X and the whole ubuntu crashes ( reboot, unresponsive keyboard, vertical
stripes on the screen )
Downgrading Ubuntu to 2.30.0-0ubuntu5 resolved this problem
Best Regards

I am sorry but downgrading to gdm 2.30.0-0ubuntu5 didn't resolve the problem. The error is still present.
My case most likely is following :
1. the bug occurs -> [mi] EQ overflowing. The server is probably stuck in an infinite loop.
2. overheating of nVidia Corporation G86 [GeForce 8600M GS] (rev a1)
3. artifacts are present
4. crash of X or whole Linux
The GPU usage is important - Dual screen and high resultions are the reasons of more frequent overheating and crashes.

Hi,
No I am not experiencing. The problem is complex, but the gdm issues
were only a trigger for over heating problems. So I think that the
vertical stripes, crashes were not caused drectly by the gdm bug, but
due to Nvidia chip overheating. Probably using another machine ( hp
pavillion dv 98xx is badly designed ) I would never notice gdm bugs.
Best Regards,
