If right click dont work go to and open

/etc/x11/xorg.conf

copy:

	Option "ClickPad"         "true" 
        Option "SoftButtonAreas"  "50% 0 82% 0 0 0 0 0"
EndSection
----------------------
paste it in right under Option "SHMConfig" "on" so that it look like this:

Section "InputDevice"
	Identifier "Synaptics Mouse"
	Driver "synaptics"
	Option "SHMConfig" "on"
	Option "ClickPad"         "true" 
    Option "SoftButtonAreas"  "50% 0 82% 0 0 0 0 0"
EndSection

save - retstart X - right click works :-)
