ReGreet not using GTK or cursor theme

[yazoink]

It's using the correct font and wallpaper but the GTK colors and cursor theme have not been applied.

Edit: on further inspection, it's not using the correct font

Currently Regreet is only themed by copying the configuration for GTK and applying it to Regreet. If that is not working then it means there is a good reason to create a mustache file for regreet only. If I am to do that I'd like to do it properly, so it takes me more than just a few minutes.

Waiting for NixOS/nixpkgs#367520 to close so I can use demo mode instead of rebooting to see a css.

[Mikilio]

I can't reproduce the issue. After taking a look at the code again, I realized that I specified fonts icons and cursor using nixos options.

@yazoink, can you maybe send me the stylix related options you are using?

[yazoink]

Here and here are my stylix options and this is how I set up regreet (after I found that the theme wouldn't apply without any extra CSS passed to it I tried a few different ways of trying to get it to work like passing the generated gtk.css directly to regreet, as well as what I have currently but nothing has worked).

[Mikilio]

A few infos I'd like to provide in advance:

• If you overwrite programs.regreet.extraCss with mkForce you simply overwrite the entire css that stylix defines with your own, which I believe is not what you're trying to do if you want to extend the config writing stuff into stylix.gtk.extraCss is the way to go, though I admit, that could be improved.
• regarding your Regreet and greetd config, something like the following is enough to set up greetd with Regreet while having it styled only by stylix:

 programs.regreet = {
   enable = true;
 };

• The font used for UI is sansSerif because of the styling guide and because serifs are hideous on UI, so only that really impacts how fonts look on Regreet.

To follow up, I recommend removing the clutter from your configuration and tweaking stylix.fonts.sansSerif to see if that changes your font.

If it does not change your font, I believe you will be forced to debug this using nix repl after loading your config with :lf . you can check the values of your config after evaluation with nixosConfigurations.cyberia.config.<ENTER-YOUR-KEY>.

It's not being themed even without the programs.regreet.extraCss. This is what I have currently:

 programs.regreet = {
   enable = true;
 };
 services.greetd = {
   enable = true;
   settings = {
     default_session = {
       command = "${lib.getExe pkgs.cage} -s -- ${lib.getExe config.programs.regreet.package}";
       user = "greeter";
     };
   };
 };

Thank you for your patience! I was able to find the error, it seems my regreet was being styled by GTK through importing correct environment variables, not through extraCss.

As a tip for your config, I would recommend removing everything under services.greetd as that is not needed and is actually missing parts from the default that is already quite minimal.

[Mikilio]

Even without the above change, Regreet will be themed with the global GTK settings, if use the default value for services.greetd.settings.default_session.command that is set when programs.regreet.enable = true.

It will set up the dbus environment which will firstly prevent a known issue affecting ReGreet.
Since in nixpkgs this is activated by default, I think it is sensible to assume that if deliberately turned it off a user is aware of its implications.

I could still not replicate your issue with fonts.
Could you report what happens when you change sansSerif fonts in stylix?

[yazoink]

It's using the correct cursor theme and font now but the GTK theme still isn't working. This is my current config for regreet/greetd:

programs.regreet = {
  enable = true;
};

Am I missing something?

To rule out that it is some light or dark mode issue, it would be helpful if you could try the PR. It should also get merged soon.
