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 Bugs, which is subscribed to 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 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
