system.nix had grown to 200 lines covering boot, networking, locale,
audio, Bluetooth, fonts, nix settings, hardening, DNS and RGB. Split it
by concern into boot.nix, networking.nix, locale.nix, nix-settings.nix,
security.nix and audio.nix.
Also:
- drivers.nix -> hardware.nix, absorbing Bluetooth, the I2C udev rule,
OpenRGB and printing
- fonts -> desktop.nix
- nix-ld and pkgs.file -> apps.nix
- the Bottles tmpfiles link -> users.nix, next to services.flatpak
The reorganization is behavior-neutral: the dbus-1, system-units,
user-units and system-path trees are byte-identical to the previous
build once self-referential store paths are normalized, and
`nix store diff-closures` against the running system reports exactly
one change -- go 1.26.7.

Budgie's Wayland session had been broken; Plasma 6 replaces it with SDDM
still handling the Wayland greeter. Since the KDE apps in apps.nix were
already installed as GTK/MATE replacements, Budgie's exclude-package list
is no longer needed under native Plasma.
Also: OpenRGB service + udev rule, RTL-SDR/system tweaks, lmms, qemu,
qt5/qt6 qtwayland, nix flakes enabled.
RTL-SDR Blog V4. The V4 swapped the R820T2 tuner for an R828D behind a
built-in HF upconverter, so it needs the rtlsdrblog fork of librtlsdr --
the stock Osmocom one reports no supported devices. pkgs.rtl-sdr on this
channel already is that fork (rtl-sdr-blog 1.3.5), so hardware.rtl-sdr's
default package is correct as-is. That also blacklists the DVB-T drivers
that otherwise grab the dongle on plug-in, and ships udev rules handing it
to plugdev at 0660 -- hence plugdev in the user's groups, or every SDR app
needs root. Apps: SDR++ and rtl_433; the rtl_* CLI tools come with the
driver.
Both SDR apps are overridden to drop hardware we do not own. SDR++ and
rtl_433 default to supporting every radio ever made, which pulled in UHD
(1.4 GB of USRP firmware), BladeRF and LimeSuite. gqrx was the original
choice but reaches UHD through gr-osmosdr's gr-uhd feature; SDR++ uses no
GNU Radio at all. Per-package overrides rather than a global overlay, so
nothing else is affected.
Bootloader: systemd-boot -> Limine, themed to match the Gruvbox icon
theme. Limine installs to its own EFI directory and adds its own NVRAM
entry, so systemd-boot stays on the ESP as a firmware-menu fallback.
Display manager: lightdm -> SDDM with wayland.enable. Budgie in this
channel ships only a Wayland session (labwc) and was already running as
one; lightdm just handles that badly. SDDM's greeter runs on weston, not
kwin, so no KDE compositor comes along.
Qt defaults over Budgie's GTK/MATE apps. The Budgie module force-enables
gnome-terminal and installs nemo, eom, pluma, atril, engrampa, mate-calc
and mate-system-monitor; environment.budgie.excludePackages drops all of
them in favour of konsole, dolphin, gwenview, kate, okular, ark, kcalc and
plasma-systemmonitor. default-apps.nix rewritten to match: 113
associations, video to vlc, audio to elisa, text/code to kate, and
/etc/xdg/xdg-terminals.list pointing at konsole. Fixes a real bug there --
inode/directory was mapped to gwenview, so folders opened in the image
viewer.
Hyprland-era leftovers removed. system-telemetry and weather-fetch fed
Quickshell panels that no longer exist; brightness-ctl and hotspot-start
lost their keybinds. jq went with weather-fetch. Also dropped
gnome-screenshot, playerctl and imv. vault-toggle and strip-metadata stay
-- they never depended on Hyprland.
Comments trimmed throughout: deleted anything restating the code, kept the
ones recording a why you cannot recover by reading it (systemd.gpt_auto,
disable_ertm, ptrace_scope, the stable ethernet MAC, the mimeapps.list
parser gotcha). system.nix went 225 -> 166 lines.
README rewritten -- it still described Hyprland, Quickshell and Kitty.
Screenshot dropped.
Hyprland problems prompted a full switch to Budgie (X11, lightdm).
Removes every Hyprland/Quickshell dotfile, theming script, and
hypr-specific module (theme.nix, the whole scripts/ theming pipeline,
hyprland.conf/hyprpaper.conf, the Quickshell shell QML, kitty/mako/
rofi configs) in favor of Budgie's own panel/session/theming and a
GSettings-driven icon/cursor override.
App changes:
- Konsole/Dolphin replace kitty/Thunar as the default terminal and
file manager; dropped xterm too (services.xserver.excludePackages)
- Added Okular (PDF/document viewer), KCalc (calculator), Elisa
(audio player) -- nothing filled those roles before
- Added OBS Studio
Audio/voice:
- EasyEffects for real-time mic/output effects (creates its own
selectable "Easy Effects Source" virtual mic automatically)
- A standalone "Virtual Microphone" PipeWire device (loopback module,
services.pipewire.extraConfig), fully independent of the real mic,
for routing EasyEffects/Soundux output separately from what Discord
etc. use by default
- qpwgraph for manual patchbay routing into the above
- Soundux (soundboard) installed via Flatpak -- no longer packaged in
this nixpkgs channel
default-apps.nix: Okular wired into mimeapps.list alongside the
existing Gwenview/Ark defaults; removed the Thunar-specific
"Open Terminal Here" custom-action tmpfiles rule (dead now that
Thunar's gone -- Dolphin gets the same via its built-in konsolepart
terminal panel for free).
