# NixOS Dual-Configuration Setup
|
||||
|
||||
A NixOS system with **two fully isolated configurations**:
|
||||
|
||||
1. **Dev** - Latest stable kernel, web development tooling (Docker, Node.js, direnv)
|
||||
2. **Gaming** - Zen kernel, Steam, Lutris, performance tools
|
||||
|
||||
Both share a common base: MangoWC (Wayland compositor) + Noctalia Shell, AMD RDNA 4 GPU support, and a shared `/home` directory with mutable dotfiles.
|
||||
|
||||
## Target Hardware
|
||||
|
||||
| Component | Model | Notes |
|
||||
|-----------|-------|-------|
|
||||
| CPU | AMD Ryzen 7 5700G | Zen 3, iGPU available |
|
||||
| GPU | AMD RX 9060 XT | RDNA 4, requires Kernel 6.14+, Mesa 25.0+ |
|
||||
| Motherboard | MSI B550 Tomahawk | Excellent IOMMU groups |
|
||||
|
||||
## Directory Structure
|
||||
|
||||
```
|
||||
nixos-config/
|
||||
├── flake.nix # Main flake definition
|
||||
├── flake.lock # Auto-generated after first build
|
||||
├── hosts/
|
||||
│ └── <hostname>/
|
||||
│ └── hardware-configuration.nix # Copy from /etc/nixos/
|
||||
└── modules/
|
||||
├── common.nix # Shared configuration
|
||||
├── dev.nix # Development profile
|
||||
└── gaming.nix # Gaming profile
|
||||
```
|
||||
|
||||
## Prerequisites
|
||||
|
||||
1. NixOS installed (minimal install is fine)
|
||||
2. Flakes enabled in existing config or via: `nix-shell -p nixFlakes`
|
||||
3. Know your hostname, username, timezone, and locale
|
||||
|
||||
## Quick Setup
|
||||
|
||||
### 1. Clone and Prepare
|
||||
|
||||
```bash
|
||||
# Clone this repo to your config directory
|
||||
git clone <this-repo> ~/nixos-config
|
||||
cd ~/nixos-config
|
||||
|
||||
# Replace the placeholder hardware-configuration.nix with your actual one
|
||||
cp /etc/nixos/hardware-configuration.nix hosts/<hostname>/
|
||||
```
|
||||
|
||||
### 2. Replace Placeholders
|
||||
|
||||
Edit the following files and replace these placeholders:
|
||||
|
||||
| Placeholder | Example Value | Files |
|
||||
|-------------|---------------|-------|
|
||||
| `<hostname>` | `desktop` | `flake.nix`, `modules/common.nix` |
|
||||
| `<username>` | `john` | `modules/common.nix`, `modules/dev.nix`, `modules/gaming.nix` |
|
||||
| `<timezone>` | `America/New_York` | `modules/common.nix` |
|
||||
| `<locale>` | `en_US.UTF-8` | `modules/common.nix` |
|
||||
|
||||
Also rename `hosts/hostname/` to match your actual hostname.
|
||||
|
||||
### 3. Stage Files in Git
|
||||
|
||||
```bash
|
||||
cd ~/nixos-config
|
||||
git add .
|
||||
```
|
||||
|
||||
### 4. Verify Flake
|
||||
|
||||
```bash
|
||||
nix flake check
|
||||
nix flake show
|
||||
```
|
||||
|
||||
### 5. Build and Switch
|
||||
|
||||
```bash
|
||||
# Build and switch to dev config as main system profile
|
||||
sudo nixos-rebuild switch --flake .#dev
|
||||
|
||||
# Build gaming config as separate boot profile
|
||||
sudo nixos-rebuild boot --profile-name gaming --flake .#gaming
|
||||
```
|
||||
|
||||
### 6. Reboot and Verify
|
||||
|
||||
Boot menu should show:
|
||||
- `NixOS (dev)` - Default boot
|
||||
- `NixOS (gaming, zen)` - Gaming profile
|
||||
|
||||
## Updating
|
||||
|
||||
**IMPORTANT:** Always update both profiles together to avoid kernel/Mesa version drift:
|
||||
|
||||
```bash
|
||||
cd ~/nixos-config
|
||||
git add .
