Hello world :-)

Is device supported by LibINPUT or IICHID? If so why not control it with "Narual Scroll" in /usr/local/share/X11/xorg.conf.d/40-libinput.conf :

Section "InputClass"
        Identifier "libinput touchpad catchall"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event5"
        Option "NaturalScrolling" "on"
        Option "Tapping" "on"
        Option "ClickMethod" "clickfinger"
        Driver "libinput"
EndSection

I have just discovered it recenlty and it removed all layers of wrapping scroll directions all the way :-)

Best regards :-)
Tomek

wsp(4) still does not support evdev, so no touchpad libinput options can be applied to it.
