Scroll on Slackware

As you already know, you can't scroll in Slackware by default, you have to set it by yourself (stupid, but life is a bitch).
Open your /etc/X11/xorg.conf file, and find Section "InputDevice" - Identifier "Mouse1". Edit the folowing with:

Section "InputDevice"

# Identifier and driver

Identifier "Mouse1"
Driver "mouse"
Option "Protocol" "IMPS/2"
Option "Device" "/dev/mouse"
Option "ZAxisMapping" "4 5"
Option "Buttons" "4"

And your mouse scroll will work.
P.S. Next to Option "Buttons" type how many buttons do you have, i have 4, so i typed "4"
