Started my workstation today, logged in, launched startx: mouse was dead,
pointer just sat inactive in the middle of the screen.

I have seen a couple of desktops that every once in a while would not
recognize a PS2 mouse. On both of them rebooting always 'fixed' it.
One of them I found out by accident that it was related to how many
items were plugged into the USB ports. Weird I know, I guessed at the
time that the PS2 ports must use the same power bus that the USB did,
and total power required was causing brown outs so to speak.
The other one seemed to be fixed by a BIOS update.
Of course a bad mouse is possible too...

I wouldn't be too quick to blame X on this one - otherwise wouldn't
logging in and out fix it since you indicated to startx manually?

Yes, I restarted X a couple of times but it made no difference.

So, looks like it is down to sunspot activity.

Is there no other way to kick start the mouse again than a reboot? I tried
reloading the psmouse module but it had no effect.

Curiously the video signal from another one of my boxes has died - the only
connection is that they use the same KVM switch. However a reboot did not fix it
and connecting my monitor direct to the VGA card proved that there's no signal
coming out of it.

Hmmm. Must have been some major solar flare.
