I understand that input devices are under /dev/input and they are owned by the
input group. My user is not in the input group, and my mouse works under wayland.
However, I can’t run
libinput debug-events without root, which makes me wonder if this is something I’m supposed to be able to do? I did some searching and apparently being an
input group user is a thing.
I also understand that something (systemd or other) can assign the input group on GUI login. I can’t find such a configuration option.
So my question is two-fold: do I need to be in the
input group, and how do I configure the system so that whoever logs in on the physical machine is added to
input while they’re logged in?
