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" ];
marchyo.graphics.vendors = [ "intel" "nvidia" ];
Find your GPU with: lspci | grep -E 'VGA|3D'
| Vendor | Description |
|---|
"intel" | Intel integrated graphics (iGPU) |
"amd" | AMD GPUs (integrated or discrete) |
"nvidia" | NVIDIA discrete GPUs |
vendors is empty (default), Intel packages are applied on x86_64 for backward compatibility.
NVIDIA options
| Option | Type | Default | Description |
|---|
marchyo.graphics.nvidia.open | bool | true | Use open-source kernel modules (recommended for RTX 20xx+, required for RTX 50xx) |
marchyo.graphics.nvidia.powerManagement | bool | false | Experimental 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
| Option | Type | Default | Description |
|---|
marchyo.graphics.prime.enable | bool | false | Enable NVIDIA PRIME |
marchyo.graphics.prime.intelBusId | string | "" | PCI bus ID of Intel iGPU |
marchyo.graphics.prime.amdgpuBusId | string | "" | PCI bus ID of AMD iGPU |
marchyo.graphics.prime.nvidiaBusId | string | "" | PCI bus ID of NVIDIA dGPU |
marchyo.graphics.prime.mode | string | "offload" | PRIME render mode |
PRIME modes
| Mode | Description |
|---|
"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";
};
};
