Public bug reported:
What I do:
Lenovo x250 is connected to Lenovo dock where an additional monitor is
connected. I only use the external.
Then I close the lid, take the laptop off the dock and use it a few minutes
later just fine.
Then I return back home, connect the laptop to the dock again with closed lid.
I press the dock's power button to wake it up. External monitor does not react.
When I open the lid, the internal monitor is on, I can not switch to the
external monitor in system settings, it is not detected in "xrandr --query".
