How to disable laptop’s touchpad in Linux?

I just want to share something that might come to your helps. If you are using Linux on your laptop and don’t want to use the touch pad, please follow this:

1. Open file /etc/X11/xorg.conf and find a block similar to:

Section “InputDevice”
Identifier  “Synaptics”
Driver      “synaptics”
Option        “Device” “/dev/input/mice”
Option        “Protocol” “auto-dev”
Option        “Emulate3Buttons” “yes”
EndSection

2. Add a line (an option actually) before the “EndSection”:

Option      “Touchpad Off” “1″

So the section now should look like:

Section “InputDevice”
Identifier  “Synaptics”
Driver      “synaptics”
Option        “Device” “/dev/input/mice”
Option        “Protocol” “auto-dev”
Option        “Emulate3Buttons” “yes”
Option        “Touchpad Off” “1″
EndSection

3. Save the file, logout and login.

Your touch pad should no longer be active. I tested this in my Fedora Core 8.

Thanks.
