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.

The goal is speech recognition on the NPU for vinput, and sherpa-onnx cannot
deliver it: every model it loads keeps a dynamic time axis, which the NPU
compiler rejects outright. Qwen3-ASR and SenseVoice both core-dumped in
vpux-compiler ("Got non broadcastable dimensions pair"), and reshaping the ONNX
inputs does not help because the dynamic dimensions sit inside the graph
(WA-037). Whisper is the only family OpenVINO publishes fully static IRs for,
and its fixed 30 s window is exactly what the compiler accepts.
The host now runs an OpenAI-compatible /v1/audio/transcriptions service backed
by whisper-large-v3-turbo int8 on the NPU: 1.5 s for 11 s of audio against
2.1 s on CPU, with the compiled graph cached in /var/cache so only a cold cache
pays the ~60 s NPU compile. vinput on the desktop sends raw PCM to it through a
small provider script.
Only the NPU driver and compiler still come from the unmerged branch in the
`nixpkgs-npu` input (NixOS/nixpkgs#570230), whose nixpkgs also happens to be
the one where openvino-genai 2026.4.0.0 builds at all.

No host defines a *-nixos-tests output; the pod firewall drops 5900-5903
from pod sources; the mihomo core keeps geodata and cache in its
StateDirectory; WA-020 was used twice and the cited WA-028 had no row.
Every remaining pkgs-x64 consumer runs only on x86_64-linux hosts, where the
native pkgs already carries the same allowUnfree config
(modules/nixos/base/nix.nix) and overlays (modules/base/overlays.nix), so
replace the references with pkgs and drop the extra nixpkgs instantiation
(which also removes an eval on aarch64-darwin).
media.nix keeps the native Zoom app on x86_64 hosts only, since zoom-us has
no aarch64 Linux build.
Explicit session action lists replace the built-in defaults, so re-declare all
five actions; lock stays immediate, logout/suspend/reboot/shutdown arm a 10 s
countdown that a second press runs immediately.
QT_QPA_PLATFORMTHEME=gtk3 (from #386) made Qt derive its color scheme
from GTK3, which has no dynamic dark/light signal, so Telegram and other Qt
apps were stuck on the light palette after Noctalia's theme mode changed.
Use the portal theme instead: Qt then follows
org.gnome.desktop.interface color-scheme, which Noctalia writes. The trade-off
is Qt's built-in "Sans Serif" 9pt font, which a font-providing platform theme
would be needed to change.
go-musicfox posts its own desktop notification on every track change and both popups sit at bottom_right, so the media OSD was a second, redundant popup.
Clear AltTriggerKeys, whose Shift_L default toggled on left Shift. Left Shift is now a plain modifier and right Shift switches through the shared Rime config.
Pin keyd's right-hand modifiers (rightcontrol/rightshift/rightmeta) to their own keycodes; keyd otherwise folds them into the left keys. Set Vinput's MenuKey to right Ctrl and clear CommandKeys, which would shadow it.
* fix(desktop): align Qt app fonts with GTK
Qt apps kept their built-in default font ("Sans Serif" 9) while GTK apps use
`gtk-font-name` (Noto Sans 11), so Telegram and other Qt apps rendered
noticeably smaller than GTK apps like Firefox. Set
QT_QPA_PLATFORMTHEME=gtk3; the plugin ships with qtbase, so it needs no
extra package and also gives Qt apps GTK file dialogs.
* chore(desktop): drop unused Xft.dpi from the Wayland GTK profile
Xft.dpi/ *.dpi are X11 X-resource settings. This file is only imported by
the niri (Wayland) hosts, where xwayland-satellite sets its own Xft.dpi
(96 x output scale, currently 144), and the i3 hosts are headless 1080p
computer-use sessions that do not import it. So the setting had no effect
anywhere; remove it instead of keeping a misleading knob.
Vinput's streaming Zipformer models have unbounded dynamic shapes, so
OpenVINO cannot compile them for the GPU or the NPU; the `openvino`
provider and ai's Intel NPU enablement could never run on the NPU (noted
as unverified in WORKAROUNDS WA-017). Remove the backend option, the
daemon's OpenVINO library path, and the intel-npu module enable, and
update the eval test, README and WORKAROUNDS (drop WA-016 and WA-017).
Keep Vinput's stock package and its bundled sherpa-onnx (1.13.4): the
fork-based and nixpkgs-master sherpa overrides existed only to provide the
`openvino` provider, so drop package.nix with them.

