While I have the ears of the touchpad gods, there is one more tiny
issue I'd like to report. This may be simply a configuration issue,
but I would not know how to fix it.

The window for double-tapping (tapping the touchpad twice to simulate
a double-click) is remarkably brief. Let me be clear, double-tapping
on the touchpad does work, however if you do not get the second tap
within about a 200ms window after the first, it seems to fail to
register as a double-click, counting it as two unrelated single
clicks--this is an uncomfortably short window of opportunity. A
temporary workaround seems to be triple-tapping which for whatever
reason allow for a broader window (much closer to a full second) and
registers as a double-tap, but that just seems to be a happy accident
and is certainly not an expected feature. Is there any way to broaden
that window?

look at option MaxDoubleTapTime, see man synaptics. It's been on 180ms for
at least 8 years though, so unless Ubuntu changed the defaults here nothing
should've changed recently. there's always the chance of a bug in the xorg
driver but do try to figure out if that's a Ubuntu issue first please.

Cheers,

I did not have this problem on my previous laptop with Lubuntu
installed (though it had 14.04 not 14.10--it's no longer operational
after suffering an unfortunate accident so I can't do comparison
testing with it any longer).

I promise this is my last remaining issue with the touchpad. :)
