OK folks i have crawled all over this site and a few others :P From what i have found i have to add the line
Option "ZAxisMapping" "4 5" #### for the wheel
to my xf86config to enable the wheel .
My problem is when i do this it gives me an error stating the the option "4 5" is invalid for this field . The most is a simple ps wheel mouse , to be exact a microsoft intillimouse. Any body have any thoughts ? Lack of the wheel is starting to drive me mad
