I just installed Lubuntu Saucy on a Lenovo 3000 laptop and I'm

Options?
Hi,
AskUbuntu? Ubuntu Forums?
Try :)
I could have added that one of the posts I saw said that double-tap
worked fine in Ubuntu, but not in Lubuntu.
So it would seem that this list ought to be a good place to bring this
up.
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
http://manpages.ubuntu.com/manpages/saucy/man1/synclient.1.html
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:
PressureMotionMinZ
PressureMotionMaxZ
PressureMotionMinFactor
PressureMotionMaxFactor
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!
