Apple Magic Trackpad aftrer upgrade from Ubuntu 11.10 to Ubuntu 12.04 (64 Bit) - Multitouch not working!

To get this working I had to install utouch:

apt-get install utouch

I was able to enable two-finger scroll by using the xinput command. xinput with no arguments shows all the input devices on the system. The Apple Trackpad was device 9 in my list; I used command xinput list-props 9 to see all the properties for the Apple Trackpad. I then disabled the edge scroll using the Mouse and Touchpad menu in System Settings, then enabled two-finger scrolling (282) using xinput.

xinput set-prop 9 282 1 1

The change is NOT reflected in the System Settings --> Mouse and Touchpad settings, but everything now works.
