On Lenovo Thinkpad X201 with docking station with two external monitors, one on VGA, one on displayport effect is generally that the screen being left just flickers slightly.
I have had the screen go black with flickering pixels on the side and thought it was when crossing over slowly but just tried to replicate and can't so more rare in my case. Fresh 16.04 install yesterday (was on 14.04 with no issue).
