Title:
  External screen turns grey or green after some random time.

Status in xorg package in Ubuntu:
  New

Bug description:
  As in the title the external screen attached to my laptop through
  Displayport suddenly turns grey and I have to unplug/replug it in
  order to get the environment to appear again.

  This bug started appearing after installing the latest updates
  (2015-04-14) that included linux-headers-3.13.0-49-generic:amd64.

  I have in the past installed the Intel Linux Graphics drivers which
  apparently are now causing some problems with 14.04 so the problem
  could also be caused by that.
