Title:
In Lubuntu, Synaptics touchpad double-tap to open works badly
Status in xserver-xorg-input-synaptics package in Ubuntu:
Confirmed
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/erratically/badly. It often requires a VERY fast double-
tap, or a very fast double-tap with extra force, but even these
measures may not work.
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.
In accord with http://wiki.ubuntu.com/Debugging/TouchpadDetection (the
section "Touchpad features work, but does not work correctly and as
expected"), I will include xmodmap, xinput, evtest and xev attachments
in a logs.tar.gz archive. For evtest and xev, I tried to capture a
single double-tap between typed letter "a" identifiers.
