Disable touchpad for laptop

I got problem with my touchpad.. it let the cursor jumping here and there .. so it's very annoying.

Here is the tips that I found out from the Internet

xinput list | perl -ne 'if ($_ =~ /Synaptics/) {exec "xinput","set-prop",substr($_,3+index($_,"id="),2),"Device Enabled","0"}'

You may change /Synaptics/ with any value that pointed to your device from "xinput list" command
