i3wm: how to configure touchpad?

The easiest way to do it is with synclient.


synclient -l

to list all options and their current settings and then you can use:

synclient var1=value1 [var2=value2] ...

to change the different options.

To make changes permanent you can either create a script and run it on i3 logon or edit the file /etc/X11/xorg.conf.d (if you don't have it copy it from /etc/X11/xorg.conf.d/50-synaptics.conf ). In /etc/X11/xorg.conf.d you should write your settings under:

Section "InputClass"
Identifier "touchpad"
Driver "synaptics"
MatchIsTouchpad "on"

In the form:

Option "var1" "value1"

For tap-click and vertical scroll on right you should add:

Option "TapButton1" "1"
Option "VertEdgeScroll" "0"

You can also take a look at arch linux wiki page about Touchpad_Synaptics

If you want more gestures take a look at touchegg

Since Touchpad Synaptics is no longer actively updated you can use libinput instead.


Section "InputClass"
    Identifier "touchpad"
    Driver "libinput"
    MatchIsTouchpad "on"
    Option "Tapping" "on"
    Option "ScrollMethod" "edge"

Here are all options listed.
