A personal NixOS flake with GNOME, Stylix theming, gaming, VFIO passthrough, and a modern CLI toolchain. Previously used Bluefin OS and really enjoyed it — this configuration carries forward its opinionated, batteries-included desktop philosophy.
Steal anything useful!
- GNOME on Wayland with Stylix auto-theming
- PipeWire audio, Bluetooth, CUPS printing
- NVIDIA proprietary drivers (open kernel modules)
- VFIO GPU passthrough (Radeon WX 5100) with Looking Glass (
kvmfr) - Optimized Win10 VM — VirtIO disk/net, hugepages, io_uring, CPU pinning (P-cores for VM, E-cores for emulator), declarative libvirt definitions
- Steam + Proton-GE, GameMode, MangoHud
- Ollama with CUDA acceleration for local LLMs
- Docker, Podman, Distrobox, libvirt/QEMU/KVM, Sunshine streaming
- Btrfs with auto-scrub and restic backups
- RDP remote desktop (XRDP + GNOME Remote Desktop)
- Zen Browser (declarative wrapFirefox)
- Firmware updates via fwupd, NuPhy keyboard support, Solaar for Logitech
- Ghostty terminal with Fish integration
- Fish shell + Starship prompt + Atuin history
- Nautilus with custom bookmarks (GNOME-specific)
- MangoHud FPS overlay for gaming
- Flatpak (declarative) — Telegram, Bitwarden, Spotify, GIMP, Inkscape, Remmina, Bottles, Alpaca, Podman Desktop, Mission Center, Bazaar, Flatseal, Warehouse, Extension Manager
- bat, eza, fastfetch, fzf, zoxide
- direnv with nix-direnv, Node.js 22, Python 3, Claude Code, Zed
- Stylix dark theme — Inter font, JetBrains Mono, Papirus icons, Capitaine cursors

njust system # Build and switch NixOS config
njust user # Build and switch home-manager config
njust update # Update all flake inputs
njust clean # GC old generations + prune Docker/Podman + Flatpak
njust changelogs # Diff between current and previous generation

njust backup-status # Check backup service status
njust backup-restore # Restore latest backup to target directory
njust distrobox-create # Create a new Distrobox container
njust distrobox-enter # Enter a Distrobox container
njust bios # Reboot into UEFI firmware setup
njust # Show all available commandsnjust is a Fish shell alias defined in home-manager/programs/fish.nix that runs just with the correct Justfile and working directory. You can also use just directly when inside the ~/nix-config directory.
Or manually:
sudo nixos-rebuild switch --flake .#$(hostname)
home-manager switch --flake .All files must be git added before Nix can see them.
