Some feedback below.

Also, the program fails to start on my end. strace indicates that it can't find the applicable socket:

socket(AF_UNIX, SOCK_STREAM|SOCK_CLOEXEC, 0) = 10
connect(10, {sa_family=AF_UNIX, sun_path="/run/user/1000/lan-mouse-socket.sock"}, 39) = -1 ENOENT (No such file or directory)
close(10)

I'm testing it here with a simple nix run .#lan-mouse and with nix build .#lan-mouse over two systems running latst nixos-unstable. Is that in a service?

EDIT: Maybe it was the lack of GIO due to not being used wrapGAppsHook (at that point).

No, I'm running directly from the terminal. No GUI opens, and the output is as follows:

And I tested this with the gtk wrapper.

Interesting, you're using the same consumers as I, but it works here, from terminal or not. (and that sock is flawlessly created)

I'm currently on swayfx and this starts fine for me.

Must be a config issue on my end, I can run this fine on my Arch system but not NixOS.

One more change to pass CI:

I'll approve if CI is happy with it

[feschber]

@PedroHLC Hi, heres the developer of lan-mouse. I'm not too familiar with nix. Do I open a pr to get the version updated?
