MouseWheel in Linux

In my XF86Config file I have

Option "ZAxisMapping" "4 5"

Set in the section where my mouse is... Isn't this the right line to set up mouse wheel scrolling?

Gentoo Linux
2.4.25 Kernel
Fluxbox 1.14

Noobs dont use linux.

Try www.linuxforums.org

They helped me a lot when I was starting out.

I didn't visit the site, but apparently changing the protocol to Logitech instead of PS/2 worked :P
