Slashdot Mirror

As many of you already know, Steam works fine in wine.

Ok, it may not be 100% perfect: it doesn't recognize correctly the microphone from my 100% original SoundBlaster (but probably it's only me) and sometimes has quite long loading times. But it runs fine.

However I had to completely get rid of it. And the most funny part is not for a Steam's fault (just my uneducated guess).
Preamble: check the Nvidia support forums for various references to "NVRM XID errors".
There are some really nasty bugs that occur to a lot of users while using the 3D features or CUDA from their video cards, which render the computer completely unusable and requires a reboot (remote CLI access still works).
Now, check again: for those about the 3D acceleration it's always when using software (games) via wine.
Obviously (sigh) I'm one of the affected by this. But everything is fine while using native code (videogames, blender, w/e).
That lead me to the conclusion that it's wine who triggers the condition resulting in the freezes. Perhaps a malformed call to a function or something, I don't know. And, I repeat, it's just a my completely uneducated guess.

At the end of the day, the net result is: no Steam via wine (or any other 3D game, for the matter) for me. I simply won't trade stability for some time (can be a few minutes, can be a few hours, not predictable) of entertainment.
So, it's about time we can have it natively. I'm really looking forward for this.

Perhaps not entirely coincidentally, "one month" is about the amount of time that nVidia's web forum - comically also the only route for reporting bugs, and found here - has been shut down due to a DDoS attack.

Probably not the best way to follow up their snippy response to Linus Torvald bashing their Linux support.

I can give them some ideas:

What about starting to properly support XRandR and stop the TwinView crap?

You mean like this? http://www.nvnews.net/vbulletin/showthread.php?p=2551804

What about continuing giving minimal support to old GPUs? My parent's computer has a GeForce FX Go 5300 which has currently no official driver that supports the latest Xorg.

There's also the issue of Linux support, not just to developers, but even the end users. As an end user, I've repeatedly been ignored by Nvidia when submitting detailed bug reports about their drivers, both to the support forum and by e-mailing linux-bugs@nvidia.com. Oh, and even on Twitter. Not even a "thanks, but we're not fixing this". Stone-walled. I won't be making the same mistake next time I buy hardware.

And as a parting shot at Linux users, Adobe introduces a major regression (hardware accelerated video tints everything blue, e.g. YouTube), claims it can't be reproduced, and closes all bug reports about it, leaving users to implement a nasty hack individually.

Why is it so wrong to use the proprietary drivers?

Here's an example. I bought a laptop with an Nvidia Quadro FX 3800M specifically for triple-head support (via docking station) and I can't even get dual-head to work properly due to an infinite loop somewhere in the binary drivers when mode-switching. I've done most of the investigation work, even running X through gdb and they're not interested in helping - not even some basic debug symbols.

I've been completely ignored by Nvidia via both of their official support channels: (1) the nvnews.net forum and (2) their linux-bugs@nvidia.com email address touted in their driver README. Even on Twitter.

What options do I have now with a binary driver except to run Windows (where triple-head works fine) or change hardware? I can't imagine why I would ever again support a company that can't even acknowledge my pain with their product, let alone help me to fix the problem myself.

If you use nvidia drivers with Fedora -- or at very least, do so with the aid of rpmfusion -- you may want to hold off on upgrading to F16.

To see if you should wait, run the following command:

nvidia-settings -q AccelerateTrapezoids

If you get nothing returned (or more accurately, two CRLFs), you will probably want to hold off on upgrading F15 -> F16. Looks like there is a bug in the nvidia drivers which can cause some pretty severe performance degradation.

Specifically, any card that can't handle trapezoid acceleration will suffer due to this regression. And to put it in perspective, my GT240, which is not ancient doesn't support this. So it's pretty bad.

More details: http://www.nvnews.net/vbulletin/showthread.php?t=166698

It /is/ apparently fixed in the 290.06 driver - but that's not in rpmfusion yet.

To be fair, screens are also order of magnitude larger than they used to be (even more if you count memory and not pixels, since 99% of us have 32 bits per pixel these days and back then 8 bit was common), not to mention that having 2+ monitors is now standard for desktops. This, plus proliferation of antialased rendering offsets advancements in CPU power - to the point that navigating source code in QtCreator on my Linux box is not that smooth as I'd like it to be. Generally speaking, concerns about font rendering performance are still relevant.

I've been researching about it since I found out. There are two categories of Optimus laptops... Those with a hardware multiplexer and those without. If you have the hardware multiplexer, you can disabled the feature in the BIOS. Alas, I have one without a hardware multiplexer. :-(

There is a open source project attempting to work around the problems called Bumblebee/Ironhide.

