<h3>Lid reopen hybernate issue</h3>
=== Lid reopen hybernate issue ===


Upon closing the lid to the laptop and reopening, an issue occurs where the device will intermittently go back into hybernate mode after around 10-30 seconds. Setting the kernel parameter <code>button.lid_init_state=open</code> fixes this issue. The following is an example configuration (working in NixOS 22.05):

<h3>Getting the Nvidia card to work properly with external displays</h3>
=== Getting the Nvidia card to work properly with external displays ===


In order to get both the laptop display and external displays working, in the BIOS settings set Chipset > GPU MODE to "Dedicated GPU only".
In order to get both the laptop display and external displays working, in the BIOS settings set Chipset > GPU MODE to "Dedicated GPU only".


After setting the GPU MODE to "Dedicated GPU only" in the BIOS, enabling [[Nvidia#sync_mode sync mode| Nvidia]] is necessary in order for both the laptop's display and external display/ports to work properly. Here is an example configuration snippet for NixOS 22.05:

== Updating your system to use the unstable drivers and daemon ==
If you are using a new model from Razer, it probably is not available in the stable packages.
But it might be available in the unstable ones.
Add the below to your system configuration:
<syntaxHighlight lang=nix>
  nixpkgs.config = {
    allowUnfree = true;
    packageOverrides = pkgs: {
      stable = import <nixos-stable> { config = config.nixpkgs.config; };
      unstable = import (fetchTarball "https://github.com/NixOS/nixpkgs/archive/nixos-unstable.tar.gz") { config = config.nixpkgs.config; };
    };
  };
  # updates the whole kernel to unstable so you have the correct drivers.
  boot.kernelPackages = pkgs.unstable.linuxPackages;
  # overrides the openrazer-daemon that the harware.openrazer.enable starts
  nixpkgs.overlays = [
    (final: prev: {
      openrazer-daemon = pkgs.unstable.openrazer-daemon;
    })
  ];
  environment.systemPackages = with pkgs; [
    unstable.polychromatic
  # alternatively
  # unstable.razergenie
  ];
</syntaxHighlight>
== USB disable Issues ==
If you are encountering issues that your Razer keyboard does light up on boot shortly and then can not be found by the open-razer-daemon until you unplug your USB cable and re-plug it. Then you might want to reset your USB on startup so that after login the daemon finds it again.
<syntaxHighlight lang=nix>
# Razer usb reset. Since it disables somehow on boot.
systemd.services."usb-reset" = {
  enable = true;
  description = "Resets usb port for my Razer Keyboard";
  after = ["multi-user.target"];
  serviceConfig = {
      User = "root";
      Type = "simple";
      ExecStart=pkgs.writeShellScript "unit-restart-usb7_3" ''
        echo '7-3' |tee /sys/bus/usb/drivers/usb/unbind
        echo '7-3' |tee /sys/bus/usb/drivers/usb/bind
      '';
      KillMode = "process";
      Restart = "on-failure";
  };
  wantedBy = [ "graphical.target" ];
};
</syntaxHighlight>
The text <code>7-3</code> is composed of the bus number (7) and the port (device?) number (3).
To find the bus and port numbers, read this post: [https://superuser.com/questions/1707773/how-to-turn-usb-connected-device-on-and-off-in-linux]
If that does not work, you can reset all USB controllers instead <ref>https://unix.stackexchange.com/questions/704341/how-to-reset-usb-controllers</ref>:
