My laptop has a Synaptics touchpad with multi-touch support. Kinetic two-finger scrolling works fine on windows, how can I get it to work on ubuntu?

I have already reversed the scrolling direction by editing the `/usr/share/xorg.conf.d/50-synaptics.conf`, all I need now is to give it some inertia.

I am using the 32 bit version of Ubuntu 12.04 LTS

This [link](http://manpages.ubuntu.com/manpages/precise/man4/synaptics.4.html) explains a lot about the different parameters, but I can't seem to find the right parameters to set in order to achieve this. Please do not answer unless you have tried this before. Thank you :)
