I'm working on a Panasonic Toughbook CF-C1 that also has this issue, though I can only rotate the display manually on this model (not sure by other thinkpad comments if it is implying an automatic screen rotation, perhaps by gyroscope, so I wanted to be sure to make the distinction just in case). Rotating it to normal, clockwise, counterclockwise gives no issue, 180 flip causes same black screen problem. Ctrl+Alt+F1 followed by Ctrl+Alt+F7 does fix this for me, though I'll note that switching back to Normal rotation after being on 180 rotation will cause the same black screen problem again, warranting another Ctrl+Alt+... etc. to return it to normal.

This has worked well until Kubuntu 14.10. Now it still works when I have an external screen (DP2) attached. I just tried it out now without an external screen attached. The screen turns black, but I can still see the mouse cursor. The cursor also changes according to the program that it is on, one just does not see the program. I can also click and it will have some effect. To see the screen again, I do [Ctrl][Alt][F1] and then [Ctrl][Alt][F7]. Somebody else has the same ThinkPad X220 with Ubuntu (not sure the version, though) but uses Unity. He has the exact same problem, so this is not bound to KDE or Unity, but fundamental to something that `xrandr` does.
