Disable Touchpad on Gnome

It's annoying when you typing some thing suddenly your pointer fly-away somewhere else coz you inadvertently touch the touch-pad with part of your hand.

There are two way to disable/enable thouchpad in Gnome :
1. Go to menu on "System" -> "Preferences" -> "Mouse"
Click on "Touchpad" tab and [un]check "enable Touchpad" below "General" section.

2. Open Terminal [Command line box / console].
To disable, execute :

gconftool -t bool -s /desktop/gnome/peripherals/mouse/touchpad_enabled "f"

To enable, execute :

gconftool -t bool -s /desktop/gnome/peripherals/mouse/touchpad_enabled "t"
