Hello. I'm having trouble configuring a generic optical wheel mouse in Linux 2.4.22 with Xfree86 ver. 4.3 and I hope someone here might have some tips.

It's an Inland Optical mouse 100 connected to the ps/2 port and none of the protocols seem to work for it. I do have a logitech three button non-optical model that works, so this is a second mouse, and I'll get rid of the logitech if I get it working.

I've tried the following protocols - auto, mouseman, ps/2, imps/2, with emulate 3 buttons both true and off.

It does send data when I move it:

bash-2.03# cat /dev/psaux
(ÿ(ÿ(ÿ(ÿ(þ(ÿ(ÿ?ÿ?ÿ?þ?ÿ?ÿ?ÿ?ÿ?ÿ?ÿ?ÿ8ÿÿ8ÿÿ(ÿ(ÿ(ÿ(ÿ(ÿ(þ(þ(þ(þ(?ÿ?ÿ

And here is my current XF86Config-4:

Section "InputDevice"
Identifier "Mouse0"
Driver "mouse"
Option "CorePointer"
Option "Device" "/dev/ttyS0"
Option "Protocol" "MouseMan"
Option "Emulate3Buttons" "true"
Option "ZAxisMapping" "4 5"
EndSection

Section "InputDevice"
Identifier "Mouse1"
Driver "mouse"
Option "AlwaysCore" "true"
Option "Device" "/dev/psaux"
Option "Protocol" "IMPS/2"
Option "Emulate3Buttons" "off"
Option "ZAxisMapping" "4 5"
EndSection

Section "ServerLayout"
Identifier "Default Layout"
Screen "Default Screen"
InputDevice "Generic Keyboard"
InputDevice "Mouse0"
InputDevice "Mouse1"
EndSection

Does anyone have any suggestions, or see anything wrong?

Thanks for any input!
Steve

Welcome to LQ.

Try commenting out (ie adding a # symbol to the beginning of the line) the entire Section for Mouse0, and remove it from the ServerLayout. Here's (a somewhat simplified) version of my XF86 entries:

Thank you. I like this forum - I've been finding a lot of good info here.

I made your edits and it works with the ps/2 protocol. I believe it should have worked before, but I just kept restarting X and I couldn't get anything to stick until I rebooted.

A tip to speed up an optical mouse is to add the option below to the InputDevice section.

Option "resolution" "1600"

Thanks again,
Steve
