It's a kernel problem, most likely the same as https://bugs.freedesktop.org/show_bug.cgi?id=81136. You should also see a GPU lockup if you suspend/resume without X running. Try booting with nouveau.nofbaccel=1, for me that helped. Cheers, Sven -- To UNSUBSCRIBE, email to debian-x-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
