Hi,
first of all, please, let me know, if I am on a wrong mailing list.
This page https://developer.ubuntu.com/en/start/ubuntu-for-devices/porting-new-device/
lead me here.

To the problem - I noticed this error message

DirectionalDragArea: recognition properties are wrongly set. Gesture
recognition is impossible

in unity8 log. I did some debugging a found that in
unity8/plugins/Ubuntu/Gestures/DirectionalDragArea.cpp there is a
method  DirectionalDragArea::itemChange which calls
value.window->screen()->physicalDotsPerInch(). The last one returns a
bad value. This leads to an inf value pixelsPerMm later and disables
the gesture recognition. For now I solved this with a little hack - I
hardcoded pixelsPerMm to 306 / 25.4. With this the gesture recognition
works. I suppose I would eventually find the correct place for this
value, but some of you may have it faster :-)

Thank you for any hints.

Pavel
