Hi Board,
I have an Optical Logitech Scroll mouse connected to my PC through the PS/2 port. The scoll feature works fine in windows but hardly works in Linux. I use Red Har 8.0 with Bluecurve desktop. Anyone got any suggestions????

Hardly works? If it doesn't work at all, you may need to change the protocol in /etc/X11/XF86Config-4 to suit your mouse. I have a wheel mouse and the protocal ImPS works fine.
If this isn't the problem, then you'll need to post more about what you mean by "hardly working"

Perhaps you can help me on similar issue. I am running a RH9.0 under Vmware 4.0.2 on a Win2k SP3 box with a Logitech MX700 optical (8 buttons + wheel) on PS2 (actually usb to the windows host box). Vmware tools rewrites the XF86Config-4 as follows:

Section "InputDevice"

# Option "Emulate3Timeout" "50"
# Option "ChordMiddle"
Identifier "Mouse1"
Driver "mouse"
Option "Protocol" "IMPS/2"
Option "Device" "/dev/psaux"
Option "ZAxisMapping" "4 5"
# Option "Emulate3Buttons"
EndSection

Somewhere I found that I could edit this to, at a minimum, include the wheel functionality. Perhaps you could look at yours and let me know if and how it differs. Using GUI KDE or Gnome tools doesn't seem to recognise the Vmware modified file.

Thanks - I will forward points if you can help

Hmm. I'm at work at the moment, so I don't have my XF86Config-4 to hand, but I'm pretty sure that to get the scroll wheel to work, I enabled the IMPS/2 protocol and set the ZAxisMapping, just as yours is. The only difference that I could think of is that the identifier for mine was "Mouse0". I would perhaps check that you don't have another mouse definition, and maybe try commenting it out, although to be honest this shouldn't really make a difference, as long as you mouse is on /dev/psaux, which it should be if it's a PS/2 device.
See if you have another mouse defined and post the output if you do. Also, post the output of:
"ls -l /dev/psaux"
although I very much doubt that this is a problem.
Sorry, I couldn't be of more help

Here is a section of the /etc/X11/XF86Config-4 file on my machine
How do I get the scroll feature of my mouse working

Section "InputDevice"
Identifier "Mouse1"
Driver "mouse"
Option "Device" "/dev/input/mice"
Option "Protocol" "IMPS/2"
Option "Emulate3Buttons" "no"
Option "ZAxisMapping" "4 5"
EndSection

thanks for your reponse
FYI the return of: ls -l /dev/psaux is:

crw------- 1 root root 10, 1 Nov 10 22:19 /dev/psaux

I would note that the file size is 0 bytes. ditto for /dev/mouse.

I can't find any references to Mouse0 in any of my X86Config* files

In reply to both of your question, I'm afraid I can't help. I'm pretty sure my mouse is set up in exactly the same way and it works fine. I'll check when I get home, and post if there's any difference, but as far I as know, your configs should work.
Sorry
