I can confirm the behavior mdo is experiencing. Super-L only seems to work for Lock Screen per session after you set it in the Hotkeys configuration. After a restart of the machine you have to reset the hotkey to Super+L again for it to work (and it will only work until you restart again).
I have also experienced the same exact behavior with Super+C, which I had set for Calculator. - Using Ubuntu 13.10 (Saucy). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/830709 Title: Keyboard shortcut - Unity should also use Super-L to lock screen by default To manage notifications about this bug go to: https://bugs.launchpad.net/ayatana-design/+bug/830709/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
