NixOS Configuration

Modular NixOS config with Flakes and Home Manager for three hosts:

• laptop — Intel Arc GPU, primary machine
• desktop — NVIDIA RTX 3070, i7-8700K
• rpi4 — Raspberry Pi 4, home server (pihole + vaultwarden)

Stack

• WM: Hyprland 0.55 (from github:hyprwm/Hyprland/v0.55.0)
• Shell: DankMaterialShell (quickshell-based, Material You theming via matugen)
• Greeter: greetd + tuigreet
• Terminal: WezTerm (CovenantUI colors)
• Shell: Zsh + Powerlevel10k
• Editor: Neovim (lazy.nvim)
• Fonts: JetBrainsMono Nerd Font

Installing on a new machine

Quick install (use the bootstrap script)

Boot the NixOS minimal ISO, then:

# Set Norwegian keyboard (skip if not needed)
loadkeys no

# Run the bootstrap script
bash <(curl -s https://git.nomedal.com/nome/nixos/raw/branch/master/scripts/bootstrap.sh)

Or clone manually and run it:

mkdir -p ~/.config/nix
echo 'experimental-features = nix-command flakes' > ~/.config/nix/nix.conf
nix-env -iA nixos.git
git clone https://git.nomedal.com/nome/nixos ~/nixos
bash ~/nixos/bootstrap.sh

The script will:

1. Check network connectivity
2. Show lsblk and ask which disk to wipe
3. Run disko (partitions, LUKS, btrfs subvolumes, mounts)
4. Copy the repo to /mnt/etc/nixos
5. Run nixos-install
6. Set root and user passwords via nixos-enter

After reboot, go into BIOS and set the NVMe as first boot device.

Manual install steps

See CLAUDE.md for the full annotated manual sequence.

Day-to-day usage

# Apply config changes — omitting #hostname uses the machine's hostname automatically
sudo nixos-rebuild switch --flake /etc/nixos

# Update all flake inputs
nix flake update
sudo nixos-rebuild switch --flake /etc/nixos#desktop

# Update a single input
nix flake lock --update-input hyprland

# Check config evaluates before applying
nixos-rebuild build --flake /etc/nixos#desktop

# Garbage collect
sudo nix-collect-garbage --delete-older-than 30d

Notes

• DMS handles all theming (matugen, wallpaper → Material You colors). Don't add waybar, mako, fuzzel, etc.
• quickshell comes from the flake overlay, not nixpkgs — the nixpkgs build doesn't support the AppId pragma DMS uses.
• Spotify is managed by spicetify-nix — do not use Flatpak or nixpkgs spotify. Updates via normal nix flake update.
• /etc/nixos is owned by user for direct git access without sudo.
