    As David W points out, XFree86 is around 11 years old. I was around when the project was started and was a low-key member (my name was all over the documentation for many years afterwards and may still be, I haven't checked for a long time).

    Anyway, one thing that rarely gets mentioned is how XFree86 itself was a fork. A fork from a recalcitrant developer, namely Thomas Roell. Roell went on to be a principal (probably founding) engineer at Xinside, later renamed Xi Graphics. Roell was the primary author of X386 which was the only freely available X server for x86 systems (typically SVR3 and SVR4 unices from a handful of companies like AT&T and Dell - yes Dell actually had their own Unix distribution and it was pretty kickass too). X386 had limited chipset support (IRC, Tseng Labs ET4000 was the faster chipset it supported) and little if any support for hardware acceleration.

    Anyway, the story gets a little murky here, because I wasn't in on all the background machinations, but a couple of developers who are now in the core group (DavidW for one, and I'm thinking David Dawes and Tsilias, but don't quote me) got together and forked their version of X386 to add support for more chipsets and more OSes, kinda leaving Roell (unhappily) in the dust. It didn't help that Roell's got an ego (which he *mostly* deserves) and that DavidW had a kind of angry-young-man online persona at the time either.

    It appears that Roell eventually got over it, but never enough to join in the fun. Instead he went on to do commercial X server development, ultimately at XiG.

    But, the moral of the story here is that XFree86 itself (even before it had a name, I remember the vote on the mailing list, I didn't vote for it, thought it was kinda dorky, but I guess my own suggestion was even dorkier since it didn't win) is a fork of code that was floundering and not being developed fast enough for the tastes of some people. People who were willing to put their code where their mouthes were and to improve the situation, and who didn't really care too much who they pissed off in the process as long as the end result was a big improvement - and that it definitely was.

    That's hilarious. Graphics hardware has gotten so advanced, that direct access actually *hinders* performance because it prevents the graphics card from optimizing things as well (a developer for the BeOS Radeon driver once told me this). DirectDraw has been getting significantly more abstracted, to the point where it was put on top of Direct3D which, like OpenGL, is a quite high-level abstraction. Look at the way current graphics cards are designed to run:

    Making individual calls to the graphics hardware (over the AGP bus) to draw each element is hideously slow. Instead, graphics hardware is designed to take a pointer to a memory region containing a big batch of drawing commands. The CPU fills the command buffer, sets up a DMA on the graphics card, and waits for an interrupt for the GPU to finish processing. As a result of this, OpenGL implementations work the following way: the OpenGL library (in userspace) creates a command buffer from the OpenGL calls the application makes. When the command buffer is large enough (or the application does a flush), it makes a (expensive) call into the kernel driver, which sets up the DMA and drawing operation and returns control back to the app. Notice, that because of the batch-orientation, the performance bottleneck is not in the communication between the application and the hardware.

    Some have suggested that this was a secret attempt to undermine the XFree86 project: this was not my intent. I have tried as hard as I can to work within the existing XFree86 structure.

    It's hard to think that this is some kind of misunderstanding. Either Keith has been lying, or else he hasn't. It's impossible for us to really decide for ourselves, since the emails containing the alleged lying are not public.

    There is an email thread documenting this. Some members of the BOD wanted to post the email, or quotes therefrom, with the announcement. I and some of the others were utterly uncomfortable doing that. I don't think anyone on the BOD or Core Team would have any issues with an independent audit of this email thread, if there are concerns about the veracity of what I say, but airing that in public isn't appropriate, IMHO.

    I'd like to see someone I trust given the job of auditing those emails, and judging whether Keith Packard has in fact been lying.

This decision affected several things about X, and made the X API's extremely difficult to learn (pick up an X book, you'll see), but extremely powerful.

    Basically, what some people are saying is that that decision was wrong - that it's not correct to design an entire graphics API around the concept of displaying windows locally and remotely.

    Really, the most objective way to analyze that claim is to look at how many windows users open on their own workstation, versus how many remoted X applications they run. Compare that percentage. Then take a look at how much more complex X was made to handle the eventuality of having to handle remote windows, etc, etc. Is it worth it?

