newbie: IBM TP R40 - spastic UltraNav, though USB mouse works fine - RH 9.0

I am encountering a frustrating issue on a dual boot (XP & RH 9) system.
Once again, this is an IBM ThinkPad R40.

As I recall, during original install of RH 9, the internal pointing
devices (both stick and touchpad) worked. Upon first boot, however, both
internal pointing devices stopped working. The cursor can be moved by
the touchpad, but it keeps snapping back to lower left corner.
Attempting to use the stick yields mcuh the same results, with the
addition of what seems to be interpreted as random clicks all over the
screen - menus come and go, etc.

This behavior is not only present in X, but also in text tty sessions.
(OK, no menus popping up in the consoles, but random marking of screen
regions occurs).

An external USB mouse works fine. All behaves properly in XP.

I have been unable to find any info on this - seems that those that have
similar machines have not encountered this problem.

Tried updating through Red Hat Network to possibly solve the problem -
no joy. New kernel, same behavior.

Can anyone suggest some things to try?

If you played around with the bios settings for them,
set them back to the defaults.

Read up on gpm. Verify it is correctly configured on
your system. Mine is running as:

gpm -t ps/2 -m /dev/mouse

Go to: Red Hat button | System Settings | Mouse
Select 3 Button Mouse (PS/2)
OK

Only settings are [disable|automatic] for touchpad and joystick. Both
set to automatic.


Is this for console screens only? Hard to tell from the man page.
Nevertheless...


...Thanx - this worked. I was set to MS Scroll mouse. After setting to
generic 3 button PS/2* the unit now works.

*(and reboot - any way I could have gotten around rebooting?)

For the next layer of the onion, the UltraNav does some extra things in
WinXP. I have it set up so the touchpad does nothing, save for emulate
the scroll wheel on a scroll mouse - in only the center region of the
touchpad. Also, the buttons associated with the touchpad invoke PageUp
and PageDown, rather than LeftButton and RightButton. I would like to
have the same functionality in linux. Do you have a recommendation as to
what to read to enable this functionality? Or is this a non-starter?

Thanx,
Joe

Glad one of those suggestions worked. I haven't had the problem
you described on my T40p, so was guessing.



Probably doesn't do what you want yet, but you
might want to play with tpctl
ThinkPad configuration tools for Linux
http://www.yqcomputer.com/

Perhaps you can extend it (or provide the author
of it with useful info on the UltraNav).

Looks most intriguing - thanx for the pointer.
