Description Peter Hutterer 2014-10-30 04:18:38 UTC 
Kinetic scrolling is useful on e.g. touchpads, where a flick with two fingers triggers a scroll motion that continues depending on the speed of the motion.

libinput currently sends 0/0 scroll events at the termination of a finger scroll, but this is not neither detectable ahead of time.

Potential solution would be something along the lines of libinput_event_pointer_axis_get_source() that responds with some identifier that tells us how the event was generated.
