Title:
  Xorg freeze

Status in xorg package in Ubuntu:
  Expired

Bug description:
  As you will be able to tell from the log files, I am testing out
  Utopic on an iMac. Prior to experiencing these problems I had been
  using 14.04 with no display problems whatsoever.

  If I use the nouveau driver then I get regular 100% CPU spikes in
  /usr/bin/X. If I install the recommended nvidia driver (nvidia-331)
  and reboot then lightdm appears for a few seconds and then I get a
  blank screen (or I manage to log in quickly but then it locks up once
  we're in Unity, Gnome, KDE, LXDE or Cinnamon - tried them all!). Once
  it's reached this state, if I SSH to the machine and run htop then it
  indicates 100% kernel CPU usage (i.e. the htop CPU usage bar is
  coloured entirely red); although no individual process is listed as
  using more than 0.5% CPU or 2.5% RAM). Load average is 6.0-8.0.

  I have created a new user account in case it was a setting in a config
  file somewhere in my home directory, but I get the same result with
  the test account.
