Bug Description
Problem:
Connecting a display through the display port does nothing. I can try to press the key combo fn + f7 or trigger the monitor to refresh and the display is still blank on the external monitor.
udev does not seem to notice the display port connection either.
Expected result: External display should be mirrored when inserting a display port or VGA connection.