    Me personally, I don't think so. The only real use I've had for remote X applications was in terms of systems administration - but this is stuff I could have done as easily with something like ssh, or, if I needed some kind of graphics, PC Anywhere, or Timbuktu. And for applications to be faster, better behaved, and less bloatey, I'd be willing to install some PC anywhere-style application on the occasional remotely-controlled server.

The very thing that Windows has been criticized for since NT 3.51 came out.

    Yes, it is true that if people wanted to, we could move X11 into the kernel, in analogy to what NT did. We have moved the NFS server into the kernel for the same reason. X11 is probably leaner than the NT graphics subsystem that got moved into the kernel, so this wouldn't be a big deal. However, we really don't need the maintenance nightmare. Keeping X11 in user mode is a sensible choice, even if it costs some performance.

    Get rid of X and you have a desktop OS that can actually compete. You DO NOT abstract the windowing system first and then tack stuff to it (say "OpenGL") - you put the graphics close to the metal and then abstract that instead.

    The graphics is close to the metal in X11: you send the server a bunch of high-level operations you want it to execute and it does it for you, using hardware acceleration and highly optimized drawing routines. X11 is really like Apple's Quartz in that regard, only that X11 uses a more efficient binary protocol (server-retained vector graphics is an extension for X11).

      Moz *is* a pig, but on this machine even it can scroll the /. comment page for this story with no perceptible lag.

      IMHO the real killers are:

      1. Slow anti-aliased fonts. I nearly wiped Red Hat 8.0 off my hard drive before I found the option for turning off AA fonts. (At 1600x1200 they're more of a liability.)
      2. Some video card drivers are slow.
      3. Some apps do things that suck under X, like loading common images to the server *every time they're displayed*.
      4. Window managers do dumb things, like excessively redrawing apps when you switch virtual terminals.
      5. Poorly-implemented eye candy. It's pretty easy to kill performance if you go sticking shading and bitmaps on all your widgets.

    2. Re:Myth of X slowness by guzzloid · · Score: 4, Insightful

      It's wrong to blame X for slowness.

      Rubbish. On my home machine, Win2K is fast, X is slow. I'll address your points individually: 1 .Slow anti-aliased fonts.

      I have anti-aliased fonts in Windows. It ain't slow. If X provided a decent standardised AA fonts interface that was correctly integrated into it's core functionality, then this wouldn't be a problem. AA font rendering should not be that CPU or GPU intensive. It's been around for years -- it's not THAT hard a problem. If a PDA can do sub-pixel font rendering, then a Pentium III shouldn't have much of a problem.

      2. Some video card drivers are slow.

      Agreed, but most of the intensive rendering on my machine is using the same driver (nvidia). If pixmaps didn't have to be uploaded to the server, then perhaps there wouldn't be a problem. If uploading to remote servers was transparent, and handled by the windowing system itself, then it shouldn't be a problem.

      4. Window managers do dumb things, like excessively redrawing apps when you switch virtual terminals.

      Yes this does happen. But have you ever compared the number of redraws under X, compared to the number of redraws under Windows by running on a slow PC? Windows does much more redrawing (how many times does it really need to draw my desktop icons every time I press Win-M, for example?!) yet manages to run its display faster than X on most systems. Again, eye candy is fast on Windows, slow on X, on the same machine with the same drivers and the same video card.

      5. Poorly implemented eye candy. If X had decent alpha-channel support, decent pixmap caching and hardware accelerated shading or speedy direct rendering, then we wouldn't need poorly-implemented eye candy hacks.

      C'mon, I like X, and it's got a lot going for it; but I can't pretend it's not a slow resource hog. X can't even blit a window around the screen at full speed. And that isn't my video card slowing it down(my card can do this in it's sleep), or my drivers(because I can do it blazingly fast using GGI, DirectFB, or SDL): it's X itself.

      In short, I think all of these concerns could (and should) be addressed by improving the underlying X architecture. The app layer needs to be brought closer to the hardware display layer.

      And while we're on the subject, can't somebody come up with a decent accelerated video display architecture that works on the console and under X. Sure, it can be done: but do you use GGI, KGI, SDL, DGA, X11, DirectFB, plain framebuffer, svgalib, ... ?? Surely somebody sees the need for a unified linux display architecture? Would save a hell of a lot of heartache writing video drivers..., not to mention choosing APIs...!

