Title:
  Unity fails to start with a 4K monitor attached

Status in Unity:
  New
Status in “unity” package in Ubuntu:
  Incomplete

Bug description:
  I am running Ubuntu 12.04 LTS on a Dell XPS 13. This is an Intel
  i7-3537U integrated graphics setup.

  When I boot and log in and THEN attach a 4K monitor via DisplayPort
  everything works well.

  But when I attach the monitor and then boot, after logging in, Unity
  fails to start. It seems to be unable to allocate a OpenGL surface.

  Why the difference between startup and hotplug?
