I can now reproduce this from within the session.

* Starting point - everything is displaying as expected.
* Open System Settings/Display Configuration
* Disable the secondary monitor and click Apply
* Enable the secondary monitor (this will have reverted to landscape mode) and click Apply
* -> The monitor should now display the desktop as normal (although in the wrong orientation in my case)
* Click on "90 degrees anticlockwise" orientation, then click Apply
* -> The monitor will be black, with a visible mouse cursor

The same behaviour is shown going from no rotation to 90 degrees
clockwise, or from 180 degrees rotation to either of the portrait
orientations, but it works fine going from no rotation to 180 degrees.
