Multi touch for any,all synaptics touchpad

Multi-touch became trendy after iphone came up with it. We are seeing many new laptops with multi-touch. At hardware level, there is nothing special that you need, to make multi-touch work. You can also do two-finger scroll and two-finger tap to right/middle click. Also, three-finger tap, but, for me it is very hard to press three fingers at the same time(1 out of 10).

Create new file

gksudo gedit /etc/hal/fdi/policy/11-x11-synaptics.fdi 

Paste the following code into the file and save it.

               synaptics        On        90        1        1        1        3          2          

Restart hal and enjoy multitouch touchpad.

sudo /etc/init.d/hal restart
