mouse wheel in slackware 12.2

As root edit /etc/X11/xorg.conf for slackware 12. The syntax of the file is the same for both.

Find the 'Core Pointer' section. In there you will have something like this:

Identifier "Mouse1"
Driver "mouse"
Option "Protocol" "IMPS/2"
Option "Device" "/dev/mouse"


Protocol and device might be different on yours if, for example, you have a USB mouse.

Add two lines here to make it look like this:

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


Restart the X server.

Enjoy abusing your wheel :)
