Yes, the libinput packages were pulled in by the dist-upgrade.  Nothing
in /usr/share/doc/xserver-xorg-input-libinput/ gives any clue on how to
use it.  There is no man page I can find.  There is
/usr/share/X11/xorg.conf.d/40-libinput.conf but again no clue on usage.

I think the workaround of using the mouse on pavucontrol or
gkrellm-volume will have to do for sound control.  Thanks!
