The same thing in my Toshiba laptop.

With 2.6.15-22 kernel version glx worked great over a 8mb 3D S3 Savage IX Graphics Controller. But in the next -23 version glx crashes and 3D games just show a black screen.

@ozroc:

are you sure the bug lies on kernel version? yet i believed it is anything around xorg. have you tried the old kernel version with your uptodate system?

i just know that it works fine with the flight 7 cd and it does not work with the final live cd.

i have spend much time to detect the critical difference. but i have deinstalled the old kernel - so i have not tested this.

Well, I can't be absolutely sure, but I think so.

When I upgraded to -23 kernel version it just stopped working, and in that
moment xorg was exactly the same version.
Something wasn't working well (also whith some features in XFCE) and decided
to burn the new ISO and make a clean installation because I've been working
from long with a Breezy dist-upgraded to Dapper.

Now with a clean system the problem persists. I can't reinstall -22 kernel
version because it isn't in repositories, but in that moment, when both of
them were installed, booting one of them allowed glx perfectly and not the
other.

Excuse my poor English, hope you understand.

@ozroc:

thanks for your hint. i believe it is the kernel because between version 2.6.15-22.34 and 2.6.15-23.35 there are patches on drm - see:
http://changelogs.ubuntu.com/changelogs/pool/main/l/linux-source-2.6.15/linux-source-2.6.15_2.6.15-23.39/changelog

i am not so familar with self compiling kernels. but it would be nice to test if the problem persist with a self compiled kernel from source version 2.6.15-22.34:
https://launchpad.net/distros/ubuntu/+source/linux-source-2.6.15/2.6.15-22.34

see bug #30382 too.

Well, it's confirmed that changing between 2.6.15-22.34 and -23 without any
other change in xorg or something else makes glxgears work or not.

I have now both kernels installed and with one glx works but with the other
one not.

I also tried both of the kernels for i386 and 686 and happens the same, with
both 2.6.15-22 versions glx works and not with any of them from 2.6.15-23.

I hope this can be usefull.

hmm .. it seems to me that you have identified the critical package. i will send this information to bug #30382 too. i hope there is a developer out there who can fix the actual kernel package. perhaps we have to make a new bug for linux-image?

regards ,

prinz igor

Not confirming which package is at fault here, just adding kernel so we can work together.

The last update to linux-source contained a lot of DRI updates. This was needed in order to fix a huge amount of bugs with ohter chipsets. This was done in conjunction with the DRI upstream maintainer (he actually did the backport for us).

So, I will try to find out if the needed fix is in DRI, or in the xorg driver (perhaps it needs to be updated).

@Ben:

thanks for your attention. i did not have exactly understand what to do now. how can i help? do you need any further informations?

when i not err the xorg driver (xserver-xorg-driver-savage) is the same under flight 7 (working) and final (not working) ubuntu. so i do not believe it is the critical one.

it is the kernel. with version <= 2.6.15-22.34 it works and with a greater version it does not.

hello,

what's going on? does anyone work on this bug?

i would like to help - but do no know how.

@ozroc: could you tell me how to compile the older kernel versions? i have tried but without luck. which configuration have you used? it would be very, very nice if you could post a short step by step description of what you have done, please.

I didn't compile the kernel, I just downloaded a precompiled one.
It was a bit difficult to find, but I finally did:

http://librarian.launchpad.net/2518299/linux-image-2.6.15-22-386_2.6.15-22.34_i386.deb

If you want to compile by yourself, it's not so difficult, here is the
buildlog:

https://launchpad.net/+builds/+build/191298

But if I wanted to compile my kernel, I'll be using Gentoo ;p

It's much easier to wait for a future release running this old kernel...
(I'm so lazy...)

I hope future versions will work better, but for the moment, this kernel
makes everything work quite well in my laptop, and it's enought for my
needs.

thanks ozroc for the link to the deb-file.

i have now tested 2.6.15-22.34 (ubuntu-version) and 2.6.15 from kernel.org. both do the job fine. 3d acceleration works without any problems.

additionally i have testet 2.6.16.20 from kernel.org. with it 3d acceleration does not work.

i hope this will be fixed in the future. until that i use 2.6.15 from kernel.org.

mfg,

prinz igor

a little bit more testing:

2.6.15.7 from kernel.org works fine.

2.6.16 from kernel.org works not.

so the bug lies in patch-2.6.16 (see kernel.org).

changelog of this seems similar to changelog between ubuntu version 2.6.15-22.34 and 2.6.15-23.35.

hope this helps.

Not that simple in my case. I tried precompiled 2.6.15-22.34 kernel (and dapper's final X) and all the same as several months. glxinfo segfaulting before printing last section, any opengl app crashing X and leaving (plain 80x25) console in mess. So just a "little" change from original bug #30382.

Update: with Xorg 7.1 and kernel 2.6.17 from current edgy runs glxinfo flawlessly, but glxgears get immediatelly killed (attached it's strace) and e.g. ppracer freezes whole X.

This bug probably is fixed on git now. Take a look at https://bugs.freedesktop.org/show_bug.cgi?id=6357.
I'll be able to test this git snapshot next week only.

I can confirm this on my system, using an S3 Inc. 86C380 [ProSavageDDR K4M266] (rev 02), which according to Xorg.0.log is a "Twister PN133", Chip: id 8d01.

After asking at the xorg mailing list, they directed me to the bug Marcelo Shima was pointing out on his last comment.

I can also run glxinfo, but executing glxgears results in a black window and 100% CPU usage.

So basically, it seems that the DRI locking was broken in the driver, and that that has now been fixed upstream using the following patch: https://bugs.freedesktop.org/attachment.cgi?id=7041 (see the bug report for more information)

Sounds like a xorg problem then.

I've just tested this patch, which I created by adapting the upstream one (https://bugs.freedesktop.org/attachment.cgi?id=7041) to the current edgy package (1:2.1.1-0ubuntu2).

The patch seems to fix the glxgears issue for me (now I can run glxgears flawlessly) but since I do not use any other 3D applications on my system, I cannot really tell if 3D acceleration overall is working 100%.

Could anyone else test this?

I had the same problem and tried your patch and it works flawlessly.

Thank You :)

// JockeTF

A new upstream version was released and. This new version fix this bug. It's available on debian already.

Release 2.1.2
EXA support (copy and solid only)
PCI BAR refactoring (preparation for PCI-rework)
fix DRI locking
bug fixes

Nice.

Now let's just hope it makes it into edgy.

I can also confirm that Bernat's patch fixes the problem I had with glxgears on savage. If more people would like to check if this patch works, I have made test packages (using pbuilder) here:

Daniel, are you sure the patch got applied? The build log only mentions the other patch:

Applying patches...successful.

Daniel, forget that last remark, I think it justs lists the first patch anyway. The package seems to work fine, thanks.
