** Description changed:

  Binary package hint: xserver-xorg-video-intel
  
- When trying to connect a Lenovo X201 to an external display it fails to
- correctly display the image.
+ When trying to connect a Lenovo X201 to an external display (24" LED
+ 1080p) it fails to correctly display the image.
  
  This worked perfectly in maverick. Right after upgrading the system to
  natty everything continued to work correctly. However, I believe that
  after updating xserver-xorg-video-intel later that day, everything
  started to malfunction. When the monitor is connected through VGA during
  boot, the external display shows flickering of different colors.
  
  However, when trying to disconnect, reconnecting and reconfiguring the
  external monitor, the display works correctly. However when turning off
  the Laptops LCD (via System>Preferences>Monitors) and leaving the
  external display on, then both display go back and no output is seen.
  The only way to fix is by changing to a tty and restarting GDM.
  
  Additionally I've seen other behavior such as been able to display on
  both screens, however, the resolutions were not correct and the windows
  were expanded between both screens (and incompletely in the external
  monitor).
  
  Other issue seen is right after connecting the monitor to the laptops
  VGA output, the screen changed to a console and displayed something like
  the following:
  
  [drm:intel_dp_aux_ch] *ERROR* dp_aux_ch not started status 0x8145003e
