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".
