something like this except prejudice.

Re:Anything else out there?

Oh, so by "X needs to fork", you meant "I have a brilliant idea that the experienced software developers working on X.org have surely not thought of, and all I need is to convince someone else to do it, and I'm going to respond to any criticism of my brilliant ideas with the insinuation that other people should do this work for me."

I have other projects to refactor, thank you. I'll leave the X.org developers to decide how best to approach their code.

Re:Anything else out there?

[Anonymuous Coward]

Then, once you have decided to work on it and have fully absorbed X11 protocol into your being, you basically need a vmware license in order to develop. It's almost as hard to try out the changes you made as it is for kernel developers

You don't need any vmware license.

You can safely run more instances of the Xorg server on linux - just start on another screen (ex. Xorg :1). It's just that easy - the server will run in another virtual console. If you know you made changes that could lock up your screen/keyboard, you could conveniently schedule an at(1) process to kill it after 2 minutes (or ssh into the box from another machine).

And if your messing with video card driver code, then again vmware won't be of any use. Unless you're working on the special driver for the vmware virtual video card itself.

And finally, at least for debugging and testing purposes, qemu (which is free) works just as well as vmware.

X isn't sinking.

A better comparison is: do you keep sailing a ship that floats just fine, but is butt-ugly, slightly slow, has some odd quirks, and is missing some nice features found in the most modern ships, or do you build a new one? If you have plenty of resources at your disposal, you might as well build a new one. If you're resource-constrained, however, you better stick with what you have and just continue to patch it up.

While I was long-time subscriber to xorg-devel and other related MLs, every holy war fought there was nailing X coffin slowly but surely. Do they still sing "network transparency out of the box" mantra every time someone suggests changing architecture ?

Re:Finally, developers' ignorance and childish

[Anonymous Coward]

Do they still sing "network transparency out of the box" mantra every time someone suggests changing architecture ? That's the complaint you're going to go with? Seriously? Something that degrades gracefully into the ideal solution (shared mem and unix sockets) for a local-only graphics server?

There's a LOT wrong with X.org right now, even mentioned in TFS. I personally wish they would put a lot more work into the transition to evdev and HAL, so we can get rid of xorg.conf and finally make strides to being as user friendly as "the other" OSes.

But network transparency? You're fighting the wrong battles here.

Re:Finally, developers' ignorance and childish

[Anonymous Coward]

Internally, X11 running in local mode works the same way as Apple's window server - using shared memory and local sockets. Hell, even Windows Vista works this way (except using Windows IPC mechanisms instead of Unix ones).

Everyone who suggests changing the architecture of X by removing network transparency is arguing from a position of ignorance. There isn't a faster mechanism for doing a GUI server without either building the windows server into each app (allowing only one app at a time), or building the window server into the kernel (bad idea).

Re:Finally, developers' ignorance and childish

[kaiman]

But network transparency? You're fighting the wrong battles here. That is so true. Using Macs myself since a couple years.

Network transparency is *the* feature of X.

Re:Finally, developers' ignorance and childish

[diegocgteleline.es]

Internally, X11 running in local mode works the same way as Apple's window server - using shared memory and local sockets.

It doesn't uses shared memory, I think. There's a "shared memory" extension, but there's not a "shared memory transport" for the X11 protocol. Sun's propietary server has a shared memory transport, and it was said that they'd opensource and port it for X.org, but so far nothing has happened. It'd be an interesting thing to have, i think - today, when an application wants to display a image in the server it must send the whole image to the server (the protocol is network-oriented so it can't send a "reference" like a file, it has to send the whole data of the image). If the client app keeps the image in its memory after sending it to the server, the image is using 2x its memory size (one in the server, one in the client). With a shared memory transport, client and server could shared the memory that the image is using. Or so I've heard.

Re:Finally, developers' ignorance and childish

[siride]

No windowing system has anything resembling widgets on the server-side. It's all done in client-side libraries, where that kind of stuff belongs. The server-exposed interface just provides the mechanisms needed for implementing widgets. That part is fine and doesn't need to change.

As for the protocol, only a few parts are actually poorly designed. Grabs need to be reworked as they can result in subtle race conditions and lock-ups. There's a lot of old cruft that nobody uses that could go away, but isn't really causing a problem by remaining in the protocol. The main historical problem was Xlib, which did a lot of stupid things with the protocol, resulting in reduced performance, especially over the network. XCB fixes that, although no toolkits have been ported to pure XCB yet (and it may be a while).

Ultimately what's going to be happening is the move towards Composite/EXA, OpenGL and DRI(2) for everything, which should negate a lot of the existing problems with X's rendering infrastructure. Again, the lack of manpower is going to prevent these projects from making much forward progress.

