--- Comment #6 from Peter Hutterer <peter.hutterer at who-t.net> ---
Basic outline of what's needed here:
1) libinput needs to add a scroll source 'button'
2) libinput needs to hook into the button events to send scroll events for
those buttons
3) the xf86-input-libinput driver needs to redirect the scroll button events
into the right axis (or create a new one here, not 100% sure how to best handle
this without more research)
4) the wayland protocol needs to add a new scroll source
5) all compositors need to be updated to add the new scroll source

As said above, the libinput bits 1 and 2 are the easiest. 3 needs more
research. 4 and 5 is mostly just code churn and inertia because we need to
release libinput, then wayland with the new changes.

I'm not aware of any common modern devices that use dedicated buttons to
scroll, otherwise this churn would be worth it. As it is, it'll likely take a
year or so to get this into the mainstream distributions and I'm not sure your
laptop has that much life left :)

So I'm sorry again, but I'll be marking this as WONTFIX. Keeping it open when
it's unlikely to ever be fixed doesn't help anywone either.
