Well, it depends on what gets to the mouse first. If X gets to the mouse
first, then it'll be initialized as whatever XF86Config-4 has it set to.
If gpm gets to it first, it'll be initialized to whatever gpm.conf
thinks it is.
Anyways, I'm sure this is all very confusing, and it took me nearly a
month to figure out what was going on :) Basically, you *have* to make
sure that whatever gets to the mouse first initializes it to the highest
degree possible. The means using the protocol that most closely matches
what the mouse actually uses.

I had thought this ... but since 'gpm' and X were conflicting, I wasn't
sure. Are you using devfs with devfsd? Double-check the /dev/mouse is a
symlink to /dev/gpmdata. Using devfsd, changes arn't always kept over a
reboot.

Yup, I figured a reboot would fix it. :) It's that bloody initialization
thing. I don't think it's a problem with gpm and 2.4.x. I'm running
2.4.1-ac15, with devfs, but without devfsd and it works fine. I think
that if gpm.conf is set to use the imps2 protocol, it should work. Just
to humour me, try explicitly stating in /etc/X11/XF86Config-4 that X
should use /dev/gpmdata. Make sure 'gpm' starts at boot time, and
re-boot. If that doesn't work, feel free to contact me for more help :)
