Sorry for the spam, but this just happened again. This time I was dragging a Terminal window around which was running "top" while the machine was under load (load average between 4 and 5). I didn't cross monitors so that's probably a red herring.
Everything froze, but by switching to VT 1 and back (Ctrl-Alt-F1, Ctrl- Alt-F7) I was able to regain control by relaunching unity with LIBGL_ALWAYS_SOFTWARE=1 from that window. I am sure I didn't have this problem just a week or two ago, sorry I can't be more specific other than that I am running 13.04. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/932900 Title: Unity freeze, crashes when trying to restart - GPU lockup with IPEHR: 0x7a000002 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/932900/+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
