x.org issues

so i installed x.org, it went fine, except my mouse wheel doesnt work. since i use fluxbox, this gets quite irritating. i'd appreciate any help.

here's the relevant part of xorg.conf

Section "InputDevice"

# Identifier and driver

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