Flake assumes iwd is enabled on NixOS

[johnDeSilencio]

Hello! Thank you for creating this awesome Rust project. I saw your post on Reddit and wanted to take it for a spin.

Problem

I run NixOS on my laptop, so I went ahead and installed iwmenu using the instructions in the README.

I use rofi for my app launcher. When I run iwmenu --menu rofi, this is the error that I get:

Error: org.freedesktop.DBus.Error.ServiceUnknown: The name net.connman.iwd was not provided by any .service files

IWD

After some googling, it looks like iwd is a daemon for managing wireless connections in Linux.

Minimally, I feel like this dependency should be documented in the README. Better yet, is there some way that users of the flake would get an error if iwd isn't enabled on their system?

Looks like I was able to get rofi to work after enabling iwd in my networking settings:

# configuration.nix
{ ... }:
{
  networking = {
    wireless.iwd.enable = true;
    networkmanager.enable = true;
  };
}

But whenever I try to connect to a WiFi network, I now get the following error:

LOG: Connecting to new network: <redacted>
LOG: org.freedesktop.DBus.Error.NotFound: No matching method found
Error: org.freedesktop.DBus.Error.NotFound: No matching method found

Any insights would be appreciated!

The dependency on iwd is clearly specified in the Prerequisites section of the README. Unless a NixOS module is created for iwmenu, there's no way to ensure that the iwd option is enabled and properly configured with different network managers via the flake, making this solution a bit overkill.

Your error appears to be related to a configuration issue. Try connecting through the CLI to confirm.

iwctl device list
iwctl station DEVICE scan
iwctl station DEVICE get-networks
iwctl --passphrase=PASSPHRASE station DEVICE connect SSID

Make sure there are no conflicts in your network configuration. I personally don't use NetworkManager, but it seems necessary to set iwd as the backend via networking.networkmanager.wifi.backend = "iwd";
