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

Move windows control (min, max, close) button to the right

Worked from 12.04 - 13.10 (the original author said this, I tested on 13.10 and worked)

gsettings set org.gnome.desktop.wm.preferences button-layout ':minimize,maximize,close'
