I have been able to reproduce that a few times in a gnome-shell session but it's not specific to any one task. It "crashed/froze" twice just looking for logs and once again while launching Firefox. OTOH I can use the classic session w/o a problem - in fact I'm streaming the nightly news right now.
I know that X actually freezes when the screen tears because I'd set Ctrl+Alt+Backspace to kill X and tested it in both sessions. When the screen tears as shown in the attached pic the keyboard is just totally unresponsive causing me to do a hard reset. There are no .xsession-errors in Home and I don't see anything unusual in /var/log/Xorg.0.log but there is also an /var/log/Xorg.0.log.old that I can't read. FYI sometime tomorrow I'll add some storage to that box so I can retain 4 or 5 installs at the same time. That way I can dig for logs and/or do some retesting without having to reinstall and update each time. ** Attachment added: "IMG_4817.JPG" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau/+bug/1412602/+attachment/4314052/+files/IMG_4817.JPG -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1412602 Title: No live DE in Vivid using nouveau w/GeForce 7025/nForce 630a To manage notifications about this bug go to: https://bugs.launchpad.net/nouveau/+bug/1412602/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
