Bug Description

Lightdm greeter (1.2.3 in xubuntu 14.04) used with xrandr (1.3.5) on dual monitor system (notebook intel graphics with external monitor) has bad-sized background on external monitor while the resolution is correct. It seems the background is same size as notebook's LCD.

xrandr is called: xrandr --output HDMI1 --primary --mode 1920x1200 --pos 0x0 --rotate normal --output LVDS1 --mode 1366x768 --pos 1920x432 --rotate normal

via greeter-setup-script in /usr/share/lightdm/lightdm.conf.d/70-xrandr.conf
