Bug Description

After I upgraded to ubuntu 17.04, touchegg (a program that translates multitouch touchpad gestures to actions) will not recognize three and four finger multitouch gestures from my elantech touchpad. I think this is related to the upgrade of xserver-xorg-input-synaptics to version 1.9.0-1ubuntu1.

Touchpad Elantech ID ETD0108

What I expected:
touchegg multitouch three and four fingers scroll/swipe to work as before the upgrade
What happened:
Three and four fingers are not recognized. Nothing happens (no errors).

I have the same problem. Here is a github bug report about it : https://github.com/JoseExposito/touchegg/issues/300

Max, excellent and thank you for cross-referencing with Jose Exposito.

I have moved from the synaptics driver to libinput (remove xserver-xorg-input-synaptics and install xserver-xorg-input-libinput), and I replaced touchegg with libinput-gestures (https://github.com/bulletmark/libinput-gestures). Does it work? Yes. Does it work better than touchegg? No. There are fewer options for both libinput and libinput-gestures. But anyway, I have my three- and four- figer up swipe at least.

Same problem after apt update && apt upgrade. Ubuntu 16.04.2 Unity, synclient -V outputs 1.8.3.
Running touchegg in the foreground doesn't show any signs of life with any gesture.

Guys, I recently updated my Ubuntu 16.04 (did not upgrade to 17.04), and I lost touchegg functionality. I looked around and found this:

https://gist.github.com/urbie-mk2/ae80fedbeded12084b7227b0ef53aeec

I got functionality back by running the comments by bndr32. Basically I am downgrading my synaptics driver. Hope that helps!
