Currently there is no logo for nixos, even though this distribution is becoming increasingly popular

Hi, I have added some new icons to theme (NixOs also). Please test and let know if it works. I will try to install NixOS later in VM to test.

Still doesn't work

Can You please paste output of command: ls /usr/share/grub/themes/catppuccin-grub-theme/icons/

    boot = {
      cleanTmpDir = true;
      plymouth.enable = true;
      kernelParams = [ "quiet" "splash" "rd.systemd.show_status=false" "rd.udev.log_level=3" "udev.log_priority=3" ];
      kernelPackages = pkgs.linuxPackages_latest;
#      kernelPackages = pkgs.linuxPackages_xanmod;
      consoleLogLevel = 0;
      initrd.verbose = false;
      loader = {
        systemd-boot.enable = false;
        efi.canTouchEfiVariables = true;
        grub = {
          enable = true;
          useOSProber = true;
          efiSupport = true;
          device = "nodev";
          theme = pkgs.fetchFromGitHub {
            owner = "catppuccin";
            repo = "grub";
            rev = "3f62cd4174465631b40269a7c5631e5ee86dec45";
            sha256 = "d15FS7R78kdUKqC7EAei5Pe0Vuj2boVnm4WZYQdPURo=";
          } + "/catppuccin-grub-theme";

        };
      };
    };

Windows logo works fine. Perhaps this is a problem with the grub

P

The problem is that icon filename should be named as a system class. And because I have no Nix installed I don't know how this name should be (right now the file is named nixos.png). But I know how to check it now - please paste here what is in file: /boot/grub/grub.cfg (You can use cat /boot/grub/grub.cfg)

OK, so I'm now stupid. According to grub2 theme guide:

If you'd like to use icons you should make directory image in the theme directory.

Then you should place icons in png format to the directory image. Icon's name should correspond to some predefined class.

Default classes:

windows > os
gnu-linux > gnu > os
osx > darwin > os
hurd > gnu > os
More important class is to the left. If icon windows.png is found then it will be shown. The icon os.png will not.

Main system's class (equal to it's name) will be available also. (main system in this case - is the system where update-grub2 script was called). This class is more important than gnu-linux.

E.g. for ROSA system this class will be "rosa" etc. You can find classes in the file /boot/grub2/grub.cfg.

With patch applied to ROSA, such class will be shown for every other installed OS on the particular computer.

I was looking for something the same as with Windows line: menuentry 'Windows Boot Manager (on /dev/sda1)' --class windows --class os

But in case of Nix i don't see anything like this.

One last chance and big request to You sioodmy (7?). Can You please try to change the name of nix file icon on nix.png in /boot/theme/icons/ directory? If this will not help I will try to find some time to install Nix and do more tests and trials.

[sioodmy]

K, I'll try it later

[sioodmy]

It didn't work 😥 https://github.com/NixOS/nixpkgs/pull/161272

[elkrien]

It didn't work disappointed_relieved NixOS/nixpkgs#161272

So it looks that it's NixOS issue. If this PR will be commited then theme is prepared for it. It looks that I'm not able to do anything more with it. Let's just wait.
