Kenan's NixOS Configuration Suite

NixOS Configuration Suite (nixosc) - Snowfall Edition

A comprehensive NixOS configuration built on Snowfall Lib, managing both system (NixOS) and user (Home Manager) layers from a single flake.

• Architecture: Snowfall Lib (auto module discovery)
• Desktop: Hyprland + Niri + GNOME (optional) + DankMaterialShell (DMS); Waybar/Hyprpanel disabled by default
• Greeter: greetd + DMS Greeter (dms-greeter) on supported hosts
• Launchers: DMS Spotlight + Walker (Elephant) + Rofi; Ulauncher is also configured
• Theme: Catppuccin (Mocha by default) end-to-end
• Shell: Zsh + Starship + Tmux + Kitty/Wezterm
• Secrets: SOPS-Nix (Age)

Snowfall layout (all modules auto-imported via default.nix):

• flake.nix - Core configuration entry point
• install.sh - Unified installation & management tool
• systems - ❄️ Host configurations
  • hay - Laptop/Workstation
  • vhay - VM profile
• modules - 🍱 Modular configs
  • nixos - System-level (hardware, services, security, networking…)
  • home - User-level (apps, theming, shells, Hyprland, DMS, scripts)
• homes - Home-Manager profiles per host/user
• overlays - 🔧 Nixpkgs overlays
• secrets - 🔐 SOPS-encrypted material
• wallpapers - Theme assets used by DMS/Hyprland

git clone https://github.com/kenanpelit/nixosc ~/.nixosc
cd ~/.nixosc

Use the helper script to build and switch configurations:

# For Physical Machine (hay)
./install.sh install hay

# For Virtual Machine (vhay)
./install.sh install vhay

To update flake inputs:

./install.sh update

This repo can run the login screen using DMS Greeter (dms-greeter) under greetd.

Host example: systems/x86_64-linux/hay/default.nix

my.greeter.dms = {
  enable = true;
  compositor = "hyprland"; # hyprland | niri | sway
  layout = "tr";
  variant = "f";
};

Notes:

• Logs: /var/log/dms-greeter/dms-greeter.log
• The module sets a writable greeter HOME (/var/lib/dms-greeter) to avoid cache/shader warnings.

• System-wide: Edit modules/nixos/packages/default.nix.
• User-specific: Edit modules/home/packages/default.nix.

Just create a directory! Snowfall Lib automatically imports default.nix files.

• System module: modules/nixos/my-service/default.nix
• User module: modules/home/my-app/default.nix

Secrets are encrypted with Age and managed by SOPS. To edit secrets:

sops secrets/wireless-secrets.enc.yaml

• Mod is the main modifier (typically SUPER in a normal session).
• Alt + L — DMS lock (via niri-lock)
• Mod + Space — DMS Spotlight
• Reload config (no restart): niri msg action load-config-file
• Full config generator: modules/home/niri/default.nix

• $mainMod = SUPER key
• DMS ships Spotlight/panel shortcuts ($mainMod+Space, powermenu, control-center, etc.).
• Hyprland core (summary):
  • $mainMod + Enter — Kitty
  • $mainMod + Q — Close window
  • $mainMod + F — Toggle float; $mainMod+Shift+F — Fullscreen
  • $mainMod + h/j/k/l or arrows — Move focus; Shift moves window; Ctrl resizes
  • $mainMod + 1-9 — Workspace; Shift+1-9 — move window; Ctrl+1-9 — monitor-aware move
  • $mainMod + Tab — DMS Hypr overview
• Full list: modules/home/hyprland/config.nix

DMS may log lines like:

• NiriService: Failed to write layout config
• NiriService: Failed to write alttab config

This repo intentionally manages ~/.config/niri/dms/*.kdl via Home Manager (read-only symlinks), so DMS' auto-generator can't overwrite them.

This repo ships a Home-Manager module for Stasis.

Enable it in your HM profile:

my.user.stasis.enable = true;

Notes:

• Config path: ~/.config/stasis/stasis.rune
• The file is created via home.activation (not xdg.configFile) so it stays writable.
• Convenience wrapper: stasisctl ... (always uses the configured stasis.rune path)

Useful commands:

systemctl --user status stasis
stasisctl info --json
stasisctl reload
stasisctl profile work    # or: none / presentation
stasisctl dump 80
