So, everyone loves the new Ubuntu 14.04 lock screen, which looks exactly as the login screen.
But there is an issue with it. If you lock your screen manually (Ctrl + Alt + L) and leave your computer a couple of minutes (untill it locks the screen automatically), when you unlock it, it will ask for your password twice.
Workaround: Go to Settings -> Brightness and Lock -> Lock [OFF] (switch it to off).