      Don't ask for much, do I? ;-)

  32. DirectFB by vandan · · Score: 4, Insightful

    I'd like to see DirectFB take off.
    It looks pretty cool and is quite fast.
    Don't know how practical it is or what issues are involved, but anyway if the X ship is sinking, I'm voting for DirectFB.
    Of course the X boat is not sinking though.
    All those who are sick of X can just stop using X, and see how you go ... ha! I don't know what most people are whinging about. X is incredibly fast on my computer. I run Enlightenment-0.16.5 and Enlightenment-0.17. And yeah I use network transparency a little. That's cool too. And my games run swift as lightning. Direct Rendering is sure working. Is X really that bad that people need to dump it and start again? I'm not convinced.

  33. XFree86.org = ICANN by dh003i · · Score: 4, Interesting

    Quite frankly, the whole stink with XFree86 reminds me very much of ICANN. Technological snobs who won't listen to anyone else, have closed off public participation, aren't transparent, and now are defaming someone who rightly criticizes them. Furthermore, they are blundering. Why should Xfree86 drivers not be modularized? I only have one fucking video card. I don't need to download the drivers for every video-card Xfree86 supports. Xfree86 has also done an atrocious job of integrating the latest drivers from graphics chip corporations, like ATI. Their failure to promptly incorporate these drivers has alienated hardware developers. Why should ATI spend millions of dollars to make drivers for XFree86, if it takes them so long to incorporate them?

    The actions of XFree86.org convince me that they want to restrict user choice in the GNU/Linux world, and prevent anyone else from running any X11-implementations other than XFree86. Their refusal to modularize drivers is one thing convincing me of this.

    I can not think of any major projects which are as poor as XFree86 in regards to including the community and being accountable to the community. Many of the people within that "organization" are in fact figureheads who don't even believe in XFree86, like one of the founders linked to. If you don't use XFree86 at all, and only use Windows, then imo, you have no business being part of an XFree86 team.

    Keith is right to fork off XFree86. He has tried to address his concerns from within the organization, and has been unable to do so. Just like Auerbach. There is only so much one crusader within an organization can do when the rest of the organization is bent on corruption.

    XFree86 is proof that even a project covered under a license approved by the OSI and the FSF can be corrupt and non-transparent.

  34. There was a reason for the shakeup in FreeBSD by phkamp · · Score: 5, Insightful
    All I can say is that there were a lot of similar reasons why the FreeBSD project went from a self-elected core team to a core team elected by the committers.

    Reading Wexelblats email where he basically tells people that this is none of their business, is like hearing an echo of the argumentation launched against new bylaws in the FreeBSD project.

    If David is not actively contributing to XFree86, he has no business telling anyone how to run the project.

    I think the active developers of XFree86, both committer and non-committers, should grab a copy of the FreeBSD bylaws and elect a new core team.

    The FreeBSD bylaws are far from perfect, but it would be enough to get started and once the dust has settled, a revision to more closely match the needs of the new project can be made.

    David Wexelblat is in the Xfree BoD. He's also a core-developer. He flamed Keith Packard because of what he has done. What has Keith Packard done for Xfree recently? Among others:

    d) Only thing he does related to Xfree is to lurk in the core-devel mailing-list

    And here we have Wexelblat flaming Packard! Hello!?! Of the two, it seems that Packard cares ALOT more about Xfree than Wexelblat does! He actually works on it and improves Xfree, while Wexelblat plays Myst on Windows! Looking at their recent activities, Wexelblat should just shut the hell up. He hasn't done a thing, who the hell is he criticizing Packard!?

    Wexelblat should be kicked out of the BoD and Core and replaced by someone who wants to work on the project and improve it! It's no wonder Xfree has stagnated if there are core-members like Wexelblat who haven't contributed to the project in years! Ironically, it was he (if I remember correctly, could have been someone else as well) who kept reminding that "Xfree is a meritocracy". If it's a meritocracy, why are there useless deadbeats like Wexelblat in Core? Because of their past accomplishments? Maybe Wexelblat was an uber-hacker 10 years ago, but TODAY, he contributes nothing to the project.
