The GUI trackpad settings for my Lenovo 16IAX7 running ubuntu 24.04 6.8.0-48-generic don't seem to affect the scrolling behavior. (Neither do the mouse settings). I am using the Gnome DE and Mutter WM. I've gone through the post here but this doesn't seem to be entirely relevant to my case as (for instance) I don't see a natural scroll option. How would I get the GUI to work, or get natural scrolling running some other way?
xinput --list
gives a list of input devices of which #14 is my trackpad. Soxinput --list-props 14
gives the list of properties one of which is the "Synaptics Scrolling Distance" (no Natural Scrolling appears).By setting the scrolling distance to negative instead of positive values I get natural scrolling:
xinput --set-prop "14" "Synaptics Scrolling Distance" -86 -86
