Public bug reported:
While the (blank) screensaver runs X will randomly crash, quitting the
session and going back to the login manager.
These crashes are random but far more likely to happen if Eclipse is
open: I can reproduce the crash 90% of the times with an open Eclipse
window, 30% of the times with no open windows.
The dmesg log is full of
[ 368.351270] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer
elapsed... GPU hung
[ 368.351275] render error detected, EIR: 0x00000000
[ 368.351294] [drm:i915_do_wait_request] *ERROR* i915_do_wait_request

There are other similar bug reports in launchpad but they all refer to
freezes. In my case I only see the X session crashing and going back to
GDM. After that I can log in fine and everything will work until the
screensaver kicks in again.
