Hello everybody... The above script allowed me to use happily multitouch for a month... Now if I do a two fingers scrolling the mouse cursor just runs on the screen like possessed... Any hints?

It took me AGES but I'm really glad to share the solution.

On this page: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/308191/+index?comments=all

you can find comment 116 where with a click you download and then install this:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/308191/+attachment/1735234/+files/synaptics-dkms_1.0.0_all.deb

After installing just go to

System ---> Preferences ---> Mouse

Then click on Touchpad tab

and finally click on Two fingers scrolling.

YAY! :D
