The i915 is giving me lots of problems. After upgrading to 12.10 I had a blank screen after logging in (using Unity).
There was a kernel BUG at drivers/gpu/drm/i915/i915_gem.c:3084! in my syslog, so I first upgraded to 3.6.3 as suggested in https://bugs.launchpad.net/bugs/1058546 and that got rid of the BUG message, but still a blank screen.
Then I upgraded unity (using ppa:unity-team/staging), and know I have a working screen.
Nevertheless it keeps bugging me with a popup about a hangcheck timer GPU. I forgot which bug#.

FYI, using XFCE avoids the problem too.
