Always wanted this feature but it never works in ubuntu. Is there any hack/mod to get it to work? My laptop is an Acer 5532, and my touchpad is from Synaptics. The latest drivers from Synaptics made two-finger scolling possible with Windos 7, so I'm guessing there's some way to work in Ubuntu/Linux.
So I guess you enabled the two finger scrolling as described in my first answer. As you cannot post the results of synclient -l try the following:
Open start up applications and add a new application and write the following command into the command line
xterm -e synclient "EmulateTwoFingerMinZ=10"
this will change the most probably too high value in synclient.
Did you try to change the settings of the mouse in the control center?
If it still does not work, run
synclient -l in the terminal and provide us the results.
Touchpads explicitely need to support multi finger gestures. If you do not have such a touchpad, you are out of luck.
That's all to say without more information about your touchpad.
