I'm the original reporter of bug 48518. That is the description of my problem (on Ubuntu 12.04):
I was working on an external monitor with my notebook. I changed the monitor settings to turn off the external monitor and turn on the notebook integrated monitor. When I applied the changes something went wrong: I couldn't see anything. Then I replugged the VGA cable for the external monitor and something appeared again, but it was all working strange and not as it should. Unfortunately I was working and I had to restart the computer; anyway nearly nothing worked: it was just a miracle that I managed to report the bug. I couldn't even open a terminal, I don't think I would have managed to take a screenshot. Neither I had a camera at hand to take a photo. I'll do my best to describe what I saw: - no launcher appearing when approching the left screen side - no panel (the top bar) - all the windows (which were already open) overlapping and cut - clicking on a window didn't cause it to appear on the foreground, but I was able to interact with the application program (write, click buttons) - no keyboard shortcut worked (at least not visibly); I tried using these: CTRL-ALT-T (to open a Terminal), Windows button (to open the Dash), ALT-F4 (to close windows) - I was able to drag the windows I didn't think about this when it happened: maybe even if I was "blind" everything was working and I could take a screenshot. Anyway it's too late and I'm still not sure I could. For further details please refer to "https://bugs.freedesktop.org/show_bug.cgi?id=48518"; and the original Ubuntu bug report. If somehow I can help you, please let me know.
