Definitive guide to disabling the touchpad / trackpad on Ubuntu 9.10 Karmic Koala (UI based, easy)

After reading several guides and forums about disabling the trackpad on Ubuntu 9.10, I finally figured out the magic combination. And there are no command line steps whatsoever - just System->Preferences choices.

The quick background:

Ubuntu has two System -> Preferences apps that affect the trackpad: Mouse and Touchpad. The Mouse app has a Touchpad tab with a "Disable touchpad while typing" option. The Touchpad app has an "Enable Touchpad" option on it's main tab. Apparently, if you check both, the Mouse app will detect when you are done typing and re-enable the touchpad!

Instructions:
1. Open System -> Preferences -> Mouse

2. Select the Touchpad Tab

3. Deselect (turn off) the "Disable touchpad while typing" option

4. Open System -> Preferences -> Touchpad

5. Deselect (turn off) the "Enable Touchpad" Tab

That's it!

Enjoy your laptop :)
