Title:
  ligthdm does not use correct display resolution when two screen are
  connected

Status in “lightdm” package in Ubuntu:
  Confirmed

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.
