Hi Carsten,
Thanks for the prod, it helps to rule out any mistakes I'm making trying to
test the receiving endpoint.
Turns out there wasn't an implementation issue on the application end. With
both my test screens I needed to explicitly match them to libinput,
otherwise they were treated as single point (mouse?) devices with some
two-finger scrolling, e.g.,:
Section "InputClass"
Identifier "Planar"
MatchProduct "Weida"
Driver "libinput"
EndSection
Sorry to bring platform config issues into the dev list. Appreciate the
response. :)
Cheers,
Dave.
