While testing I noticed a couple of things:

While everything the GUI is the correct resolution, GNOME is unable to
identify the monitor vendor or model. This is a regression from the
previous edid override functionality. It looks like this is because the
edid file in /sys is not populated with the EDID override data.

I got a crash due to null pointer dereference at one point, I'll try to
track down when this happens.
