Marchyo supports Intel, AMD, and NVIDIA GPUs, including hybrid graphics configurations with NVIDIA PRIME.

​
GPU vendors

Specify which GPU vendors are present in your system: 
marchyo.graphics.vendors = [ "intel" ];
For hybrid graphics laptops with two GPUs: 
marchyo.graphics.vendors = [ "intel" "nvidia" ];
Find your GPU with: lspci | grep -E 'VGA|3D'
VendorDescription
"intel"Intel integrated graphics (iGPU)
"amd"AMD GPUs (integrated or discrete)
"nvidia"NVIDIA discrete GPUs
When vendors is empty (default), Intel packages are applied on x86_64 for backward compatibility.

​
NVIDIA options

OptionTypeDefaultDescription
marchyo.graphics.nvidia.openbooltrueUse open-source kernel modules (recommended for RTX 20xx+, required for RTX 50xx)
marchyo.graphics.nvidia.powerManagementboolfalseExperimental power management (may improve laptop battery life)
marchyo.graphics.nvidia = {
  open = true;
  powerManagement = false;
};
Set nvidia.open = false for older GPUs (Maxwell, Pascal, Volta). The open-source modules only support Turing (RTX 20xx) and newer.

​
NVIDIA PRIME (hybrid graphics)

For laptops with both an integrated GPU and a discrete NVIDIA GPU: 
marchyo.graphics = {
  vendors = [ "intel" "nvidia" ];

  prime = {
    enable = true;
    intelBusId = "PCI:0:2:0";
    nvidiaBusId = "PCI:1:0:0";
    mode = "offload";
  };
};

​
Finding bus IDs

Run lspci | grep -E 'VGA|3D' and convert hex bus IDs to the PCI:bus:device:function format (convert hex values to decimal).

​
PRIME options

OptionTypeDefaultDescription
marchyo.graphics.prime.enableboolfalseEnable NVIDIA PRIME
marchyo.graphics.prime.intelBusIdstring""PCI bus ID of Intel iGPU
marchyo.graphics.prime.amdgpuBusIdstring""PCI bus ID of AMD iGPU
marchyo.graphics.prime.nvidiaBusIdstring""PCI bus ID of NVIDIA dGPU
marchyo.graphics.prime.modestring"offload"PRIME render mode

​
PRIME modes

ModeDescription
"offload"On-demand rendering (default). Power efficient — use nvidia-offload <command> to run apps on the discrete GPU.
"sync"Always use discrete GPU. Best performance but more power consumption.
"reverse-sync"iGPU for display, dGPU for compute.

​
Examples

​
Intel-only desktop

marchyo.graphics.vendors = [ "intel" ];

​
AMD-only desktop

marchyo.graphics.vendors = [ "amd" ];

​
NVIDIA desktop

marchyo.graphics = {
  vendors = [ "nvidia" ];
  nvidia.open = true;
};

​
Intel + NVIDIA laptop (offload)

marchyo.graphics = {
  vendors = [ "intel" "nvidia" ];
  nvidia.open = true;
  prime = {
    enable = true;
    intelBusId = "PCI:0:2:0";
    nvidiaBusId = "PCI:1:0:0";
    mode = "offload";
  };
};

​
AMD + NVIDIA laptop (sync)

marchyo.graphics = {
  vendors = [ "amd" "nvidia" ];
  nvidia.open = true;
  prime = {
    enable = true;
    amdgpuBusId = "PCI:6:0:0";
    nvidiaBusId = "PCI:1:0:0";
    mode = "sync";
  };
};
