Title:
  Display Port on Nouveau breaks with linux 3.13.0-24

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I have been happily using 3.11.0-19 since upgrading to 14.04 LTS.
  Over the weekend I allowed the system to update to 3.13.0-24.  While
  my laptop is undocked, the display works find (built in display).
  When I dock the laptop into the port-replicator which has 2 monitors
  attached via Display Port, the screen becomes severely distorted (very
  low resolution and many artifacts).  The only way I could get the
  system working again was to pick the older 3.11.0-19 kernel from Grub.
  For this reason, this 'ubunut-bug' collected information about the
  good configuration.  Due to the level of corruption I don't believe it
  would be possible to collect a report while running the broken kernel.

  Please fix.  This is a horrible regression.
