Public bug reported:
Hi,
I asked a question here
https://answers.launchpad.net/ubuntu/+source/xinput/+question/668859 but
no one seems to answer... So I try here
I can't make multitouch work with my yoga 720 convertible. At least not
as expected. The touchscreen work, some gestures work but touchscreen is
not able to handle multiple touch event unless I disable Gesture
parameter.

I work with ubuntu 18.04 / Xorg / xinput. Prior to this version I was
working with 17.10 / wayland. On 17.10 in order to make multitouch
support more than 2 fingers at once I had to disable gnome gestures.
Unfortunately, this is not working on ubuntu 18.04.
So I found a parameter for my touchscreen called Gesture (Gesture -
Turns on/off multi-touch gesture events (default is on).)
By disabling this parameter for my touchscreen, multitouch is working as
expected. But no more ... Gestures !
I think both should work together
