Redshift with geoclue2

Help

I’m trying to get redshift to work with geoclue2 but I keep getting the following error:

Jun 27 22:30:53 themis systemd[1930]: Started Redshift colour temperature adjuster.

Here is the relevant part from my configuration.nix:

services.redshift.enable = true;
services.geoclue2.appConfig.redshift.isAllowed = true;

What am I missing?

Just chipping in to say that I have the same problem. Seems that redshift simply can’t get my location. Also, KDE’s Night Color feature consistently reports my location as “Latitude: 0 Longitude: 0”.

In my case, I’m fairly certain the cause is this issue (I’m on a desktop with no wifi). Downgrading to 2.5.6 is a potential workaround.

If anyone wanders in, here are the steps: add these lines to configuration.nix:

disabledModules = [ "services/desktops/geoclue2.nix" ];
imports = [
  # other stuff
  ./my-geoclue2.nix
];

and create a file named my-geoclue.nix with the same contents as the default module, but with this at the beginning (just after let):

  pkgs = import (builtins.fetchGit {
          url = "https://github.com/NixOS/nixpkgs/";
          ref = "refs/heads/nixpkgs-unstable";
          rev = "c92ca95afb5043bc6faa0d526460584eccff2277";
      }) {};

Thanks for the tip. Seems 2.5.7 broke a lot of stuff.

There’s this issue too (don’t let the title distract you, the discussion is where all the interesting details are). I thought it might be related to that (since I don’t run a full blown desktop with a geoclue agent).

In any case, a downgrade works around this issue too.

I just switched to a manual location provider instead:

location = {
  provider = "manual";
  latitude = xxx;
  longitude = xxx;
};

Hoping a future update will bring things in order again.
