Public bug reported:
When undocking the Lenovo Thinkpad T440s from a dock with an external
monitor, all the screens move to the laptop display. When I redock the
laptop, all the screens stay on the laptop display and the monitor
configurations don't reset. The laptop display is still marked as the
main display and is on the wrong side of the other monitor from where
it's physically located. I have to either restart the machine to have
the display settings return to the way they were, or reapply them by
hand.
