if you are using linux on a laptop you may have some questions like:
how do I tap with 2 finger to right click or 2 finger scroll
or how to tap to click instead of pressing the button.
all you have to do is edit the file 50-synaptics.conf from /usr/share/X11/xorg.conf.d
Section "InputClass"
        Identifier "touchpad catchall"
        Driver "synaptics"
        MatchIsTouchpad "on"
#this one for tap to click
	Option "TapButton1" "1"
#this one for two fingers to click
	Option "TapButton2" "3"
	Option "TapButton3" "2"
#this one for to fingers to scroll
	Option "VertTwoFingerScroll" "1"
EndSection
also if you want to revers the scroll, you can edit that on you system settings the input, mouse.
