--- Comment #8 from Peter Hutterer <peter.hutterer at who-t.net> ---
the palm edge detection zones are on the side, the thumb detection is at the
bottom though (see the link above).

right, so what's likely happening here then is that the finger is detected as a
horizontal scroll event, but those may be filtered out by the X driver if
horizontal scrolling is disabled there. And a finger that generates horiz.
scroll events doesn't move the pointer. do you see POINTER_AXIS events in the
output?
