https://bugs.freedesktop.org/show_bug.cgi?id=91333 --- Comment #10 from Ilia Mirkin --- A few people who have had these PDISP errors were due to gnome toggling cursor state when a CRTC had not been enabled, and nouveau not properly protecting against it. There was a (lost) patch that fixed it, unfortunately I don't remember where the place was. Ben should be able to come up with that patch fairly easily. However for the user in question, while the PDISP error dumps went away, the underlying problems remained. Just a thought. [As an aside, Corey, with reverse-prime you should also be able to get all 3 screens up... see http://nouveau.freedesktop.org/wiki/Optimus/ . Of course nothing is perfect, this also introduces tons of problem for some people. But not others.] -- You are receiving this mail because: You are the assignee for the bug.
