Title:
  Moving external monitor around hard-locks x

Status in xorg-server package in Ubuntu:
  Confirmed
Status in xorg-server source package in Precise:
  Confirmed

Bug description:
  On a Lenovo Thinkpad X220:-

  1. Attach external screen to the displayport connector via HDMI adapter
  2. Boot the computer
  3. Login
  4. Observe all okay until running the display system settings applet and move the external display above (behind) the laptop display.

  X crashes to the point I have to use Alt+SysRq to reboot.

  I can run with the displays side-by-side but not one above the other.
  (my desk arrangement has the external display behind my laptop not
  side-by-side). I can recover the situation by moving
  ~/.config/monitors.xml out the way. I have attached my monitors.xml
  which may have some configuration issue causing the crash in X.
