--- Comment #7 from Moritz Bunkus <moritz at bunkus.org> ---
Thanks for looking in this one, too.

Running "sudo libinput-debug-events" does not show any tap event, only
POINTER_MOVEMENT events when moving a single finger, and POINTER_BUTTON events
when I press or release the whole touchpad.

Running "sudo libinput-debug-events --enable-tap" does not change anything. No
tap events are shown, only POINTER_MOVEMENT events when moving a single finger, 
and POINTER_BUTTON events when I press or release the whole touchpad.

Having "sudo libinput-debug-events --enable-tap" running and executing "sudo
evemu-play tapclicking.evemu" in another terminal only shows POINTER_MOVEMENT
events and a couple of POINTER_BUTTON events in the later stages, but no tap
events at all. I remember pressing the touchpad (really clicking, not tapping)
during that recording.

Another tidbit of information for which I meant to file a separate bug report
(maybe it'll be of help; if not just ignore it, I'm not trying to conflate
issues here): the touchpad only recognizes right-clicks in a tiny area to the
right of the middle. The whole touchpad is ~10cm wide, and I'd say the area
recognized as a right-click is between 6.0cm and 7.0cm. I often need three
tries or more to hit the area.

Anything else I can try or provide?