Display Settings: drag-to-arrange multi-monitor canvas with edge
snapping (locked when only one screen is connected), 8/10-bit depth,
color management presets (sRGB/Wide/EDID/HDR+EDID), SDR
brightness/saturation, ICC profile path, VRR toggle. display-set now
takes a single pre-built descriptor instead of a fixed positional arg
list, since Hyprland's monitor keyword grew well past that.
Wallpapers: fixed the current-wallpaper highlight never loading on
open, added real first-frame thumbnails for animated wallpapers
(wallpaper-thumbs + ffmpeg), bigger 2-column grid, filename filter.
Booru: separate downloads folder from Wallpapers so browsing doesn't
clutter the wallpaper picker, bigger grid, Safe/Moderate/Explicit
rating tiers replacing the old binary toggle, sort order (Newest/
Score/Random). Fixed pagination being completely broken (a Flow
anchor violation was silently disabling the whole layout) and
Danbooru's Random sort (order:random tag times out server-side --
switched to their random=true endpoint for that case).
Wi-Fi panel: added a "Scanning.../No networks found" state and a
manual rescan button -- previously showed nothing either way, making
"still scanning" indistinguishable from a real failure.
Bluetooth: auto-scans on open like Wi-Fi now, instead of requiring a
manual click every time.
New: System Monitor panel (CPU/RAM/GPU/VRAM/disk usage, NVIDIA or AMD
detected automatically) and Weather panel (IP-geolocated or a typed
city, current + hourly forecast, Open-Meteo, no API key) with a
compact taskbar badge.
- Add qt-theme-set: a working Qt theming pipeline via qt6ct (the
QT_QPA_PLATFORMTHEME=qt6ct env var was pointing at a platform theme
plugin that wasn't even installed, so every Qt app fell back to its
own default style). Also regenerates kdeglobals' KColorScheme groups
and sets QT_QUICK_CONTROLS_STYLE=org.kde.desktop for Kirigami-based
KDE apps, whose QML-drawn chrome ignores QPalette/qt6ct entirely.
Gwenview's dialogs/content now follow the theme; its toolbar/statusbar
chrome is a known remaining gap tied to Kirigami's platform-theme
detection outside a full Plasma session
- Add GTK2 compat (~/.gtkrc-2.0: icon theme + font follow the theme;
no dark variant exists for GTK2's Adwaita engine)
- Add modules/default-apps.nix: Gwenview/Ark as system-default image
viewer/archive manager via /etc/xdg/mimeapps.list, LibreOffice
(Qt6 build), and a working Thunar "Open Terminal Here" (it shipped
calling exo-open, which isn't installed and never resolved)
- Fix display-set.sh: mktemp defaulted to /tmp, a different filesystem
than ~/.config/hypr here, making the mv into display.conf a
non-atomic copy+unlink. Hyprland's file watcher could catch it
mid-replace and throw "source= globbing error: found no match" on
any monitor mode/orientation change. Stress-tested with 60 concurrent
write+reload cycles after the fix with zero errors
- Add Osd.qml: themed top-center popup for volume/mic/brightness/media
changes. Volume and mic react directly to Pipewire so they fire for
any change, not just our own keybinds; brightness is notified
explicitly (no live service exists for DDC/CI writes); media is
driven by two playerctl --follow watchers (status + metadata) so
track changes, pause/resume, and stop all show correctly without
double-firing
- Add Super+Shift+Z/X to toggle the Left/RightBar sidebars, via a new
Quickshell IpcHandler wired to the same expand/collapse logic as the
BottomBar arrows
- Add function-key binds for volume up/down/mute, mic mute, brightness
up/down, and media play/pause/stop/next/prev (wpctl/playerctl);
extend brightness-ctl with relative up/down steps for both the
backlight and DDC/CI paths
- Add gh and playerctl to packages
- Persist last-set wallpaper and restore it via exec-once, since
hyprpaper/mpvpaper start every session with nothing loaded
- Fix Vesktop's system tray icon rendering as a broken texture: only
resolve tray icons through the icon theme when they're actual names,
not raw pixmap-sourced image:// URLs
- Launch Hyprland via start-hyprland (its official watchdog launcher)
instead of the raw binary, removing the startup warning and adding
hang recovery
- Fix Booru panel: Lewds toggle now actually persists, tag autocomplete
no longer drops/races overlapping requests, and pagination wraps
instead of overflowing off-screen
- Remove the redundant gap between windows and sidebars/tiles
(gaps_in/gaps_out, and duplicate flyout margins stacked on top of
Hyprland's automatic exclusive-zone inset)
