Very sad, because all these options seem to be documented at length in
man synaptics
with a lot more gloss (and even a diagram) than is typical of man pages,
and some are even supplied as a file in the synaptics package.
Some of the options you mention are only available on clickpads and
meant nothing to me. Would I be right in thinking that this post is
the first mention of your having a clickpad?
I assume you're running stretch as I can't find a package called
xserver-xorg-input-libinput in stable. I do hope that such
"basic functionality" does not become an imposed default behaviour
in stretch just to avoid your having to apply some configuration,
sorry, workaround. For myself and many others, tap-to-click is the
bane of touchpads if you don't know how to turn it off.
Cheers,
David.