I just wanted better interactivity on a -rt kernel so for all I know this will not work,
furthermore I can't say I know how the nvidia driver works and I prefer not to know
either, this was just observing their glue code.

I can't even say for sure if/where os smp barriers are used, so that might be a

I had serious X issues with NVIDIA's closed binary drivers with my old Debian box with GeForce 5220 FX video card and AMD Athlon 64 754 single core system: http://www.nvnews.net/vbulletin/showthread.php?t=143606 ... NVIDIA fixed the problems in its later drivers.

Yes, I'm using binary blobs. I generally use the openSUSE provided NVIDIA repository with its nvidia driver RPMs unless I discover a bug that doesn't work for them.

http://en.opensuse.org/Nvidia contains a 1-click way to install the drivers.

If those fail me, I use the latest drivers from www.nvidia.com

If those fail me, I go to http://www.nvnews.net/vbulletin/showthread.php?t=122606
and download the latest beta driver.

Do you use the NVIDIA binary blob? I've a 8600M GT (mobile), the problem is poor performance in KDE compositing (moving a window isn't smooth, resizing a window results in less than 10 fps etc).

I'm not the only one with these problems, check out http://www.nvnews.net/vbulletin/showthread.php?t=115916 for example. I might give openSUSE 11.2 a try later, hopefully things have improved since last time I tried it.

How is openSUSE with drivers? 190.53 was released today for example - is there a way to install it in SUSE with the package manager?

In Ubuntu you have PPA:s, which often contain the latest software of things. (I always need the latest software - hence liking rolling release distros...)

The FreeBSD Nvidia 64-bit driver should be coming soon (a few weeks minimum): http://www.nvnews.net/vbulletin/showpost.php?p=2129411&postcount=445

God of War
Painkiller

Why, I have no idea how the two could have become linked in my mind as being similar :)

Though I did remember Painkiller as being a 3rd-person-perspective game, and it appears that it wasn't. Hm, Weird.

Anyway, they're both games where you slash your way through hordes of generic enemies and fight huge battles against gigantic gods (or demons). in Painkiller you hold down the left mouse button for long periods of time, in GoW you bash X (or whatever the plain "attack" button was) a bunch. GoW is more Gauntlet-ish than Painkiller, but they're not completely dissimilar.

I use the proprietary NVIDIA driver, but I just use the ones straight from NVIDIA rather than do it "the Debian way", or use someone else's bundled package. I wonder how many other debian users are doing that as well? As far as I know, this behavior wouldn't show up in the package tracking system. I do have gnome installed, but I never use it, also using e17, but I compile it from source using the svn repo., which also wouldn't show up in the package tracking system. I suppose the point is moot though, because I also don't have the package tracking system installed (I'm a big fan of only having the things that I want on my computer).

I suspect that my behavior is actually about par for Debian users, i.e. as TFA says, Debian users don't tend to install the default packages. I know I don't. I usually start with just the basic install and add the desktop packages I want because there are so many packages included in the default desktop that I don't want.

This post is TOTALLY offtopic. Really you need to split these up and file them as bug reports over on launchpad. I'll post a couple of comments answers but I'm not going to follow up on any of this (even if you answer any questions I ask).

- switching from dual display to presentation (clone) and back totally messes up x config, I have to uninstall and reinstall nvidea drivers

Talk to NVIDIA (Linux web forum) about this. It's their code you're running and they are probably the only ones who are willing to fix it.

- in dual screen mode, nautilus opens on the first display. I have to open terminal and run nautilus& to lunch it on the second display

You can't drag it? I don't quite understand...

- in dual screen mode, keyboard keeps focus in the previous screen. I have to minimize/maximize a windows on the "new" screen to move keyboard focus

Are you using desktop effects? (Do windows fade and slide etc?) If so this sounds like a bug in compiz...

- RDP client crashes X windows in some cases (it does not close the drop down list of used servers... and bang)

Hmm. I'm really curious now as to whether you are using compiz. Regardless your best bet with this one would be to be to see if you can capture a backtrace of the crash with debug symbols and to file a bug report against the RDP client (I'm guessing you're using tsclient) in launchpad.

- oh and NO it's not AN ERROR if I close the RDP window. If I want to reconnect, I will, don't hide under my active windows and bring RDP windows back in 30 seconds. That's just plain stupid.

I guess file an enhancement request on tsclient in launchpad.

- java and window decorations don't play well together (popups without buttons etc.)

I really would like to know whether you are using compiz. If you are I have a feeling this was a known "bug" in the Java bug database for a long time but the fix is not yet in Ubuntu.

- How about opening a connection to a new server in a new tab, not in a new nautilus window?

