I thought all linux users knew this but my "so called Linux God" buddy came over the other day he was freaking out cause I am able to use my
scroll function on my mouse...so I thought maybe someone else could use this info.
It's really simple if you have a mouse wheel that can
scroll then edit your
/etc/X11/XF86Config or /etc/X11/XF86Config-4 depending on which one you have and edit the line Protocol ps/2 to imps/2
Option "Device" "/dev/mouse"
Option "Protocol" "imps/2"
This should work just fine however if you run into trouble here is the web page that helped me out long ago.
