Bug Description
I'm running Ubuntu on a laptop (nominal resolution 1440x900) with another monitor connected (1920x1080).
The laptop display is broken, and I only use the other monitor.
It seems that ligthdm uses the laptop native resolution (1440x900) instead of the monitor native resolution (1920x1080).
As long as possible, lightdm should use native resolution for each screen.
Side effect: once logged in, the correct resolution is applied (laptop display -> disabled, external monitor -> 1920x1080), but the transition causes an artifact: after the resolution is set to 1920x1080, but before the wallpaper is displayed, the lightdm background get tiled to cover the whole screen surface, which looks strange.
