Note that the compiz process appears to be zombie, and "kill -9" naturally fails to make it go away. I suppose it might be racking up all this time attempting to dump core.
I wish I knew whether compiz has been berserk in all the cases where I power cycled the system to regain control. If it has, the implication seems to be that this is a Unity bug. Otherwise not. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1680502 Title: Hang after upgrade to 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1680502/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
