Using xserver-xorg-input-libinput 0.19.0-1 on a testing/sid system tap-to-click is configured with
Option "Tapping" "on" see man libinput. On a HP Pavilion dv-7 with click-pad the right button works by pressing down the right bottom corner of the touchpad. Also tapping with two fingers is recognized as right mouse button click (three fingers as middle mouse button). Regards, jvp.
