[Bug 655800] [NEW] External monitor connected via displayport is not recognized

 

Public bug reported:

Binary package hint: xserver-xorg-video-nouveau

After booting into Ubuntu without the cable plugged in, inserting the
cable and going to System > Preferences > Monitors and choosing "detect
monitors" does not detect the external monitor.

The same external monitor works properly if using the VGA connector.
