Found it! I removed my "Lock Screen" shortcut (Super + L) and it works. So this is still a bug.

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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
