Check out the xinput
command. xinput list
will give you a list of input devices;
find the ID of the one which looks like a touchpad. Then do xinput list-props <device id>
,
which should tell you what properties you can change for the input device.
You should find one called something like Tapping Enabled and a number in parens after it
(in my case, it's libinput Tapping Enabled (276)
. Finally, run xinput set-prop <device id> <property id> 1
,
and tapping should work.
To make the change permanent, find a way to run that command on startup. One way would be to add
exec xinput set-prop <device id> <property id> 1
to ~/.i3/config
.
