Title:
  X crashes and goes back to login while the screensaver runs

Status in “xorg-server” package in Ubuntu:
  Expired

Bug description:
  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 
returns -5 (awaiting 15549 at 15524)
      [  369.100021] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer

  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.
