X crashes and returns to log-in when starting certain games

[testingtester]

New install of Gutsy Tribe 5 desktop-amd64. Tried nvidia-glx (using Restricted Drivers Manager) and then a new install with nvidia-glx-new (from terminal). Exactly the same happens with both.

X crashes when I start Gnubg, Torcs, Chromium and Neverball. All OpenGL games?

Guess I should attach complete files. Here's Xorg.0.log.old

Could be a duplicate of Bug #130325.
Besides that, I can confirm the problem with Gutsy Tribe 5.
Seems that any 3D accellerated Game makes X crash and restart with the login sceen.
HW: Intel Core2Quad, Nvidia 8600 GT with restricted drivers from Nvidia.

testingtester:
Can you confirm that running glxgears crashes X? Can you also indicate whether turning off desktop effects allows glxgears and the previously mentioned games to run?

[Sebastien Bacher (seb128)]

the backtrace indicates that X is crashing, reassigning

[testingtester (iain05)]

I've since installed kubuntu-desktop packages and the games run fine under KDE, with effects and without.

glxgears causes same crash in Gnome.

Turning off desktop effects solves the problem. No crashes after disabling effects with glxgears or any of the games.

[testingtester (iain05)]

The default set up in gnubg is a 2D board, but some 3D effects are used.
If you go Settings > Appearance > Lighting tab you have Light azimuth and Light elevation sliders.
Chequers tabs have Refractive Index, Dull-Shiny and Diffuse-Specular.
Chequers (0) also has a Flat-Round slider.

gnubg is what caused the first crash. I installed Gutsy, updated, used restricted driver manager to install graphics drivers, restarted, installed gnubg and then ran it. The first time it ran I was able to go to the View and Settings menus changing some options. It crashed when I clicked Settings > Appearance. After that it crashed every time it started.

I then disabled the nvidia drivers, going back to nv, and tried gnubg again. I got an error that "The windowing system does not support OpenGL" or similar. I reinstalled nvidia-glx and installed some other OpenGL games, which all cause the same crash.

[Sitsofe Wheeler (sitsofe)]

As Dirk said, this sounds like Bug #130325 ...

[testingtester (iain05)]

Yeah, it must be. I searched but didn't find anything.

this is because my desktop freeze after login

I don't think this is a dup of 130325!

Please see my comments in 1228207.

Basically, this bug is elusive, and evidently manifesting in different ways (eg by running gl games, screensaver, or as in my case, just by attempting to switch from GDM console to text console (ie looking at GDM on console 6, and pressing Ctl-Alt-1 to go to console 1, and machine hangs cold!)

So I suspect this is some sort of race/threading problem, or at the least, something at a lower level in Xorg!

My drivers are Intel standard built-in, other people has been Nvidia, etc, so not driver-specific as far as I can tell.
