If your problem has been solved, please let us know.
Agree it is important to finish off threads - you search for things and the thread comes to no conclusion, upsetting.
What prompted the mouse stopping at the black screen was putting the laptop into suspend mode, with Fn+suspend (Dell Inspiron 4000). Other things may do it too, but this is the one I've spotted.
According to ps and top gmp, the general purpose mouse daemon, has stopped.
fsateler's receipe gets it working again. But do it twice: first time it claims to have stopped and then restarted gmp - odd since it was not running. But the mouse does not work. Repeat the command and it says gpm is not running and it has started gpm, then the mouse works.
(Incidently if the mouse stops in X just switch to a terminal with ctrl+alt+F1/6 and then switch back with alt+F7).
