Unfortunately, in my case xrandr does not refresh its state. I left my laptop 
connected for more than a minute, but it was still reporting "home settings", 
not the ones, it really should see at work. I had to un-dock it and re-dock it 
while it was on, then xrandr started reporting proper outputs and modes.

So I need a way to generate undock/dock event by software.
