I straced the hung X. There are lots of writev(31, [{"\241 _\275l\2 \1\331\1\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 527136}], 1) = -1 EAGAIN (Resource temporarily unavailable) in there - probably relevant?
@HDave: You don't have to reboot. Just Alt+PrtScrn , Ctrl+Alt+F1 , log in to the console, kill Xorg. ** Attachment added: "xorg.strace" http://launchpadlibrarian.net/14559186/xorg.strace -- compiz randomly freezes X https://bugs.launchpad.net/bugs/176589 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
