So apparently Gnome has changed the default shortcut for Lock screen to
Super+L. That's fine by me, but I want to disable it and replace it with something else.
So I open the Keyboard->Shortcuts->System settings, where it claims that Ctrl+Alt+L is bound to locking screen. But when I press Super+L, I still get locked.
I then reassigned Super+L to Typing->Switch to next source. But I still get locked out on Super+L! Why is this and what to I do about it?
