X crashes with opengl and desktop effects

Hi laucky,

Please attach the output of `lspci -vvnn`, and attach your /var/log/Xorg.0.log (and maybe Xorg.0.log.old) file from after reproducing this issue. If you've made any customizations to your /etc/X11/xorg.conf please attach that as well.

[This is an automated message. Apologies if it has reached you inappropriately; please just reply to this message indicating so.]

I'll supply more information if I'm asked to.

Hi Thomas

The Bug report looks very like the one I submitted. (Bug # 350766)
Does your screen freeze only after you have started a 3D application or does it freeze in general when Desktop Effects are switched "on" after 10-30 minutes?
My System runs totally stable when Desktop Effetcs are "off" even when heavily use with 3D Apps.

PS: I will try to post my log files tonight too

HI juhuu,
you have the same graphics card like me. You have my commiseration.

No, I have no problems with the 3d desktop effects (gnome). The problem appears only when using 3D apps (about 10-30 minutes after the start of the app).

I recognize heavy cpu load on one of my processors during the use of the 3d apps (but everything runs fluently), therefore I assume that some graphic computation is done by the cpu (I can't remember that was the case with fglrx). There could also be errors in the cpu-specific part of the driver (or the cpu itself, who knows)

Anyway: I don't know if my bug is a duplivate of yours. I'm not deep enough into kwin, compiz, opengl and such. BUT: I remember having similar problems like yours when trying out kde on jaunty a while ago. I don't know if they still appear, but I could test it if it really helps.

@Thomas Lauckner, thanks for confirming that you have the mundoplus.tv freeze issue. There is already an upstream bug for this and I will be sending off and e-mail to the devs once I've determined the full range of affected hardware.

The next step will be to understand in which package the bug really hides (-ati or mesa or xserver etc) and then use bisection to find out which commit caused this regression. The most interesting lead is that Bojan Kostic says he didn't have the issue in alpha6 ( https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/351990/comments/21 ) even though it has not yet been confirmed that he is suffering from the mundoplus.tv freeze bug and also I don't know how long he used alpha6 (maybe it just happened to not freeze during the time he had it).
