Suspend issue on Lenovo Legion 11AHP15

Help
1

I have a major suspend issue on my Lenovo Legion 11AHP15 RTX 5070 on Linux. Usually, I would be able to close the lid of my laptop, suspend and and open the lid straight to Niri. When I do actually close the lid of my laptop and wake it from suspend, I would be met with a black screen and a blinking cursor. When I switched VT, it would totally hang the entire system.

I have tried tweaking my Nvidia configs but no boot parameters work. It feels like I have hit a brick wall. This issue has followed me from Arch Linux all the way to NixOS. I thought it could be a BIOS issue so I updated it. It’s still the same. I am on nvidia-open.

This is my gpu-nvidia.nix:

{ config, lib, pkgs, ... }:

{
  hardware.nvidia = {
    modesetting.enable = true;
    open = true;

    package = config.boot.kernelPackages.nvidiaPackages.beta;

    nvidiaSettings = true;

    powerManagement.enable = true;
    powerManagement.finegrained = true;

    powerManagement.kernelSuspendNotifier = true;

    prime = {
      offload = {
        enable = true;
        enableOffloadCmd = true;
      };
      amdgpuBusId = "PCI:196:0:0";
      nvidiaBusId = "PCI:1:0:0";
    };
  };

  boot.kernelParams = [
    "nvidia.NVreg_EnableS0ixPowerManagement=1"
    "nvidia_drm.fbdev=1"
    "nvidia.NVreg_TemporaryFilePath=/var/tmp"
  ];

  # Prevent systemd 256+ from freezing user sessions and deadlocking the Nvidia driver
  systemd.services.systemd-suspend.environment.SYSTEMD_SLEEP_FREEZE_USER_SESSIONS = "false";

  services.xserver.videoDrivers = [ "nvidia" ];

  boot.blacklistedKernelModules = [ "nouveau" ];

  hardware.graphics = {
    enable = true;
    enable32Bit = true;
  };
}
