Bug Description
My desktop session crashes sporadically. Often this happens when I leave the computer and the screensaver starts (Euphoria GL screensaver). This bug is not reproducible on demand.
Attached is my Xorg log file which seems to indicate that this problem is related to the i915 driver code.

The crash just happened again... this time it looks like it was related to fullscreening a video on facebook.
I should probably also mention that I have a dual screen setup.
