升级系统

官方文档：https://nixos.org/manual/nixos/stable/#sec-upgrading

比如升级到24.11，首先升级到

# sudo nix-channel --add https://channels.nixos.org/nixos-24.11 nixos
sudo nix-channel --add https://mirrors.tuna.tsinghua.edu.cn/nix-channels/nixos-24.11 nixos
sudo nixos-rebuild switch --upgrade

configuration.nix

{ config, pkgs, ... }:

{
	imports = [
		# Include the results of the hardware scan.
		./hardware-configuration.nix
	];

	boot.loader.efi.efiSysMountPoint = "/boot/efi";
	nix.settings.substituters = [ "https://mirrors.tuna.tsinghua.edu.cn/nix-channels/store" ];

	# Define a user account. Don't forget to set a password with ‘passwd’.
	users.users.searchstar = {
		isNormalUser = true;
		extraGroups = [
			"wheel" # Enable ‘sudo’ for the user.
			"networkmanager"
		]; 
	};

	# Use the systemd-boot EFI boot loader.
	boot.loader.efi.canTouchEfiVariables = true;
	boot.loader.grub = {
		enable = true;
		device = "nodev";
		efiSupport = true;
		useOSProber = true;
	};

	# Set your time zone.
	time.timeZone = "Asia/Shanghai";

	networking.networkmanager.enable = true;

	nixpkgs.config.allowUnfree = true;

	environment.systemPackages = with pkgs; [
		python3
		vim # The Nano editor is also installed by default.
		git
		openssl
		trash-cli
	]

	# Enable the X11 windowing system.
	services.xserver.enable = true;

	# Enable touchpad support (enabled default in most desktopManager).
	services.libinput.enable = true;

	# Enable CUPS to print documents.
	services.printing.enable = true;
}

修改之后要rebuild才能生效：

sudo nixos-rebuild switch

KDE

	# Enable the X11 windowing system.
	services.xserver.enable = true;

	services.displayManager.sddm.enable = true;
	services.desktopManager.plasma6.enable = true;

中文输入法

官方文档：https://nixos.wiki/wiki/Fcitx5

	i18n.inputMethod = {
		enable = true;
		type = "fcitx5";
		fcitx5.addons = with pkgs; [
			rime-data
			fcitx5-rime
		];
	};

flatpak

	xdg.portal.extraPortals = [ pkgs.xdg-desktop-portal-kde ];
	xdg.portal.enable = true;
	services.flatpak.enable = true;
