The missing Linux app for Skydimo monitor backlights. Ambilight-style screen sync on Wayland & X11, music mode, effects, tray icon. No Windows app needed.
English · Español · 简体中文 · 日本語 · Русский · Français
curl -fsSL https://raw.githubusercontent.com/SrNoelll/skydimo-linux/main/install.sh | bashWorks on Arch / CachyOS / Manjaro / EndeavourOS, Debian / Ubuntu / Mint / Pop!_OS, Fedora / Nobara, openSUSE.
The installer installs the dependencies (it asks first), adds the app to your menu, the ambiluz command and a udev
rule so the strip works without extra groups. Then plug in the strip and open Ambiluz from your app menu.

Automatic black-bar detection, smoothing, saturation, gamma, depth. Captures through xdg-desktop-portal + PipeWire (KDE Plasma, GNOME, Hyprland, Sway…) or directly on X11. Remembers the chosen screen: no dialog every time. |
| 🎵 Music mode | Reacts to whatever your PC is playing (or the mic): Spectrum, Pulse, VU meter, Ripples, Beat rainbow, Bass. Rainbow, palette or fixed colors, beat detection, auto-gain. |
| 🌈 Flow effects | Rainbow, Gradient, Aurora, Wave, Breathing, Color cycle, Twinkle, Fire — with 13 palettes, speed, size and direction. |
| 🎨 Solid color | Color picker + swatches, with Static, Breathing, Heartbeat, Candle and Blink. |
| 🏇 Light chase (跑马灯) | Horse race, Marquee, Comet, Scanner, Blocks. |
| 🔌 Plug & play | Auto-detects the port and the model (asks the controller), reconnects if unplugged, survives suspend. |
| 🛠 Calibration | "Identify sides", LED-by-LED sweep and RGB tests; direction, offset, color order, white balance, FPS. Custom layouts for any LED count. |
| 🧰 Desktop integration | Tray icon, starts with your PC by default (one checkbox to turn it off), lights off when the screen locks or the PC sleeps, smooth fades, single instance, CLI. |

Skydimo USB LED strips and light bars with the CH340 USB-serial controller (1a86:7523). The model is detected
automatically:
| Series | Models (LEDs) |
|---|---|
| Monitor, 3 sides (SK01) | SK0121 (51) · SK0124 (54) · SK0127 (65) · SK0132 (77) · SK0134 (71) · SK0149 (107) |
| Monitor, 3 sides (SKA1) | SKA124 (70) · SKA127 (81) · SKA132 (95) · SKA134 (93) |
| Monitor, 4 sides (SK0L) | SK0L21 (76) · SK0L24 (80) · SK0L27 (96) · SK0L32 (114) · SK0L34 (112) |
| Light bars | SK0201 (40) · SK0202 (60) · SK0204 (50) |
| Lamps / strips | SK0F01 (58) · SK0F02 (50) · SK0402 (72) · SK0403 (96) |
Unknown model? It still works with a custom layout (Settings → Model → Custom). Please open an issue so it can be added. Other Adalight-style CH340 strips that use the same protocol should work too.
Tested on CachyOS (Arch) · KDE Plasma 6 · Wayland with an SK0127.

xdg-desktop-portal with your desktop's backend (-kde, -gnome, -hyprland, -wlr). The installer handles all of it.
The strip is not found / "No permission"
- Run
ambiluz --probe. You should see/dev/ttyUSB0 … likely Skydimo. - Re-run the installer and accept the udev rule, then unplug and replug the strip.
- Ubuntu/Debian: the
brlttypackage steals CH340 devices —sudo apt remove brltty(the installer offers it). - Only one program can use the port: close OpenRGB, HyperHDR, Prismatik… if they are running.
Screen sync shows "permission cancelled" or nothing happens
- On Wayland a system dialog asks which screen to share: pick the monitor with the LEDs. Use Choose another screen… to change it later.
- Make sure the portal backend for your desktop is installed (
xdg-desktop-portal-kde,-gnome,-hyprlandor-wlr). - KDE shows a "screen is being shared" indicator while syncing — that is expected.
Left and right are swapped / colors start in the wrong corner
Settings → Calibration → Identify sides: left must be red, top green, right blue. If not, change Direction; use Offset if the strip starts in another corner.
No tray icon on GNOME
Install the AppIndicator and KStatusNotifierItem Support extension, or keep the window open.
Ambiluz talks to the controller over the serial port at 115200 baud using an Adalight-style frame
('A' 'd' 'a' 0x00 count_hi count_lo + RGB × N) and asks the model with Moni-A. The screen is captured at a small
size through PipeWire, averaged per LED with an integral image, smoothed and sent at ~30 fps.
See CONTRIBUTING.md for the code layout.
Issues and pull requests are welcome: new models, translations, effects, distro packages. If Ambiluz is useful to you, a ⭐ helps other Linux users find it.
