Installation

sudo mkdir /etc/X11/xorg.conf.d
sudo cp 99-synaptics-t440s.conf /etc/X11/xorg.conf.d/

sudo mkdir /etc/X11/Xsession.d
sudo cp 98x11-syndaemon /etc/X11/Xsession.d/98x11-syndaemon

You will get

Gesture Description
One finger tap Left mouse button
Two finger tap Right mouse button
Three finger tap Middle mouse button
Two finger swipe Horizontal/Vertical scrolling
Everything else Disabled (no button areas, no edge scrolling, no tap and drag, etc.)

You will also get syndaemon with this insane configuration:

syndaemon -d -t -k -i 1 -m 100
Option Description
-d Start as a daemon, ie in the background.
-t Only disable tapping and scrolling, not mouse movements, in response to keyboard activity.
-k Ignore modifier keys when monitoring keyboard activity.
-i 1 How many seconds to wait after the last key press before enabling the touchpad.
-m 100 How many milliseconds to wait between two polling intervals.
