Then choose the Layouts tab. Click the "Add" button. Then Change the country to India and choose your tamil layouts. For myself i choose "India Tamil Unicode"

You can change your typing language using the keyboard layout on the top panel. By clicking on this applet you can change the language layout what ever you want.
