[ubuntu] How to find out what touchpad driver Im using?

view story

http://ubuntuforums.org – Im loving the touchpad driver that ubuntu is using! I have a natural, working 2 finger scroll, both horizontal and vertical with it. The reason Id like to know what driver it is is - my copy of windows 7 is using a synaptics driver, the latest. Its actually painful to use, very hit and miss with 2 finger scroll, and no option to right click using 2 fingers. So Im trying to find the same driver with the same functionality for my windows.
