Found it! I removed my "Lock Screen" shortcut (Super + L) and it works. So this is still a bug.
The bug is: If you use the Super key in your Gnome keyboard shortcuts, you cannot use the Super key in your Compiz shortcuts. This is obviously wrong. -- Super key not working unless shift pressed on Toshiba Portege https://bugs.launchpad.net/bugs/408587 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
