Bug Description
In Lubuntu Saucy, installed on a Lenovo 3000 C200 laptop with a Synaptics touchpad, double-tap to open a file or folder works sporadically/
Via synclient, I played with the FingerLow, FingerHigh and MaxDoubleTapTime settings, but did not arrive at something that worked.
I did eventually discover that a *triple-tap* reliably yields the behavior I would expect from a double-tap.
Using Lubuntu Live discs, I found the same behavior on a Trusty Daily Build, and on older versions at least back to Lubuntu 12.10.
I also booted a Lubuntu Trusty Build Live disc on an HP Elitebook 8530p with a Synaptics touchpad and also found the bad behavior there, though somewhat lessened. Perhaps due to the faster Core 2 Duo processor?
Booting an *Ubuntu* Saucy Live disc on the Lenovo, double-tap worked as expected. Double-tap also worked as expected on this machine under Windows Vista.
On another laptop with Lubuntu Saucy but an ALPS touchpad, double-tap worked as expected.

It seems that the synclient MaxDoubleTapTime setting (or setting MaxDoubleTapTime in /usr/share/ X11/xorg. conf.d\ 50-synaptics. conf) does not govern the Synaptics double-tap.
Instead, the Synaptics touchpad is responding to a GTK2 setting.in which the default double-tap time is 250 ms.
To change that per-user (and there is probably a global setting somewhere -- wish I knew where), create ~/.gtkrc-2.0 with the content like:
gtk-double- click-time= 400
though values up to 1000 are sometimes suggested.
