I downloaded the current trusty image, Live OS had same problem, Installed OS had same problem.
I updated mainline kernel and had similar problem. The screen came back corrupted for 1/2 a second, then it went to a black screen with a mouse cursor (movable), so the recent changes are doing something different, but not what I need, even if it would restart the GUI session if it times out (stops responding) instead of locking up/giving up on the x session, I could live with that. I was unable to get it to re-start a new x session using ctrl+alt + F1 and typing startx like I could with previous tests. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1224221 Title: 10de:1244 [Asus MAXIMUS IV GENE-Z] Nouveau Sleep/Wake problem in Ubuntu 13.04+ To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1224221/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