Hmm probably best to file an enhancement request over on the GNOME bugzilla.

- Flash stops working. I just see a gray square where flash is supposed to be.

64 bit Firefox using 32 bit Flash via nspluginwrapper I'm guessing. There is a 64bit Linux Flash plugin that is in very early beta that MAY work better for you (I've heard mixed things mind). Also make sure you're using Flash 10 whatever route you are taking.

- Firefox is not very stable.

Might be because of extensions or plugins or you may have found a problem page or your memory might be faulty or Firefox might be buggy or... You are going to have to sit down and capture the issue in Firefox this then file a bug report in launchpad.

- Windows would become gray and unresponsive when there's a lot of disk activity.

You're using compiz aren't you? The greying is compiz telling you that the window HAS become unresponsive! As to why this is happening on I/O it probably varies from program to program. Too little information to many possibilities to say more.

- I've seen ubuntu crash on my much more times than I've seen BSOD on the same HW.

Quite possible. I've seen Linux stable on some computers and fla

Ask and ye shall receive. Although application support is not quite there yet - there are patches for mplayer, and preliminary support in some branches of xine and MythTV; but it probably will soon be better.

(Not that I wouldn't welcome Nvidia opening up their drivers more, or at least offering proper XRandR 1.2 support. Unfortunately they still offer in my experience the best performance in Linux)

As a somewhat mystified recent purchaser of a GTK 260 from eVGA, I was amazed to discover that NVIDIA has such problems with their linux drivers. I owned one of their older cards before and built a new computer and thought it was a no-brainer to pick NVIDIA for linux (freedom issues are notwithstanding, but I decided to go with the pragmatic choice). Only after I ran afoul of the powermizer slow switching crap, or other weird issues such as the misreporting of the screen refresh frequency, did I start digging and realized how many problems there are. As it is, I've got the beta 180.16 driver installed and it's better but I still had to do some tricks to shut off the powermizer feature. Just this morning had some other weird problem with screen corruption that's never happened before with my old hardware but more or less the same software on top of it.

For me personally, I could care less if the card hardware is great if the drivers suck. NVIDIA, fix your linux drivers please. Next time I'll give a much harder look at amd.

NVidia just released their HW accelerated video decoding API
http://www.phoronix.com/scan.php?page=article&item=nvidia_180_vdpau&num=1
http://www.nvnews.net/vbulletin/showthread.php?t=123091

AMD pretty close to doing the same with their alternative
http://www.phoronix.com/scan.php?page=article&item=amd_xvmc_xvba&num=1

And Intel is backing VAAPI as well as apparently considering extending XvMC to support more recent video codecs as a stop-gap measure.

It's rather unfortunate that they're all separate and mutually incompatible (and presumably proprietary, for the first two), which will no doubt hinder adoption by application developers, but it's a lot more than what we had until now.

It seems like I'm always on the wrong side of the ATi / nVidia fence when it comes to Linux drivers.

So a few months ago when I rebuilt my primary Linux box based on the "$500 gaming rig", I plunked down $250 for an nVidia 8800GT. Unfortunately, the current 173 drivers don't seem to be able to perform anywhere near the level of even 7000-series nVidia cards under Linux. See this post:

http://www.nvnews.net/vbulletin/showthread.php?t=115916

The nvidia-settings -a InitialPixmapPlacement=2 -a GlyphCache=1 trick does do a lot to temporarily fix 2D performance. I'm starting to consider plunking down another couple hundred $ for a windows gaming box to put the 8800GT into for the time being, and getting a cheap PCIe card for my Linux box instead... but I'm not terribly excited about spending that kind of money just for entertainment value.

Five or so years earlier, I had bought an ATi Radeon 7500 All-in-Wonder sometime just after one of those several times that ATi pledged to commit to open source driver development. That never really panned out, but at least due to the excellent work of the excellent GATOS project, I could at least use the TV tuner and rudimentary OpenGL acceleration (without any FSAA or the like). When ATi finally came out with their proprietary FGLRX drivers, I don't think they included TV tuner drivers, and my aging 7500 fell just short of the cutoff for supported cards anyway.

Anyway, looks like I can't win :P Hopefully newer nVidia drivers will fix these performance issues with Linux drivers, until then, I can't really recommend 8000 or 9000 series cards to anyone planning on using them for Linux.

Closed source development, compared to the open source one, sucks the monkey's ass.
ATI released the specs, at least partially, and this is the result. That's why I didn't buy Nvidia.

Many others are experiencing issues. This is one of many threads like this on the Ubuntu forums where people are having serious issue with flash (especially compared to earlier versions (before 9.048). Version 9.112 and beyond (and even Beta) still are really slow, consume a crapload of cpu cycles and are in general unusable.

