Ubuntu – How to test multi-gesture capabilities of a touchpad

touchpad

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 2

If 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.
