Bug#572134: xserver-xorg-video-intel: i915 945GM gpu crashed after resume
Feeling adventurous, I decided to upgrade to xserver-xorg-video-intel
from experimental (2:2.10.902-1) and kernel
linux-image-2.6.32-4-686. This seems to work fine for me. After a
couple of suspend/resume tests, it kept working.
So for me, this bug can be closed.
Just for a bit more info: pm-suspend worked fine, and Fn-F3 also, but
closing the lid resulted in the problem earlier.
Thanks,
Mark
