Bug Description
The screen lock in LightDM may be bypassed on a laptop using an external display, keyboard and mouse.
Steps to reproduce:
* Suspend the laptop
* Connect an external display, keyboard and mouse
* Wake up the computer by opening and closing the lid (I had to do this a couple of times) and moving the mouse about after the lid is closed
* You are now logged to the Ubuntu desktop, without entering the password
Expected behaviour:
* A password prompt should appear on the external display after the lid is closed
Please tell me if there is more info I should provide.
