After further playing around, it seemed that double-tap was not 
disabled, but required *VERY* fast tapping.

I found synclient, which is installed in Lubuntu Saucy and supposed to 
control Synaptics touchpad behavior, with documentation at

That documentation indicates that the related config file is at 
/etc/X11/xorg.conf, but that doesn't exist on my machine, so at the 
moment I don't know what the universal/user configuration locations are.

synclient -l reports MaxDoubleTapTime=180 initially, and it allowed me 
to set 'synclient MaxDoubleTapTime=360.'  I'm guessing that it could 
probably be set as high as 1000.

This seemed to help, but double-tap is still unreliable: sometimes it 
seems to require unreasonably forceful tapping.

synclient also reports settings for:
But it is not self-evident to me what behaviors those settings are 
supposed to govern and if any of them would set the touchpad to respond 
to a lighter touch.

I have not yet found any better documentation, and maybe that would help 
me achieve better control.  So I'm still open to further help!
