Title:
  Xorg freeze

Status in xorg package in Ubuntu:
  Expired

Bug description:
  Several times per day, display freezes, with only the mouse moving.
  Clicks and keyboard have no effect, system monitor does not move anymore.

  Happens several times per day, randomly but usually after I perform a UI action such as moving the mouse.
  The exact same bug was already present in 2013.04

  I have found a workaround:
  - Press CTRL-ALT-F1
  - Log in
  - Type unity --replace (or unity --restart)
  - Press CTRL-ALT-F7
  - You can then use the system but various elements are missing.
  (Sometimes pressing CTRL-ALT-F1 then CTRL-ALT-F7 is enough)
