启用flatpak

1. 在/etc/nixos/configuration.nix中添加如下代码，启用flatpak

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

2. 启用蓝牙

hardware.bluetooth.enable = true; # enables support for Bluetooth
hardware.bluetooth.powerOnBoot = true; # powers up the default Bluetooth controller on boot

3. 启用系统级工具

environment.systemPackages = with pkgs; [
  vim
  wget
  pkgs.git
  pkgs.nodejs_20
  pkgs.texliveSmall
  cpkgs.hexo-cli
  pkgs.pandoc
  pkgs.vscode
  pkgs.microsoft-edge
  pkgs.texliveSmall

];

4. 安装字体及输入法

i18n.inputMethod = {
    
    enable = true;    
    type = "fcitx5";
    fcitx5.addons = with pkgs; [
      fcitx5-gtk             # alternatively, kdePackages.fcitx5-qt
      fcitx5-chinese-addons  # table input method support
      fcitx5-nord            # a color theme
      fcitx5-fluent
      fcitx5-material-color
      rime-data
      fcitx5-rime
    ];

  };

  fonts = {
    packages = with pkgs; [
      noto-fonts
      noto-fonts-cjk-sans
      noto-fonts-cjk-serif
      source-code-pro
      hack-font
      jetbrains-mono
    ];
  };

5. 配置网络

# Enable networking
networking.networkmanager.enable = true;
networking.networkmanager.dns = "none";
networking.nameservers = [
  "223.5.5.5"
  "8.8.8.8"
  "114.114.114.114"
];

6. 更新系统执行sudo nixos-rebuild switch更新系统
