Linuxien,
Your touchpad should be handled by
synaptics, it is different from the wired one.
Also, are you talking about right click or right tap? If the button, is it working on other distros? it could be broken too...
Maybe it's a synaptics issue, so you can play a bit with
synclient and read man pages of
synclient, synaptics, xorg.conf.
You can also look for informations in
/var/log/Xorg.0.log (or other Xorg logs if any) and search for
synaptics string. Maybe you'll find some errors or if all the functionalities have been correctly detected and their initial settings.
This is a boring issue anyone can fall into... you should do some work on your own

Bye.
