A similiar thing is happening to me on my Dell e6400 running 8.10. It only seems to happen when I'm running a dual head display. When I'm at home, with only the laptop display (i.e. now) I can't make it happen.
I find occasionally (mostly when running a virtualbox vm and clicking the hot key to leave the vm and when running vnc to a remote machine and then returning to my host with the mouse.
When it happens, I can move the mouse, but clicking it does nothing. I can alt-tab to go between windows, and can use the keyboard. I haven't tried the control-alt-f1 - will do so tomorrow. When it happens, I do a control-alt-backspace and log in again (most annoying!).
