X issue? No mouse cursor in between sessions (sometimes).


I have a regular optical USB mouse conected to PS/2. Occasionaly i
come home to the gdm login screen, turn on the monitor and discover i
have no mouse cursor. I can login and do whatever i want, the mouse is
there and works, but i see no pointer.

I've tried issuing kill -HUP to both gdm (two instances?) and Xorg as
well as killing them both and restarting gdm. There's a process called
kpsmoused i can't seem to kill. So far the only "solution" i've found
is the rather unelegant reboot. I mostly use fluxbox but i don't think
that's relevant and i believe that it has happened with gnome as well.
There's no particular pattern i can follow to duplicate this, i log
in/out all the time. I last ran apt-get dist-upgrade a few days ago
but this particular issue still persists and, if i remember right, it
happens not only in between sessions but during a session as well.

Here's some useful info:

Is the SMP for multiprocessor? 'Cos i only have one... I also don't
have Bluetooth but that shows up on my dmesg.
