The Surface Go 2 is a portable 2-in-1 detachable tablet computer by Microsoft, featuring a 10.5-inch PixelSense Display, Intel® Pentium® Gold or Pentium® M processors, and optional LTE connectivity.

== Setup ==

Support for webcam and LTE modem requires a custom kernel from the [https://github.com/linux-surface/linux-surface linux-surface] project. Adapt the <code>flake.nix</code> of your system configuration to include the [https://github.com/NixOS/nixos-hardware nixos-hardware repository] and the specific module for your device: <code>nixos-hardware.nixosModules.microsoft-surface-go</code>.<syntaxhighlight lang="nix">
{
  description = "NixOS configuration with flakes";
  inputs.nixos-hardware.url = "github:NixOS/nixos-hardware/master";

  outputs = { self, nixpkgs, nixos-hardware }: {
    # replace <your-hostname> with your actual hostname
    nixosConfigurations.<your-hostname> = nixpkgs.lib.nixosSystem {
      # ...
      modules = [
        # ...
        nixos-hardware.nixosModules.microsoft-surface-go
      ];
    };
  };
}
</syntaxhighlight>After that rebuild your system and reboot the machine.

If the LTE modem does not appear in your network manager directly, a [https://github.com/linux-surface/linux-surface/wiki/Surface-Go-2#enabling-the-lte-modem small workaround script] is required. Add this to your system configuration<syntaxhighlight lang="nix">
systemd.services.lte_modem_fix = let
  modemFixScript = pkgs.writeScriptBin "fix_lte_modem" ''
    #!${pkgs.stdenv.shell}
    echo -n 16383 > /sys/bus/usb/devices/2-3:1.0/net/wwp0s20f0u3/cdc_ncm/rx_max
    echo -n 16383 > /sys/bus/usb/devices/2-3:1.0/net/wwp0s20f0u3/cdc_ncm/tx_max
    echo -n 16384 > /sys/bus/usb/devices/2-3:1.0/net/wwp0s20f0u3/cdc_ncm/rx_max
    echo -n 16384 > /sys/bus/usb/devices/2-3:1.0/net/wwp0s20f0u3/cdc_ncm/tx_max
  '';
in {
  wantedBy = ["multi-user.target"];
  serviceConfig = {
    Type = "oneshot";
    ExecStart = "${modemFixScript}/bin/fix_lte_modem";
  };
};
systemd.services.ModemManager.wantedBy = ["multi-user.target"];
</syntaxhighlight>It will take a couple of seconds for the modem to appear.
