Public bug reported: I have a "Happy Hacking" keyboard with 'meta' keys on it. Pressing the left meta key while running xev indicates that the key is mapped to keysym Meta_L (0xffe7). When I hold down this key and press the 'p' key, the display is wiped out. This appears to be some sort of broken video mode switching command, since the first press causes both monitors to go black, while subsequent presses seem to switch through various states of the windows being black, display mirroring turned out, reversed desktop assignments to monitors, etc. I have search through the system settings and the compiz configuration to try to find a shortcut that might be causing this, but have been unable to find it. When I accidentally press this key combination (which is often), it always ends up being the case that I will need to reboot my machine one or more times and suffer compiz crashes before I can get things back into a state where I can do useful work again.
In general, I would prefer to find a way to disable this broken feature and get the events passed through to the program, since I am able to use this key sequence in other versions of Ubuntu and have a very hard time remembering not to press these keys when working on my desktop machine.
