Where do I find those features? In Ubuntu there's only an option to enable Two-Finger-Scrolling.

    Thanks user 25656 and spacemonkeyPDX..both of these worked for me. I must say the CTRL+2 finger scroll is more convenient. Thanks once again guys... – user324836 Sep 8 '14 at 13:34

Holding down CTRL while pinching or zooming will allow you to perform the gesture.

  • @Bakly is right. AFAIK Ubuntu out of the box is oblivious to the pinch gesture. And the documentation is silent about it as well... – Adam Ryczkowski Jul 13 '13 at 7:45

    Is there a way to activate this without having to hold ctrl? – red888 Dec 12 '15 at 18:54

    Is there any way to do it the way @red888 wants? – Jus12 Nov 29 '16 at 17:43
  • I will make a new question for asking how to make this without holding the ctrl – Bhikkhu Subhuti Aug 13 at 19:15

@SpaceMonkeyPDX

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

    Thats not a gesture, this is just normal behaviour. Zoom was always ctrl + scroll – Sina Mar 15 '14 at 17:22
  • Ctrl + Pinch works as well, so it is a real pinch. – Елин Й. Apr 7 '17 at 19:26
  • @ЕлинЙ. at the time of your answer sure, but at the time this was answered pinch was not supported yet – Bakly Oct 18 '18 at 18:59

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.

    Doesn't answer the question – asymptotically Mar 13 '13 at 14:54
  • @asymptotically did you try? – wakeup Mar 13 '13 at 18:50

    The OP wanted to know how to enable pinch to zoom and twisting. And yes, I have used synclient before, and it doesn't have an option to allow pinch to zoom. – asymptotically Mar 14 '13 at 0:52
  • @asymptotically then I edited my question. last paragraph – wakeup Mar 14 '13 at 13:23

    @wakeup thanks for this answer. it gives me a hell lot of more control on my touchpad and system than ever before. Instead of creating a script I added to my bashrc. Pretty cool! Thanks again! – Ubuntuser Aug 14 '14 at 7:28

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

    In those instructions there is no pinching gesture... – Adam Ryczkowski Jul 13 '13 at 7:48

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.
