In 14.04, When I have an active session and lock screen via shortcut super-l, or Gear->"lock/switch account", the lock screen only shows my user with password.
To login as someone else, (my 5 year old likes to play minecraft while I am away), you have to click on the Gear->("Switch Account..." or a specific user) to be shown a list of users to login as.
Is there any way to change the default behavior so that when I lock screen, it goes right to the list of users, rather than only my user?
