Marble mouse does not scroll in 22.04 upgrade.
I have checked the /usr/share/X11/xorg.conf.d/40-libinput.conf (and the 10-libinput.conf in that directory). They both contain this:
Section "InputClass"
Identifier "Marble Mouse"
MatchProduct "Logitech USB Trackball"
Driver "libinput"
Option "ScrollMethod" "button"
Option "ScrollButton" "8"
EndSection
which worked fine in 20.04. and is recommended by Ubuntu for all versions after 18.04.
I created a 39-libinput.conf and added the above as suggested in https://help.ubuntu.com/community
I still can't get it to scroll.
My next step is to re-install 20.04 and stick with that until
the life-of-service runs out, and then stick to Arch.
I run an Arch machine and the mouse scrolls perfectly in that.
