Plymouth/zh

Plymouth 是一个在启动过程早期运行的应用程序，提供图形启动动画，被大多数面向桌面的 Linux 发行版所使用。

用法

例如，您可以通过以下代码使用 adi1090x's collection 中的启动动画：

❄︎ configuration.nix

{ pkgs, ... }: {
  boot = {

    plymouth = {
      enable = true;
      theme = "rings";
      themePackages = with pkgs; [
        # By default we would install all themes
        (adi1090x-plymouth-themes.override {
          selected_themes = [ "rings" ];
        })
      ];
    };

    # Enable "Silent boot"
    consoleLogLevel = 3;
    initrd.verbose = false;
    kernelParams = [
      "quiet"
      "udev.log_level=3"
      "systemd.show_status=auto"
    ];
    # Hide the OS choice for bootloaders.
    # It's still possible to open the bootloader list by pressing any key
    # It will just not appear on screen unless a key is pressed
    loader.timeout = 0;

  };
}

During the graphical boot process, it is possible to switch to text mode and back by pressing the escape key.

If you are using LUKS encryption and the password prompt falls back to text mode, it may help to switch to initrd-systemd mode:

boot.initrd.systemd.enable = true;

While the default bgrt theme supports graphical password entry, this may not be supported by all themes.
