Hangs like this have been happeneing randomly for me, since the 12.04 release. Again, the hang is mostly screen freezes, except for mouse. Sometimes, it locks the keyboard out, as well. And I have to use Sys-rq to reboot.
Finally decided to report it. :) I have attached the output from that script. Might go and try the nvidia drivers, but support was awful for my card in previous releases. ** Attachment added: "Output from /usr/share/bug/xserver-xorg-core/script 3>&1" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau/+bug/994306/+attachment/3436432/+files/debug.out -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/994306 Title: [7025, 7300 GS, 7900 GS] Intermittent GUI hangs in 12.04 Status in Accelerated Xorg driver for nVidia cards: Incomplete Status in “xserver-xorg-video-nouveau” package in Ubuntu: Confirmed Bug description: I have upgraded to 12.04 two days ago and since then, the GUI has hung 4-5 times (a couple times a day basically). I'm running Gnome3 (not Unity) Here is a forum post which describes what happened and what I have done: http://askubuntu.com/questions/130803/12-04-gui-hangs I don't use much, only Eclipse, Chrome and terminal windows. Skype and Pidgeon are running as well. The hangs have happened in the middle of using Eclipse or typing into a terminal window. Prior to the upgrade (I was on 11.10) I had no similar problems.
