Title:
  10de:06e9 [Acer Aspire 4935G] "Graphical freeze" or extrem slowdown

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  The system kind of "freezes" randomly (opening Unity Dash, browsing
  with Firefox, opening LibreOffice). Moving the mouse or using keyboard
  shortcuts that result in a graphical reaction don't produce an
  immediate result but eventually an result at a later time (sometimes
  up to 5 or more minutes later). Sometimes there is also problems with
  the graphical output (parts of the screen become black). To get out of
  this "freeze" it helps to switch to a console (ctrl+alt+f1) which
  works almost immediately (sometimes takes a few seconds but faster
  than anything else), then switch back using ctrl+alt+f7. The system
  works as expected again.

  This is on an Acer Aspire 4935G with NVIDIA graphics (proprietary
  driver).
