Public bug reported:
Hi,
There is an issue with this clickpad's simulated clicks. Specifically,
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
a very short window after the first tap, 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.
This problem exists upstream as well, tested as of this writing on the
latest mainline kernel (version 3.18rc7).
Things I have tried:
Believing it to be a possible configuration issue, I attempted to increase the
double-tap window by running the command:
synclient MaxDoubleTapTime=500
to allow a half-second delay instead of the default 180ms. However even after
disabling and re-enabling the touchpad (xinput disable/enable <id>), there was
no change in the brevity of this window.
WORKAROUND: Tapping three times will register as a double-tap with a
much more forgiving windolw of opportunity, but this is not ideal as it
sometimes will also count the third click as its own separate click,
which could cause unforseen problems in places where only a double-click
specifically is desired.
