enabling-touchpad-tapclick
enabling-touchpad-tapclick
This is my own personal way to enable the touchpad-tapclick without having and editing /etc/X11/xorg.conf.d/30-touchpad.conf as following example;
Section "InputClass"
Identifier "touchpad"
Driver "libinput"
MatchIsTouchpad "on"
Option "Tapping" "on"
Option "TappingButtonMap" "lmr"
EndSection
See https://wiki.archlinux.org/title/libinput for more. The script is just a child play but useful. It is written for the touchpad of the Acer Aspire E 14, E5-473-36HS model.
#! /bin/bash
devid=$(xinput list --id-only 'ELAN0501:00 04F3:300A Touchpad')
propid=$(xinput list-props $devid | awk -F '[()]' '/libinput Tapping Enabled \(/ {print $2}')
propvalue=$(xinput list-props $devid | awk '/'$propid'/ {print $5}')
if [[ $propvalue == 1 ]]; then
exit 0
else
xinput set-prop $devid $propid 1
