Intel and Nvidia graphics

[ruslanmalovichko]

Hi, I have now installed it on a laptop with Intel graphics, without Nvidia.
(ThinkPad X390)

/home/ruslan/hydenix-config/configuration.nix
inputs.hydenix.inputs.nixos-hardware.nixosModules.common-cpu-intel

Run printenv | grep LIBVA_DRIVER_NAME
Result: LIBVA_DRIVER_NAME=nvidia

If I open firefox, go to about:support, Hardware Decoding does not work (screen)

My solution:
/home/ruslan/hydenix-config/modules/hm/hyprland.nix

{
  hydenix.hm.hyprland = {
    extraConfig = ''
      env = LIBVA_DRIVER_NAME,iHD # Intel
    '';
  };
}

Run printenv | grep LIBVA_DRIVER_NAME
Result: LIBVA_DRIVER_NAME=iHD

If I open firefox, go to about:support, Hardware Decoding is better (screen)

Is this solution correct?

yes this looks correct, cpu's cant really do much more than h264 well anyway
Arch wiki - Hardware_video_acceleration and NixOS Wiki - Accelerated_Video_Playback are good reading for this.
