Sorry for the inconvenience, but I did post those on 3/31, 3:27 am Japan 
time.

(slightly abbreviated) copy of that post:
I tried running "synclient TouchpadOff=0" in a terminal.
That gives me the error message:
"Couldn't find synaptics properties. No synaptics driver loaded?"
Using Package Manager I looked for "synclient". There was ONE package 
installed
and I added the only other apparently related package 
(xserver-xorg-input-synaptics dbg 1.8.2-ubuntu1)

That did not change anything.

Somebody else previously suggested using the commands:
"xinput set-prop 14 "Device Enabled" 0 (to disable and 1 to enable)"
THAT command actually works.
Device ID: here "14".
A few days ago I tried to "update" my system, made a mistake somewhere 
and ended up with an "upgrade" to 15.10.

BEFORE the upgrade the same device had the ID "12". AFTER the upgrade 
the same device suddenly has the ID "14".
