Title:
  [MacbookPro11,2] Using external displays show corrupted, flickering
  images

Status in xserver-xorg-video-intel package in Ubuntu:
  Incomplete

Bug description:
  Prior to install Wily Werewolf I could use external displays -
  including an Apple Cinema 27 (mini DisplayPort) and various projectors
  (Mini-DP to VGA). Since installing Wily external displays show
  corrupted visuals.

  For instance right now, when I plug in an Apple Cinema 27 the display
  initially shows the contents of my internal display prior to plugging
  in, but tiled and flashing on/off at about 1 Hz. The display does not
  update if I type a letter. If I move the mouse the flashing becomes a
  fast flicker, perhaps 10 Hz. The internal display recovers, once the
  cable is unplugged. I see similar behaviour with a 1080p television,
  using either the built in HDMI or  Mini-DP -> HDMI

  The same display and laptop work under OSX and previously worked with
  Ubuntu 15.04.
