Hi,

Multitouch in bitwig was working pretty well with ubuntu 17.10. I just did an ubuntu 18.04 fresh install and multitouch does not work any more. For instance the virtual keyboard recognize only one finger at a time and it is the same with the mixer...

It seems that multitouch gestures are handled by the system (zoom in / out on a libre office document for instance) so I am wondering if any of you have the same issue or if it work well for you.

Bitwig 2.3.4

I'm having the same issue. No more multi-touch and single touch is incredibly sensitive (unusable unfortunately).

Are you / were you using Wayland?

You can try to switch to Wayland in the login window and report back.

@pitrackster interesting, at least we have a data point here.

I can't try now as my 1-week old Lenovo X1 Yoga has totally died, and anyways I was having so much trouble with it as to be unbelievable; I'll get back to you folks as soon as my laptop is fixed.

Hi !

I solved It on my computer.

List hardware : xsetwacom --list -> my touch screen has the id 12

List hardware parameters for my touchscreen : xsetwacom --list parameters 12

The gesture parameter seems to be the cause of my issue

Gesture - Turns on/off multi-touch gesture events (default is on).

Disable it : xsetwacom --set 12 Gesture off

And I have multitouch working.

Hope it will help !
