On the same system where I experienced bug 899501, I've updated the system to a later Factory build and can now no longer activate my external display at all.

Though xrandr reports: Screen 0: minimum 8 x 8, current 1920 x 1200, maximum 32767 x 32767 eDP1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 309mm x 175mm 1920x1080 60.01*+ 1400x1050 59.98 1280x1024 60.02 1280x960 60.00 1024x768 60.00 800x600 60.32 56.25 640x480 59.94 DP1 disconnected (normal left inverted right x axis y axis) DP2 disconnected (normal left inverted right x axis y axis) DP3 disconnected (normal left inverted right x axis y axis) DP4 connected 1920x1200+0+0 (normal left inverted right x axis y axis) 546mm x 352mm 1920x1200 59.95*+ 1920x1080 59.99 1600x1200 60.00 1680x1050 59.95 1280x1024 60.02 1440x900 59.89 1280x960 60.00 1024x768 60.00 800x600 60.32 640x480 60.00 DP5 disconnected (normal left inverted right x axis y axis)

The output on DP4 is black, and the monitor does not detect a signal.
