run xinput watch-props "device name" while syndaemon does its work.
what values does the "Synaptics Off" property take? unless the -t flag is
given to syndaemon, it should be the equivalent of TouchpadOff=1

And for 1.8 that should disable everything but physical clicks, so I'm
unsure what happens here.
