Scroll con 2 dedos en Samsung N220+

For multitouch in touchpad, I created a script and added at startup (system-->preferences-->aplication at starup or similar, I'm using spanish version). It works fine for multitouch.
You can find more info in many forums about this script.
I think that you have to enable Visual Asistance for it works

#!/bin/bash
# enable multitouch
sleep 5
synclient VertTwoFingerScroll=1
synclient HorizTwoFingerScroll=1
synclient EmulateTwoFingerMinW=5
synclient EmulateTwoFingerMinZ=48
