Loading the output preset replaces the GUI-managed Excluded Apps list, so the exclusions are declared in the preset. Meeting apps apply their own gain control, and local media playback is better left unprocessed. Assisted-by: DeepSeek Harness 0.2.1-rc.2 (deepseek-flash)
Base Desktop Environment Configuration
This directory contains base configurations for Linux desktop environments.
Overview
The configuration is split into modules:
- Desktop shell: Noctalia Shell
- Applications: desktop tools, browsers, editors, media players
- Development tools: IDEs and development utilities
- System integration: input methods, theming, XDG specifications, GPU settings
Noctalia
Noctalia (v5) is a native C++/Wayland desktop shell that replaces multiple separate tools. It is
installed through the upstream
programs.noctalia Home Manager
module.
Configuration
Noctalia merges every *.toml in the config directory (~/.config/noctalia/), sorted
alphabetically, and then layers the state directory's settings.toml on top:
| Layer | Location | Notes |
|---|---|---|
| Config | ~/.config/noctalia/*.toml |
Merged alphabetically; [include] supported; host-specific overrides |
| State | ~/.local/state/noctalia/settings.toml |
Written by the Settings UI; loads last and wins |
The shared baseline (noctalia/config/config.toml) is deployed as an out-of-store symlink, so
manual edits hot-reload without a home-manager switch. Noctalia never rewrites files in the config
layer, so volatile runtime data (wallpaper rotation, widget geometry) stays in the state file and
out of the repository.
noctalia config export prints the merged user config and noctalia config validate checks a file.
Application theming stays with catppuccin/nix, so Noctalia's theme templates are disabled.
Component Replacement
Noctalia consolidates functionality that previously required multiple tools:
| Traditional Component | Purpose | Noctalia counterpart |
|---|---|---|
| gammastep | Blue light filter | [nightlight] |
| swaylock | Screen locker | built-in lock screen ([lockscreen]) |
| anyrun | Application launcher | launcher panel ([shell.launcher]) |
| mako | Notification daemon | [notification] |
| waybar | Status bar | [bar] + [widget.*] |
| wallpaper-switcher | Wallpaper management | [wallpaper] |
| wlogout | Session menu | [shell.session] |
| wl-clipboard | Clipboard management | built-in clipboard (encrypted history) |
| grim/slurp/satty | Screenshots + annotation | built-in [shell.screenshot] + annotation editor |
