Title:
  [Regression] gnome control centre does not allow you to disable the
  laptop screen while leaving an external connected screen working

Status in GNOME Control Center:
  New
Status in “gnome-control-center” package in Ubuntu:
  Confirmed
Status in Fedora:
  Unknown

Bug description:
  Lenovo T500 with displayport has a 1920x1200 monitor attached, I use
  the displayport in a similar way to a docking station in that I attach
  the monitor with a displayport to dvi cable, and then expect to be
  able to switch off the laptops internal display, only leaving the
  external monitor working.

  Screen detection works fine, mirrored screen works fine, but disabling
  the internal display and activating the external display just leads to
  the screen going black until the timeout has been reached, whereupon
  it reverts to its previous setting.

  This is a fully updated oneiric install