|
||||
sudo nixos-rebuild switch --flake .#dev
|
||||
sudo nixos-rebuild boot --profile-name gaming --flake .#gaming
|
||||
```
|
||||
|
||||
To update flake inputs:
|
||||
|
||||
```bash
|
||||
nix flake update
|
||||
git add flake.lock
|
||||
sudo nixos-rebuild switch --flake .#dev
|
||||
sudo nixos-rebuild boot --profile-name gaming --flake .#gaming
|
||||
```
|
||||
|
||||
## Configuration Summary
|
||||
|
||||
| Config | Kernel | Key Features |
|
||||
|--------|--------|--------------|
|
||||
| `dev` | Latest | Docker, Node.js, direnv, dev CLI tools |
|
||||
| `gaming` | Zen | Steam, Lutris, MangoHUD, Gamemode, CoreCtrl |
|
||||
| **Shared** | - | MangoWC, Noctalia, AMD GPU, PipeWire, Firefox |
|
||||
|
||||
## Post-Installation
|
||||
|
||||
### Change Password
|
||||
|
||||
```bash
|
||||
passwd
|
||||
```
|
||||
|
||||
### Setup MangoWC
|
||||
|
||||
```bash
|
||||
mkdir -p ~/.config/mango
|
||||
cp /etc/mango/config.conf ~/.config/mango/config.conf
|
||||
|
||||
# Create autostart script
|
||||
cat > ~/.config/mango/autostart.sh << 'EOF'
|
||||
#!/bin/bash
|
||||
qs -c noctalia-shell &
|
||||
EOF
|
||||
chmod +x ~/.config/mango/autostart.sh
|
||||
```
|
||||
|
||||
Add to `~/.config/mango/config.conf`:
|
||||
```
|
||||
exec-once="~/.config/mango/autostart.sh"
|
||||
```
|
||||
|
||||
### Auto-start MangoWC from TTY
|
||||
|
||||
Add to `~/.bash_profile` or `~/.zprofile`:
|
||||
```bash
|
||||
if [[ -z $WAYLAND_DISPLAY ]] && [[ $(tty) == /dev/tty1 ]]; then
|
||||
exec mango
|
||||
fi
|
||||
```
|
||||
|
||||
## GPU Verification
|
||||
|
||||
```bash
|
||||
# Verify firmware loaded
|
||||
dmesg | grep -i "amdgpu" | grep -i "firmware"
|
||||
|
||||
# Check GPU detected
|
||||
lspci | grep VGA
|
||||
|
||||
# Verify Vulkan
|
||||
vulkaninfo | head -30
|
||||
|
||||
# Check ray tracing support
|
||||
vulkaninfo | grep VK_KHR_ray_tracing_pipeline
|
||||
|
||||
# Verify OpenCL
|
||||
clinfo | head -20
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Flake can't find files
|
||||
```bash
|
||||
git add . # Flakes require files to be tracked by git
|
||||
```
|
||||
|
||||
### MangoWC doesn't start
|
||||
```bash
|
||||
systemctl status seatd
|
||||
groups # Ensure user is in 'seat' group
|
||||
```
|
||||
|
||||
### RDNA 4 black screen
|
||||
```bash
|
||||
dmesg | grep -i "amdgpu" | grep -i "firmware"
|
||||
uname -r # Should be 6.14+
|
||||
```
|
||||
|
||||
### Steam doesn't launch
|
||||
Ensure `hardware.graphics.enable32Bit = true;` in common.nix.
|
||||
|
||||
### Games won't launch
|
||||
```bash
|
||||
cat /proc/sys/vm/max_map_count # Should be 2147483642 on gaming profile
|
||||
```