Vinput stores its core config in ~/.config/vinput/config.json and its
downloaded sherpa-onnx models in ~/.local/share/vinput/models/. Neither
was bind-mounted from /persistent on the tmpfs-root hosts, so a reboot
wiped both and vinput-daemon started with "Local ASR provider model is
not configured". Persist both directories and document the one-shot CLI
model setup in the vinput README.
* feat!: replace zellij with tuios and switch to ghostty + kitty
Terminal environment overhaul:
- add the tuios flake input (upstream 0.8.5; nixpkgs has 0.8.1) and link
the checked-in config out-of-store; auto-start tuios in nushell instead
of zellij
- remove zellij entirely: both modules, config, README and nushell
completions
- remove foot and alacritty, which lack the Kitty graphics protocol;
Manage ~/.config/go-musicfox/config.toml declaratively: the upstream default plus the mpv engine, ~/Music download dir, 2 GiB cache and cover art.
The app rewrites the file with a temp file plus rename, which would replace a plain symlink, so use force = true like fcitx5's profile: the repo copy is restored on every rebuild and runtime edits are ephemeral. Runtime data and state stay on the persistent volume.
- run two autocutsel instances so the X PRIMARY/CLIPBOARD selections stay in
sync, making copy/paste work in the session and through VNC
- drop --disable-blink-features=AutomationControlled: nothing drives the
browser over CDP, so navigator.webdriver is already false and the flag only
marked the setup as automated
- document why the driver stays on real X11/AT-SPI input and is never granted
a CDP attach, and note the SSH-tunnel path for manual VNC access
- extend the computer-use eval test
Give the idols-ruby and idols-kana VMs a headless computer-use
environment: Xvfb plus i3, driven by cua-driver (and computer-use-linux
as a fallback). Includes the system module (AT-SPI, fonts, Mesa, Clash
Verge proxy, proxy-region timezone), the home i3 module (Xvfb/i3/x11vnc
services, browser flags), host wiring and an eval test.
Update the user-facing bits that still pointed at KubeVirt: the homepage
dashboard group and entries (and drop the dead LongHorn one), the docs,
and remove the now-unneeded virtctl package.
The Settings UI stored `theme.mode` in ~/.local/state/noctalia/settings.toml, so it was not versioned. Pin it in the config baseline; the [location] sunrise/sunset schedule still drives light/dark.
At background_opacity 0.2 the light-mode surface disappears into dark wallpapers, so the dark light-mode text sits on a dark bar. Raise it to 0.61 to keep contrast while staying slightly translucent.
`programs.noctalia.settings` deploys the TOML as a store symlink, so every edit needs a `home-manager switch`. Deploy the baseline from the config layer with `mkOutOfStoreSymlink` instead: Noctalia hot-reloads config-layer files and never rewrites them, so edits apply live while Settings UI changes stay in ~/.local/state/noctalia/settings.toml (which loads last) and out of the repo.
Update the docs and host-specific comments to match the two-layer model.
Add cpu, ram, disk and network up/down sysmon widgets to the bar start lane,
matching the old v4 SystemMonitor. Set the clock to ISO date, full English
weekday and 24h time (e.g. "2026-09-19 Saturday 16:06").
- root README: VS Code config moved from home/linux/gui/base/editors.nix to vscode.nix
- READMEs now list both GUI editors (Zed, the primary one, plus VS Code)
- base README: xdg is a directory now, nvidia.nix no longer exists, editors.nix -> vscode.nix
- idols-ai README: disko-fs-media.nix -> disko-fs-data.nix (/persistent/data)
- secrets README: password-store moved from home/base/desktop to home/base/tui
- drop unused link definitions (AstroNvim, wl-clipboard, Catppuccin)
- fix a pre-existing typo flagged by the typos hook (keeped -> kept)
Noctalia v5 is the native C++/Wayland rewrite; the Quickshell-based v4 line (pkgs.noctalia-shell) is EOL and its JSON config is not migrated upstream.
- use the upstream home-manager programs.noctalia module (present at our pinned HM revision) instead of the hand-rolled package + symlink module: it installs pkgs.noctalia, validates config.toml at build time via checkConfig, and supports customPalettes; drop the v4 Qt/Qt6ct session setup
- replace the v4 settings.json/plugins.json with a minimal shared config.toml (font, Catppuccin shell palette, templates off, screenshot annotation, accessibility/bar scale, night light, wallpaper, location/weather); host-specific bits live in per-host files (shoukei's eDP-1 backlight in noctalia/host-shoukei.toml), which merge after config.toml. Application theming stays with catppuccin/nix
- treat config.toml as the single source of truth: do NOT persist ~/.local/state/noctalia and set setup_wizard_enabled = false, so UI tweaks are promoted back into the repo instead of accumulating in app-owned state
- port niri keybinds to 'noctalia msg ...', update spawn-at-startup and the backdrop layer namespace, fix the broken 'octalia-shell' media-previous bind, and replace the grim/slurp/satty screenshot stack with Noctalia's native region/fullscreen/annotate commands (drop the unused packages)
- drop the now-redundant swaybg and swaylock (Noctalia owns the wallpaper and lock screen, the latter authenticating against the PAM 'login' service) and its PAM entry; keep wlogout as an emergency fallback
- update hypridle's lock commands and the matching eval test
- refresh the noctalia docs
Install microsoft-edge on x86_64 Linux via Home Manager and on macOS via
a brew cask. Enable the chromium and brave-origin Home Manager options
alongside google-chrome, dropping the google-chrome aarch64 fallback to
chromium since google-chrome supports aarch64-linux.
Persist the Brave Origin and microsoft-edge profile directories on the
ephemeral-root hosts.
The lock listener ignores inhibitors but had no playback condition, so it locked the screen at its timeout even during active media playback (screen-off already skipped via playerctl). Add the same playerctl condition to the lock listener.
niri already owns the org.freedesktop.ScreenSaver interface and feeds its inhibitors into the compositor idle notifier, so hypridle's own registration always fails with 'Another service is already providing...'. Set ignore_dbus_inhibit = true so hypridle no longer tries to claim it; D-Bus inhibits are still handled by niri.
Replace the static hypridle.conf with services.hypridle.settings and add required timeout options so each host tunes its own values:
- idols-ai (PC): 15 min keyboard, 20 min screen-off, 30 min lock.
- 12kingdoms-shoukei (laptop): 3 / 6 / 20 min (previous values).
The options have no defaults because the right values depend on the machine. Update the home-manager eval test to inspect the settings option instead of the old config file text.
Desktop speakers on idols-ai use the EBU R128 broadcast standard (-23 dB), while the quiet built-in laptop speakers on 12kingdoms-shoukei keep -12 dB. Move the target out of the shared preset so each host sets its own value.