Re:Finally, developers' ignorance and childish

[Anonymous Coward]

local sockets *are* implemented as shared memory by most (all?) operating systems. The X-SHM extension you're referring to, has nothing to do with how the operating system implements local sockets; instead it allows applications to make use of shared-memory even when client and server are not on the same machine.

Re:Finally, developers' ignorance and childish

[spitzak]

You are correct that X wire protocol is ugly. However this is NOT a reason to abandon network transparency. If you removed network transparency you would still have an ugly protocol, just communicated in shared memory instead. But if instead you fixed the protocol while keeping network transparency, you would have the good protocol PLUS network transparency.

The fact that you even remotely consider communicating larger objects than drawing commands to the server, such as widgets, is proof that you have never even thought seriously about how these things are programmed. It will not work, it would be unbelievably complex. In X this is where the horror of the ICCCM window manager hints and protocol come from (basically it is an attempt to put a complex "window+frame" object over the api). Windows and OSX do not do this at all, all communication that leaves the app's local address space is pretty low-level drawing commands.

Client-side fonts are done by sending the bitmaps of the fonts over. It is a huge win, because no longer is there a "font object" that is attempted to be communicated. It is exactly the OPPOSITE of your proposal.

Re:Finally, developers' ignorance and childish

[Wdomburg]

Erm, no. X-SHM came from MIT, not Sun, and is a mechanism for bitmaps on the same machine to be stored in shared memory segments.

There have been several proprietary shared memory transports added by vendors over the years, including Sun, so the poster is correct. And once upon a time Precision Insight wrote an implementation for XFree86 as well.

However the conclusion after benchmarking various operations was that there was little to no benefit over the unix domain socket transport since it doesn't speed up render-bound operations at all the most significant transport-bound operations are already optimized using the SHM extension. Though performance was improved slightly on some hardware the recommendation after initial implementation and optimization was to abandon the effort.

What's the problem?

[larry bagina]

It's Open Source -- unlike proprietary software, we're not at the mercy of a company to dictate the release schedule or fix bugs if they get around to it. If bugs aren't fixed, it's because we failed to fix them.

Re:What's the problem?

[cjjjer]

Maybe not at the mercy of a company, but a team of core developers that don't want to do it any more. Now tell me which is worse?

And don't try and throw the "oh we can do it ourselves crap". The issue here is maybe the casual developer has contributed are you saying that this casual developer now has to work on it full time so the project can move forward?

Not likely to happen.

One of the problems facing OSS is the people who move it forward are the ones who live, breath and feel passionately about the project (99% of the time the core developers), take away those people away and the project usually dies no matter how popular it is.

Asked about probable fix timeframe/schedule of this bug on lkml , most responses were in form "it's free, we're doing it in our spare time, so don't ask when" . Then I tried to determine if any amount of money can help, asked developers if they can pricetag bugfix/patch and how to pay them - there was no definite answer at all. Children , playing in their sandpit and bearing no responsibility for their code at all, unmotivated and unmotivateable by anything but most basic urges .

Yeah, doesn't it suck when people are safe and happy enough that they can't be bribed, and they just sit around labouring to use their talents according to their own interests and desires and sharing the things they create?

Re:Phoronix will pay to fix X

[The Ultimate Fartkno]

Bribery? I completely fail to see your logic here.

BattleCat needs to have a bug fixed. He approaches coders who, for free and in their spare time, code.

"Hey there, coderman. I see that you do this sort of thing for free and for fun, but what would you say to doing that coding thing that you love to do, hitting this one bug that I really need fixed, and ending up with all the satisfaction that you normally get from your work and a shiny nickel on top of it?"

"ZOMGBRIBERYYOUCALLOUSBASTARD!"

Really? Is that what you call bribery? Where I come from, bribery entails a breach of ethics. All BattleCat wanted was to add a little icing to the job that people were already doing for free in an effort to have something fixed that was a priority for him. That's about as straight-up, ethical, and non-bribery a way to get things done as I can imagine.

Re:Phoronix will pay to fix X

[tinkerghost]

If someone is going to pursue a task because the task is its own reward, and you entice them to pursue a different task that isn't its own reward by offering them money, that's bribery.

'I will pay you to make my problem your top priority' is among the many things that people are saying about how a FOSS economy is supposed to work. Paying people to do work for you that you can't/don't want to do dates back to at least the bronze age, and probably farther. I would go so far as to say that it's one of the cornerstones of civilization.

I think the OP went about it the perfect way:

1. Identified his problem
2. Identified the existing bug
3. Identified the existing timeframe on fixing the bug (there was none)
4. Offered some financial support to the project as a whole in order to get his problem addressed as a priority.

