Declarative NixOS 26.11 flake for a modern Wayland desktop — **labwc** compositor + **Noctalia V5** AI desktop shell + **Voxtype** voice-to-text.

Designed for AMD hardware (GPU + CPU microcode) with pure Wayland (no XWayland). Drop your `hardware-configuration.nix`

alongside the flake and rebuild.

**Labwc**— lightweight Wayland compositor, 4 virtual desktops, multi-monitor (DP-2 + eDP-1)** Noctalia V5**— AI-powered shell (panel, launcher, session, OSD recommender)** Voxtype**— offline voice-to-text via Whisper.cpp (ggml-base multilingual, ~142 MB), triggered by Right Alt** Color sync**—`noctalia-labwc-theme-sync`

reads Noctalia's palette → WCAG-contrast window decorations →`labwc --reconfigure`

**greetd + tuigreet**— auto-login TUI greeter with NixOS Blue theme** PipeWire**— audio with ALSA + PulseAudio compat, WirePlumber session manager** Screen capture**— Print screen →`grim`

+`slurp`

region select →`satty`

annotation editor**Night light**—`W-n`

toggles`wlsunset`

(2500K),`W-S-n`

kills it**OBS-cmd**— scene switching (`Alt-1..5`

,`Alt-e`

) and recording toggle (`Alt-r`

)**Bluetooth**— enabled (no power-on-boot)** ZRAM**— 50% of RAM, zstd compression** AMD fine-tuning**—`amdgpu.runpm=0`

(fixes PSP LOAD_TA), microcode updates,`spectre_v2=on`

**GNOME Keyring**+** polkit-gnome**— credential storage and privilege escalation** Nix GC**— automatic weekly, deletes generations older than 7 days** GDK/icon fixes**— Adwaita icon theme linked, Trash icon visible in Nautilus** Compose key**— Caps Lock as compose key (Wayland-native)** XKB: Caps Lock**as compose key** SSH**— OpenSSH server enabled

```
sudo nixos-rebuild switch --flake /etc/nixos#nixos --accept-flake-config
cd /etc/nixos
nix flake update             # update flake.lock to latest inputs
sudo nixos-rebuild switch --flake .#nixos --accept-flake-config
```

The current user is `g`

. To rename it, edit `configuration.nix`

:

- Change
`users.users.g`

to`users.users.<newname>`

(line ~300). - Update the
`initial_session.user`

in`services.greetd.settings`

(line ~186) from`"g"`

to`"<newname>"`

. - Rebuild with
`sudo nixos-rebuild switch`

and reboot. - The old home directory
`/home/g`

will remain — either symlink it or move contents.

`--accept-flake-config`

is required to trust the`noctalia.cachix.org`

binary cache.- Noctalia is pinned via the
`cachix`

branch (always points to the latest cached commit). - Bootloader:
**Limine**(not systemd-boot). `hardware-configuration.nix`

is**not** in the repo — generate it with`nixos-generate-config`

on your machine.
