The changes to XF86Config must also be made to /etc/X11/XF86Config-4 (as root) if you are using the default (later) version of XFree86 (4.x). The following line should be entered exactly as below (with the quotation marks) at the bottom of the section
Code:
Section "Input Device"
Option "ZAxisMapping" "4 5" (as mentioned in the earlier post - thanks! this fixed it for me
)
Then logout of your session (the Window Manager needs to restart), and log back in again.
TaDAAAAA!
Kewl, no?
Hope this does it for you as it did for me.
