If compiz/unity is hanging then next time it happens, please switch to tty1 (Ctrl+Alt+F1) and run this: gdb /usr/bin/compiz `pidof compiz` | tee ~/gdblog.txt
Then in gdb, do this: thread 1 bt Now kill/restart compiz as before and attach the resulting file "gdblog.txt" (in your home directory) to this bug. Thanks in advance. ** Changed in: compiz (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/929655 Title: Unity randomly freezes after 11.10 upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/929655/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
