I bought new laptop and I was told that my touch pad is 'Multi Gesture Touchpad'. I'd like to zoom, scroll with two fingers and perform three finger operations.
How do I test the multi gesture capabilities of my touchpad?

You can enable two-finger scrolling by forcing the scrolling setting:
gconftool-2 --set --type=int /desktop/gnome/peripherals/touchpad/scroll_method 2If this doesn't work, try with the below script:
xinput --set-prop --type=int --format=32 "SynPS/2 Synaptics TouchPad" "Synaptics Two-Finger Pressure" 10
# Below width 1 finger touch, above width simulate 2 finger touch. - value=pad-pixels
xinput --set-prop --type=int --format=32 "SynPS/2 Synaptics TouchPad" "Synaptics Two-Finger Width" 7
# vertical scrolling, horizontal scrolling - values: 0=disable 1=enable
xinput --set-prop --type=int --format=8 "SynPS/2 Synaptics TouchPad" "Synaptics Two-Finger Scrolling" 1 1
# vertical, horizontal, corner - values: 0=disable 1=enable
xinput --set-prop --type=int --format=8 "SynPS/2 Synaptics TouchPad" "Synaptics Edge Scrolling" 0 0 0
# stabilize 2 finger actions - value=pad-pixels
xinput --set-prop --type=int --format=32 "SynPS/2 Synaptics TouchPad" "Synaptics Jumpy Cursor Threshold" 120 I have added it to my startup applications. If it doesn't seem to work, try adding a sleep 10 at the top of the script.
You can enable tapping and two finger scrolling at System -> Preferences -> Mouse -> Touchpad.
After that, you should be able to
- scroll with two fingers
- left click by tapping with one finger
- right click by tapping with two fingers
- middle click by tapping with three fingers
For zooming and other features you might have a look at utouch.
1There is no guarantee that your touchpad will be one of the supported ones in the new utouch project. But you can test it out by installing the utouch package:
sudo apt-get install utouch
I'd also recommend looking at the wiki page for all the details about utouch:
