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

4. 安装字体及输入法

i18n.inputMethod = {

    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
