Touchpad horizontal scrolling doesn’t seem to work in Openbox.
I added the following to /etc/X11/Xorg.conf.d/40-libinput.conf (created the file)
Section "InputClass"
Identifier "libinput touchpad catchall"
MatchIsTouchpad "on"
MatchDevicePath "/dev/input/event*"
Driver "libinput"
Option "HorizontalScrolling" "true"
EndSection
And, it is there,
$ xinput --list-props 11