Essentially, he tried to hire a programmer/programmers to fix his problem from the pool of programmers who know the code the best - the active developers. Anyone with a serious intent to fix a software problem is going to go the same route - grabbing a coder off the street isn't going to be nearly as productive as grabbing the guy who wrote it in the first place.

Re:Phoronix will pay to fix X

[db32]

Bribery, a form of pecuniary corruption, is an act usually implying money or gift given that alters the behaviour of the recipient in ways not consistent with the duties of that person or in breach of law.

Your problem here is fixing bugs in X is consistent with the duties of that person. In fact, you could even go so far as to saying writing code is consistent with the duties of that person.

What you are attempting to call bribery is what damn near everyone else in the world calls a job offer. He was attempting to hire someone, not to bribe them. If that was indeed bribery the job market would be a very scary place where employers could be convicted for making job offers for perfectly legitimate work.

Sounds good to me. Working for money is the antithesis of integrity, and the social systems that make it necessary are constructed for the purpose of overcoming the integrity of the individual so they can be put to use like some inert tool.

I've been using Ubuntu for 4 years now and it's pretty much shielded me from any lack of quality in the releases. Probably if I spent more (unnecessary) time under the hood it would expose issues but I've been living in a very blind 'trust Ubuntu' atmosphere where things pretty much just work (ok, lets not mention the recent key generation problem :)

On the one hand, this is why I dislike Ubuntu. It doesn't require that the user learn much about how the system works. They plop the CD in the tray and it takes care of them, breeding a generation of Linux users that barely have an idea how to file a proper bug report.

On the other hand, I realize that Ubuntu is a good thing for Linux adoption because Linux needs a critical mass of people using it before it can start making inroads into the home and gaming markets. That critical mass is much larger than the number of people interested in --funroll-loops, so a system that's plug-and-play is important.

Aside from Keith Packard and Dave Airlie, and maybe one or two others, how many paid full-time X developers are there? Watching the mailing list, it seems like there's a couple of volunteers, some people who submit the occasional patch but otherwise work on Qt, or GNOME or whatever, and then the core listed above. I think there just isn't enough manpower right now and the distros, instead of fixing that problem, just maintain their own patchsets and do a "good enough" job to make X work smoothly for their releases, and leave it at that. Clearly, nobody wants to make X a priority and it shows. The Wiki is almost never up to date, it's nigh on impossible to build a working X system from git, even with the couple of half-arsed build scripts available from the mailing list (for my part, I have never been able to get it to build completely, and not for lack of trying or ability). The mailing list is full of academic arguments over color specs and other pointless things, or people asking for help. There used to be a lot of discussion on how to improve X and also, how to get things done. That no longer happens. What the distros and Linux companies need to do is get more people working directly on X and get serious about making X a serious project. It's not just some option piece of software that nobody has to care about. It's only one of the most important aspects of desktop Linux. And it just makes no sense to me that no distros are really spearheading X development. If they don't take the time to make this an issue, X will continue to atrophy, further limiting Linux's potential in the market.

I am a huge Linux advocate, but ignorant people blaming missed release cycles on the "community" is just stupid. There are developers and users, and if the developers want to go open source they damn well need to accept that fact. Just as the user accepts that their open source project of choice may not be updated (sounds familiar huh). We're in the same boat, but don't for a second blame users for developers short comings, open source or not.

[Chemisor]

Well, excuuuse me! Blame the community. I would blame the code instead. I happen to be one of those few people who actually wanted to contribute something. Specifically, there was this bug where the server would crash after a VT switch, so I thought I'd take a look. Have you seen the X.Org tree? It's not just huge. It's unreadable. I honestly didn't even know where to start. Documentation was minimal. If you wanted to trace one of your Xlib calls, you wouldn't be able to. There are modules, but they don't seem to have any clear purpose. There are libraries that are wrappers around something which is a wrapper around something else. Try and find the real code! I dare you! Even just building the damn thing is a major ordeal. With the current XOrg tree from git, I can't do it at all. Yes, that's right: I can't even compile it, and that ought to be the simplest thing you can do with a project. You want to know why I'm not helping the XOrg project? Because it's a pile of steaming crap, that's why, and I have better things to do with my time than trying to build a windowed skyscraper out of it.

How X got to where it is

[jonsmirl]

Three main trends got X to where it is.

1) Proprietary hardware. NVidia and ATI didn't release specs. That resulted in what little dev talent there was being used to do reverse engineering. ATI has gone a long ways towards fixing this.
2) Insistence on cross platform support. Cross platform support means no device drivers - everything in user space. There are all kinds of security issues with everything in user space. This also mean no integration with the underlying kernel. OOPS isn't visible, VT interaction, mode setting, no intergration with framebuffer, etc. Insistence on cross platform means that one OS can prevent progress from occurring on the others. There seems to be some movement on this issue.
3) Failure to endorse OpenGL-ES as the core driver system. The embedded world went OpenGL-ES and ignores X (N810 is an exception). There is money in the embedded world and not in the desktop. The money went to OpenGL-ES.

