Title:
  external monitor no longer works

Status in “linux” package in Ubuntu:
  Invalid

Bug description:
  I updated my system, a Lenovo X220, this morning.  Upon rebooting, the
  external monitor would not work.  It flickers a lot of mainly-green
  gibberish, and it is unusable.  The internal LCD screen in the
  notebook still works, but not when the external monitor is connected.
  The external monitor is a Samsung 1920x1600.  I rebooted the machine
  again, this time selecting Linux 2.6.38-11.  Now the external monitor
  works properly, just as it used to.  Upgrading the Linux from -11 to
  -12 is clearly what broke the system.
