Comment 10 for bug 813566

On my laptop, the login is displayed on both the 1920x1080 laptop screen and the 1680x1050 external display-port monitor for about half a second. Then both screens abruptly go blank, and shortly afterwards the login reappears on the laptop monitor. It doesn't matter if I'm typing the password at this point (the characters are not lost or anything). It's just rather disconcerting.

The laptop screen is sized correctly to the native resolution with the latest lightdm - before it was being resized to the 1680x1050, like the external monitor.
