Slimbook HERO

This configuration is for the Slimbook Hero with an i7-13620H and an RTX 4060. Model name: SLIMBOOK HERO-RPL-RTX. To run software on your Nvidia GPU, use the nvidia-offload command. For example:

nvidia-offload `nix-shell -p glxinfo --run 'glxgears'`

## Power Management
My testing shows suspend issues (tested in GNOME) when using `hardware.nvidia.powerManagement.enabled = true`, regardless of the value of `hardware.nvidia.powerManagement.finegrained`. 
This seems related to this [issue](https://github.com/NixOS/nixpkgs/issues/336723), which is offered a solution in [this discouse thread](https://discourse.nixos.org/t/suspend-resume-cycling-on-system-resume/32322/12) with this config:

<details>
```nix
systemd = {
     services."gnome-suspend" = {
      description = "suspend gnome shell";
      before = [
        "systemd-suspend.service" 
        "systemd-hibernate.service"
        "nvidia-suspend.service"
        "nvidia-hibernate.service"
      ];
      wantedBy = [
        "systemd-suspend.service"
        "systemd-hibernate.service"
      ];
      serviceConfig = {
        Type = "oneshot";
        ExecStart = ''${pkgs.procps}/bin/pkill -f -STOP ${pkgs.gnome-shell}/bin/gnome-shell'';
      };
    };
    services."gnome-resume" = {
      description = "resume gnome shell";
      after = [
        "systemd-suspend.service" 
        "systemd-hibernate.service"
        "nvidia-resume.service"
      ];
      wantedBy = [
        "systemd-suspend.service"
        "systemd-hibernate.service"
      ];
      serviceConfig = {
        Type = "oneshot";
        ExecStart = ''${pkgs.procps}/bin/pkill -f -CONT ${pkgs.gnome-shell}/bin/gnome-shell'';
      };
    };
  };

At the same time, the Nvidia driver reports power management to still be working even with nvidia.powerManagement.enable = false:

>cat /proc/driver/nvidia/gpus/0000:01:00.0/power
Runtime D3 status:          Enabled (fine-grained)
Video Memory:               Off

GPU Hardware Support:
 Video Memory Self Refresh: Supported
 Video Memory Off:          Supported

S0ix Power Management:
 Platform Support:          Supported
 Status:                    Disabled
