First off does the touch-pad support two finger scrolling? If so the result of synclient -l
would be nice to edit
add the output of the command synclient -l.

You can change the setting of the synclient by adding to the startup application a new application with the following command:
xterm -e synclient "EmulateTwoFingerMinZ=10"
This would change the setting of EmulateTwoFingerMinZ to the value of 10
