drm i915 hangcheck...

[oblador]

Hi friends,

I'm running Ubuntu 11.04, Unity (3d, default), whole system updated.

Once in a while the screen turns to black, the keyboard stops responding, everything freezes.

I checked my /var/log/syslog and I got this:

My video is Intel GM 965, what can I do in order to use Unity 3d without getting this kind of problem?

Thank you.

Hey,

I am also getting the same kind of problem. Whenever i have locked my screen for around 30 minutes it is kind of restarted. I have checked the dmesg also, where i found like -
