[olug] Debian forgets my mouse

I'll second JohnH's idea for a reboot - PS/2 hot-plugging is flaky and prone
to hardware errors. :-(

If you can't do that, or it doesn't work, what happens if you run "cat
/dev/psaux" and then move the mouse?  When you do that as root you will get
a lot of jibberish each time the mouse is moved.

If you don't get the output, then it could be the drive (or mouse or PS/2
port or...).  Try running the same test command on the various /dev/input/*
devices (mice, mouse0, mouse1,...) and see if any of those work.

If you do get the jibberish output from one of those devices, it could be
the X11 config got munged and the mouse section was changed.  Most X11
configurations use "/dev/input/mice" rather than "/dev/psaux" since the
"mice" option combines all mice devices into a single unified device access
point.  Look for that section of the /etc/X11/xorg.conf and post it to the
mailing list (please, not the entire xorg.conf file).
