It happened another time, so now I have the output from avivotool during a lockup
as an update, it does seem to occur in clusters (twice today) This time, only chrome was open, but I was working in gnome-terminal when this happened. ** Attachment added: "output from avivotool during a lockup" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1023916/+attachment/3221364/+files/regdump_bad.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1023916 Title: Xorg freeze To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1023916/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
