Disable touchpad in Ubuntu 11.04 (Natty Narwhal)



One of the most irritating things I have experienced in Ubuntu 11.04 was the inability to disable touchpad. Though my laptop has a hardware button to toggle touchpad, it never worked in Ubuntu.  When I was typing something, in most occasions an accidental touch of the touchpad caused the cursor to move somewhere else and part of the typed text ended up in nowhere.
But later I found this amazing little program called touchpad-indicator which can REALLY toggle touchpad status in Ubuntu. To install it use the following commands on terminal.

sudo add-apt-repository ppa:atareao/atareao
sudo apt-get update
sudo apt-get install touchpad-indicator

After the installation go to Applications -> Accessories -> Touchpad-Indicator and run the application (figure 1). It will create a launcher in the top panel. Click on it and select Preferences. Then set the desired options.

Don't forget to assign a keyboard shortcut (figure 2) before you finish editing preferences. Otherwise once you disable the touchpad, you won't be able to enable it unless you have a mouse connected to the computer.

 Hope this will be helpful !