From a developer's point of view the architecture of X has not evolved in a way where a developer can work on one chunk of the code without having comprehensive knowledge of the entire system. Requiring that level of knowledge really reduces the number of potential developers. Finally there is a giant amount of NIH that goes on.

Re:What exactly is X.Org missing ?

One interesting bit of reworking is MPX Yes, MPX looks quite promising (MPX demo video) and will also enable multi-touch which will be relevant for several areas of application (e.g. embedded stuff).

Re:As good as Xorg is...

[Sax Maniac]

On Windows, when an app hangs, you can't move the freakin' hung window out of the way, because the window manager is the hung app. So they come up with a stupid button which minimizes windows, and due to the way modal dialogs work, the application pops back up in it's hung state when you click on another application. I'll take the separate window manager, thankyouverymuch.

Network transparency

[Craig Ringer]

I'm constantly amazed by people trumpeting the same old line about how network transparency support makes X slow. It stopped being true before some of them were old enough to read and write.

Even if all traffic is forced though loopback TCP/IP by setting DISPLAY to '127.0.0.1:0' (or similar) it still performs quite fine. The network transparency isn't the slowdown.

The slowdown is the toolkits and apps, which miserably fail to consider the influence of network latencies. They issue requests and wait for them to finish before going on to something else. They issue lots of unnecessary requests, do things in inefficient ways, and love lobbing pixels around when higher level drawing instructions would do. Let's not even talk about the themes and styles used by current toolkits and apps (I just got a ~30x speedup out of thunderbird on LTSP by changing the theme!).

*argh*

Re:Lazy Developers

[lysse]

There are developers and users, and if the developers want to go open source they damn well need to accept that fact.

I have to say that I believe you are completely and utterly wrong about this. The segregation of users into developers and consumers is something that only happens when you actively prohibit the latter from being able to become the former - for example, by locking up the source code in the safe of trade secrecy. The whole point of free software is to break down the barriers between the two - to allow anyone to dip into development any time they need to, without subjecting them to restrictions or limitations. It's about empowerment. Of course, not every user will participate in development, for a whole range of reasons - but no user is prevented from doing so; every user is allowed to participate. And in that climate, the idea that there is some big glass wall between the developer and the user is simply ridiculous.

Yes, you are right, if someone had been paying, X.org would not exist.

Because X.org DOES exist and it's far more encompassing of varied hardware than any commercial project, we can conclude that it is NOT the work of one commercial entity. It's a cinch no one company could have pulled it off, it is something that could only (and did only) come into existence the way it did.

Thanks for making that point.

Re:MOD PARENT UP - HE MAKES A GOOD POINT

I'm curious why you think broad but lacking hardware support trumps a good working system for you. My experience has been that yes Xorg supports lots of hardware, but poorly, and therefor i have little reason to use it, and in turn i have little reason to use Linux itself BECAUSE the windowing system and input drivers and everything else that is built in to X11 (for some reason) function so poorly.

It's also been my experience that this is typical of community projects and software, ESPECIALLY GPL stuff, people work on the exciting stuff and leave the mundane parts of the system to rot and trail behind more modern systems.

There is no other explanation for me for why Xorg and X11 in general are so poor, no one is being paid to develop them like other competing systems.

Re:How close are we to being able to leave out X?

There's a lot of software out there that doesn't work with the Qt library directly--but I don't know enough about programming to know if that will matter. However, Qt is owned by Trolltech, and Trolltech is in the process of being acquired by Nokia. With Qt's currently using the GPL, Nokia may (or may not) continue to use that license for future versions.

Re:How close are we to being able to leave out X?

Two problems with this.

1) As another poster said, remote displays are still in common use. I use ssh with X forwarding every day at work so I can have my desktop on one machine while running apps on other machines. It's a lot easier to do this than messing around with multiple VNC windows. You simply can't do this without X.

2) Qt still needs some type of display device drivers to interface to hardware. Presumably, those smart devices had streamlined display drivers linking Qt directly to the display hardware, but that's a lot easier to do on a small device with only one possible hardware configuration. In addition to all the display abstraction stuff, X is also a framework for display drivers. Even if you dump X, you'll still have to fork off all the display drivers it comes with, and come up with a new framework to deal with these and interface them to the kernel and apps.

Personally, I think there's definitely some stuff in X which just isn't needed any more, such as the print server. But those things aren't central parts of X anyway, and are already easily omitted.
