Hi

I can't really help you, but I thought I should add that for at least a
couple of months now there has been a roughly 50% chance that when I
boot my PC I will get exactly what you describe - a black screen with
only a mouse cursor - instead of the login screen.

I just press ctrl-alt-backspace twice to fix this...I think it restarts
the X server or something?  Anyway, it results in a working login screen
within a second.

Kind regards,
Huw
