Where do I find those features? In Ubuntu there's only an option to enable Two-Finger-Scrolling.
Holding down CTRL while pinching or zooming will allow you to perform the gesture.
Its not the real pinch to zoom gesture as expected. Its scrollUp + Ctrl zooms in ,scrollDown+Ctrl zooms out.
and because you have the
Two-Finger-Scrolling enabled it seems like it but the right gesture is to scrollup and down with your two fingers while pressing ctrl button
I know it is a bit late but for others who may drop by
Type synclient to list all touchpad features then create a file to execute them at startup.
For example on 12.10 I am using these lines in my script:
synclient TapButton2=2 synclient TapButton3=3 synclient HorizEdgeScroll=1 synclient HorizTwoFingerScroll=1 synclient CircularScrolling=1 synclient PalmDetect=1
These enable Horizontal edge, two finger horizontal scroll, middle mouse button by tapping with two fingers and right mouse button by tapping with three fingers and palm detection to avoid unwanted clicks while typing...
But for pinch zoom. It seems there is nothing available at the moment.
Some multi-touch features can be activated with the instructions here (at least on hp dv9000, not sure about other laptops) http://ubuntuforums.org/showthread.php?t=1999255
I had success using Fusuma and xdotool. Install xdotool and the Fusuma gem and then create its config file at
~/.config/fusuma/config.yml and include the following:
pinch: 2: in: command: 'xdotool key ctrl+plus' threshold: 0.15 out: command: 'xdotool key ctrl+minus' threshold: 0.15
You may have to fiddle with the threshold and interval values until it responds to your liking.