I've been researching this issue (mainly to get Hulu.com videos playable in fullscreen on a Mythbuntu setup) and have found no recourse other than playing the video at normal size, but using Firefox's zoom or turning on Compiz and using the fullscreen zoom to enlarge the video. Even so the video gets choppy occasionally and of course, is kind of a pain.

Right now full screen videos (using Flash's full screen option) use 90% CPU (out of 2 CPUs on an Athlon 64x2 4800+) and beat to death the poor Sempron 2800 I have on my Mythbuntu setup. Funny enough, the puny Sempron can play HD videos at 1080p with little or no issue.

After following countless threads (and the official bug report on Adobe's website), trying every 9 version and 10 beta, and so on I've pretty much given up on getting Flash to behave for now. Don't get me wrong, I believe you when you say it's playing fine for you, but either the issue is genuinely not affecting your system, or you haven't paid attention to cpu usage while playing flash. As always YMMV.

BTW, any hints not covered in the forums greatly appreciated. Getting fullscreen flash working is the last step in getting a web video based MythTV setup working.

Saying the the Mini should have a removable graphics card is like saying your laptop should have one too. Most graphics cards, even my old ATI Radeon 9800 are actaully longer than the Mac Mini. Have fun trying to fit an NVidia 8800 GTS in there. The Mac Mini makes a lot of compromises to fit into the extra small form factor. If you can't live with those compromises, then don't buy one. But I think that asking Apple to Redesign the Mac Mini to have interchangable video cards goes against the whole point of the machine.

After upgrading to Fedora Core 8, apt-get and yum install hasn't been too bad recently, although I did encounter some bad mojo with my Nvidia drivers which turned out to be that the GL library file is now in /usr/lib/nvidia and not /usr/lib, and is not longer called libGL.so, but libGL.so.1 - I ended up just deleting everything nvidia and starting again, then got error permission with /dev/nvidiactl.

Codecs work perfectly, but the installed fonts and desktop schemes seem to change according to the preferences of the current maintainer. A workaround to this is to make a manifest of all the rpm's installed prior to upgrading to a new release, then making a manifest of the new rpm's, then doing a diff and installing the missing rpm's.

Those are minor compared to having the installed anti-virus tools on Windows slow everything down because they are are doing their full volume scans in the evening or at night. Even worse is seeing how much disk space they use up with their virus definition files - this seems to run into hundreds of megabytes now.

And with any pre-installed ISP software, you can never be quite sure what information they are sending out (CPU ID's, local username, local current user directory). Remember the reaction when Real networks was sending back the filenames of the files that users were viewing.

At least with Linux, when you set up your own connection scripts, you know exactly what information is going where.

You pretty much want Twin View. Xinerama is sort of buggy.

Is this in SP1?

When NVidia finally implements Xvmc support in the 8 series I might start giving a shit about their products again. But I suspect by the time that happens the open source ATI drivers might be a real alternative. So I probably won't give a shit then, either. /angry at nvidia

Gamers hate it. It just plain doesn't run with the hardware that's out right now. I really think that Vista is trying to be the proverbial egg that comes before widespread manufacturer support (the proverbial chicken), but it's just not happening. Every gamer I know is avoiding Vista like the plague. As long as gamers aren't begging for Vista support in their high-end components, manufacturers are still going to continue to be reluctant.

Either you don't know any gamers then or you don't get around at all. Have you even visited a single nvidia related forum lately? There are countless threads and posts, especially here:

http://www.nvnews.net/vbulletin/forumdisplay.php?f =55

About users demanding that nvidia make their vista drivers better. The SLI users complain louder than anybody, because most of them want to get vista (assuming they don't already have it) and there is no SLI support to speak of yet.

Email if you need more help.

Yes, it still is supported, but it's only supported under the legacy driver which you need to dig into the Nvidia forums to find. If you try and use the most up-to-date driver with these older cards you'll get an error message in the installer telling you to use the legacy drivers.

I went down this road and followed their instructions, only to get a low res and odd looking desktop with the new legacy driver. After trying an array of different options and fixes in my X config file, I eventually had to drop back to the release before the legacy driver split in order to get a properly working desktop.

If you had referred me like the user you mentioned I would have been SOL on trying to get your game to work. At least if the driver was free I could have had a chance to figure out why exactly the old driver worked while new legacy driver didn't.

Does this patch in the FreeBSD nVidia forum fix it for you? It helped me on a 6-STABLE system with the 9631 driver even if the patch said it was for 7-CURRENT and the 9746 driver. I recommend it.
