I had this problem before installing Cairo Dock. Even with Cairo Dock installed, this problem did not get worse or better.
I have also noticed that my laptop (same system for this report) halts instead of pwoering off. sudo shutdown -P now # I later find the system suspended, but not powered off. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1242907 Title: The Shutdown button does not work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1242907/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
