The Scroll Mouse Page

I've used a M$ Intellimouse for several years now and never tried to get the scroll to work
in Linux. For some unknown reason I've always assumed that if the scroll wheel didn't work,
I wasn't going to spend any time on it. Today I decided I would do a search on the forum
at linuxjunior.org and see if anyone had gotten one to work. I was in luck and found that
most generally you only need to edit one or two lines in XF86Config to do it. First, your
mouse driver must support it. PS/2 and msmouse won't do it, but the Intellimouse (IMPS/2) will.
So I changed "Protocol". The next change, was emulating 3 buttons will mess up the wheel,
so I commented out (or removed) those options. Finally, you have to add a "ZAxisMapping",
so I added it and mapped it to "4 5". I saved the file and restarted my X-Server (Ctrl-Alt-Bksp)
and magically the scroll wheel worked perfect. A sample of my XF86Config is:

********************** START OF SECTION ***********************************************

Thanks to my friends at http://www.linuxjunior.org for this fix!
