Laptop is booted and logged in while undocked. Then once it's docked, no new
outputs are added to xrandr:

Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192

Followed lines are added to Xorg.log once docked (I've one display attached to
dock's DVI port):

If x11 is started after docking, xrandr shows both displays.
