Bug description:
  SRU testcase

  1. install unity from precise-proposed
  2. make sure unity does not crash while enabling/disabling a plugin in CCSM

  I have problems with alt+tab. When I use it the bars where are
  (close,minimize and maximize) disappear. And compiz is not even
  installed. I installed it and try to make some changes but it almost
  always crashes and I can't even reboot with terminal. System freezes.
  I thing maybe is something to do with VGA drivers, because when I
  installed 12.10 when I move windows they appear to lag like I have low
  fps. My VGA is nvidia 450GTS and now I am with 295 .20 drivers which I
  install from app "additional drivers".
