Description Tomasz Cwietkowski 2010-10-08 07:44:59 UTC 
Using open source drivers with Ubuntu 10.04 2.6.32-25-generic
nVidia Corporation G86 [GeForce 8600M GS] (rev a1)
nvidia-current
nv,
nouveau,
resulted minor problems -  2d artifacts and X crash after 1h - a few days
from Xorg.0.log
[mi] EQ overflowing. The server is probably stuck in an infinite loop.

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

0ubuntu5 is NEWER than 0ubuntu3, hence that is no "downgrading" but "updating".

Also, why is this a GNOME issue and not an Ubuntu issue? Did you file a report in Ubuntu's bugtracker?
Comment 2 Tomasz Cwietkowski 2010-10-21 23:27:09 UTC 
I am not familiar with versioning in ubuntu but in the synaptic I had to
force older version and this version was marked with star.
and
2.30.2.is.2.30.0-0ubuntu3 in my opinion is higher than 
2.30.0-0ubuntu5 
because 2.30.2 > 2.30.0

Also submitted as an Ubuntu issue.
https://bugs.launchpad.net/ubuntu/+source/gdm/+bug/657336

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.

In mine it isn't. Please ask Ubuntu...
