Public bug reported:
After suspend, my displayport-connected monitor will (most often) no
longer work at the native 1200x1080 resolution.
Restarting X fixes it.
This is not a new problem, but I always thought I had a wonky cable. I
only recently noticed the suspend issue, and only just now the restart
thing.
