Public bug reported:
The "Display" control panel shows a secondary screen on my laptop when
there is nothing connected to the HDMI or DisplayPort outputs. An
screenshot showing the problem is attached.
After "playing" with this screen, TTY doesn't work and the shutdown
process hangs before entering TTY.
I am using a MUXed hybrid graphics laptop (Intel Ironlake / AMD 5650m)
and this may be related to other problems I have with this system (bugs
#1162526 and #1163418).
