Title:
  [Apple Inc. MacBookPro9,2] dual head broken in 14.04

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

Bug description:
  Since I've updated to 14.04 I'm unable to use a dual monitor setup.
  When I connect the external monitor using an Apple VGA display port adapter both screens flicker and get garbled images.
