HowTo - Enable Logitech mouse wheel in Slackware 9.1

[SlowCoder]

In hopes of helping other who might have the same type of config as me ...

For some time now I've not been able to get my Logitech wheel mouse (PS/2) wheel to work on Slackware 9.1.
I wasn't able to directly find information pertaining to my mouse and OS, so I did a little playing (logic use of other configs).

Here's what I did:

In the /etc/X11/XF86Config file (in the mouse (Core Pointer's Input Device section)):

Uncommented the following line
Option "Protocol" "Auto"
Added the following line
Option "ZAxisMapping" "4 5"

Just to elaborate for those with this trouble.

the settings need to go in your X config file often called something like /etc/X11/XF86Config

you locate the section for you mouse and make sure it has the Zaxis setting. A snippet from my config is shown below.

Section "InputDevice"
	Identifier  "Mouse0"
	Driver      "mouse"
	Option	    "Protocol" "IMPS/2"
	Option	    "Device" "/dev/psaux"
	Option	    "ZAxisMapping" "4 5"
	Option	    "Emulate3Buttons" "no"
EndSection

Always nice to see posts that give help!
