Public bug reported:

Binary package hint: xserver-xorg-video-intel

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:
