Title:
  (i915) Black screen resuming from suspend

Status in linux package in Ubuntu:
  Expired

Bug description:
  Similar to Bug #1336227 and Bug #966744, intermittedly when resuming
  from suspend I get a black screen with only a visible mouse pointer.
  Sometimes I can move the mouse pointer. I have the feeling it occurs
  more often when disconnecting an external monitor while in suspend.

  I can always switch to a VT, and sometimes I'm able to get everything going again by killing compiz and restarting unity:
  >>> killall -9 compiz
  >>> unity --replace &

  But most oft, only way is to restart the lightdm service...

  All the best,
  Niklas
