<h2>Updating your system to use the unstable drivers and daemon</h2> | |||
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. | |||
In your configuration.nix file: | |||
<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; | |||
}) | |||
]; | |||

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="nixos" line="1"> | |||
