Comment 57 for bug 1288572

re #50, that is showing 2 modesetting providers but there should only be one. something odd is going on there (unrelated to the mutter update), also gdm is not expected to work until I patch it.

CRT-0 is usually an external monitor, LVDS are generally the builtin LCD panels. This part of the story sounds like a nvidia bug, but would be interesting to see what xrandr -q says
