Tip
A fully-configured, beautiful, modern NixOS desktop
Note
with MangoWC, declaratively described in one flake.

Note
Hey, wait! DWM is also in the flake. With dwmblocks and all good stuff, ready for theme changes with ALT+W. Because we remember :)
Eight hardware-aware default hosts are ready out of the box:
sudo nixos-rebuild switch --flake .#omnix-vm # Proxmox / QEMU VM
sudo nixos-rebuild switch --flake .#omnix-intel-laptop # Intel iGPU laptop
sudo nixos-rebuild switch --flake .#omnix-intel-desktop # Intel iGPU desktop
sudo nixos-rebuild switch --flake .#omnix-amd-laptop # AMD GPU laptop
sudo nixos-rebuild switch --flake .#omnix-amd-desktop # AMD GPU desktop
sudo nixos-rebuild switch --flake .#omnix-nvidia-intel-laptop # Intel CPU + NVIDIA dGPU laptop (PRIME)
sudo nixos-rebuild switch --flake .#omnix-nvidia-amd-laptop # AMD CPU + NVIDIA dGPU laptop (PRIME)
sudo nixos-rebuild switch --flake .#omnix-nvidia-desktop # Discrete NVIDIA desktop (any CPU)Plus custom hosts β hosts/<your-name>/ is auto-picked up by
flake.nix via builtins.readDir, no edits needed. The installer
creates it for you.
Two scripts in install/ walk you from a freshly-booted NixOS ISO to
a running mango desktop:
# 1) On the install ISO (after partitioning + mount):
curl -L https://raw.githubusercontent.com/galleb/omnix/refs/heads/main/install/phase1-iso.sh | sudo bash
# 2) After first boot, logged in as your user:
curl -L https://raw.githubusercontent.com/galleb/omnix/refs/heads/main/install/phase2-system.sh | bashPhase 1 auto-detects GPU / form-factor / boot mode, asks a handful of
questions, writes a minimal configuration.nix, runs nixos-install
and reboots. Phase 2 clones the flake into ~/.local/share/omnix,
writes hosts/<host>/variables.nix with your answers, copies the
real hardware-configuration.nix into place, and runs
nixos-rebuild boot --flake .#<host>. See INSTALL.md
for full step-by-step.

Per-host configuration (username, timezone, LAN subnet, bootMode,
bootLoader, swapSize, git persona, optional app groups, drivers profile)
lives in hosts/<x>/variables.nix. Each default.nix reads from
there; no hardcoded values. UEFI hosts pick grub or systemd-boot
through bootLoader; BIOS hosts always use GRUB.
cd ~/.local/share/omnix
nix flake update # bump inputs
sudo nixos-rebuild switch --flake .#<host>
sudo nixos-rebuild switch --rollback # previous generation| Source of truth | What lives there |
|---|---|
Nix (read-only in /nix/store) |
git config, bash env, tmux, GTK/Qt theming, fonts, XCompose, MIME defaults |
Symlink β config/<app>/ (mutable, in the repo) |
waybar, mango, swaync, mako, rofi, walker, wal, wallpaper, alacritty, kitty, ghostty, nvim, mpd, mpv, fastfetch, yazi, crystal-dock, swayidle, swaylock, swayosd, wlogout, nwg-dock-hyprland, rmpc, senpai, waypaper, hypr |
The symlinked configs are the ones the omnix-theme-* / pywal scripts
mutate at runtime β they have to stay writable.
bin/omnix-init-wallpaper picks a random theme from themes/ on first
session start. After that, Alt+W (or the rofi launcher) re-rolls the
wallpaper and pywal regenerates the colour palette in ~/.cache/wal/,
which the wal/, waybar/, mako/, swaync/, rofi/, walker/ and
mango/ configs include.
The SDDM login background follows the same source: a systemd one-shot
unit (omnix-sddm-background.service) copies ~/.config/bg.jpg into
/var/lib/sddm/background.jpg before every display-manager start, and
a patched sddm-astronaut derivation points the theme at that absolute
path. New wallpaper -> visible on the SDDM screen at next login.
