Title:
  Purple line appears on the external monitor after it is turned off and
  back on

Status in The Linux Kernel:
  Fix Released
Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I have an external LED monitor connected to my laptop via HDMI. When I
  first log in everything seems to be fine, but when the monitor turns
  off due to inactivity and then turns back on, I see 2 pixel wide
  purple line on the left side (photo attached).

  I got the same issue when I tried upgrading kernel to 3.2 in Ubuntu
  11.10

  The same happens in Unity 2D and 3D, so I don't think it's a Unity
  problem. It's probably either kernel or intel driver.
