On the site: https://wiki.ubuntu.com/Multitouch
It says that unity supports 3 finger pinch to maximize/restore windows and many more gestures.
I am not able to use these multi touch features. I can only use two finger scrolling and nothing else. My synclient prpperties are also right.
I am using
- ubuntu 12.04
- intel i5 sony vaio laptop
- My system is up to date.
