Title:
  Unity(7) freezes completely after Kernel update (3.18.0.9.9) on intel
  GMA-965 (Vivid)

Status in compiz package in Ubuntu:

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  After I update the kernel to 3.18.0.9.9, Unity freezes few minutes
  after login on Vivid. This happens for any compiz based session like
  gnome-flashback(compiz). I tried booting with both the systemd &
  upstart from boot menu, but the outcome did not change. Ctrl+Alt+F1 or
  Alt+SysRq does not work after freeze.

  Just before the freeze syslog prints following error:
  ----------------------------------------------------------------------

  I have attached the complete syslog.txt  & xorg.txt
  (http://paste.ubuntu.com/9852608/) for the session.

  It could also be a bug in kernel, however It does not crash at all on
  non-compiz session like Gnome-Flashback (Metacity).
