You mention your laptop is new, so it is likely that the touchpad
supports multitouch and other goodies.
yes, brand new. So the OS (Xubuntu 22.04)
Synaptics driver and libinput (probably the correct, "modern" option).
xinput returns among others (when directly on the laptop, if ssh-ing from
th3 desktop it returns the desktop stuff, which I suppose is correct)
ELAN076D:00 04F3:3244 Mouse id=10 [slave pointer (2)]
ELAN076D:00 04F3:3244 Touchpad id=11 [slave pointer (2)]
(not sure why it reports twice the same device as touchpad and mouse,
there is no physical mouse attached)
Synaptics driver and libinput (probably the correct, "modern" option).
If I do xinput --list-props for device 11 (touchpad) it returns Synaptics
and for device 10 (Mouse) it returns libinput.
What does it mean ? Which one is actually used ?
It should be possible to configure the touchpad itself to send, for
example, MB2 on a two finger tap.
(the quite older - and now junked - laptop had two buttons below the
touchpad, for MB1 and MB3, and simultaneous press of them got MB2).
The current one has just the touchpad, but the lower part of it is
"depressable". Depressing and releasing in the lower left part is MB1, in
the lower right part is MB3. The exact boundary seems not reproducible
unless one uses positions very close to the extrema. The damn thing is far
too sensitive !
I'll be reading the libinput synaptics and synclient manpages.
Any suggestion welcome
