For those who want their touch pad enabled with tapping there is a very simple method, something that just slipped my eye. It is so simple that makes me want to kick my self. Just click on System menu -> Preferences -> Mouse. Clicking on the Touchpad tab should open a window as below:
Well then just enable your choice by ticking the options and you have them by default.
But this will not work on KDE or at login. To do so copy
/usr/share/hal/fdi/policy/20thirdparty/10-synaptics.fdi to /etc/hal/fdi/policy
and edit the file according to your needs.
<merge key="input.x11_options.TapButton1" type="string">1</merge> <merge key="input.x11_options.TapButton2" type="string">3</merge> <merge key="input.x11_options.TapButton3" type="string">2</merge>
Add the above lines if they are not present. This will enable tapping, two-finger tap for right click and three for middle click.
