fw13-auto-brightness 🚧 (v0.1-beta)

fw13-auto-brightness is a system for automatic laptop screen brightness control based on ambient light sensor data.

The project consists of two parts:

• AutoBrightnessIluminance — a C++/DBus daemon running in the background and managing screen brightness.
• AutoBrightnessUI — a Qt-based application for configuring the daemon parameters through a graphical interface.

└── README.md

Development environment

The project was originally developed on Arch Linux (KDE Plasma).

The daemon uses systemd/*.h for DBus/systemd integration.

The UI is built on top of Qt6.

For a full list of required libraries, check demon/CMakeLists.txt and ui/CMakeLists.txt

Build

Requirements:
- CMake ≥ 3.10
- Qt6 (Core, Widgets, DBus, Charts, Svg, Concurrent)
- systemd headers/INIReader

#UI
cd ui
mkdir build && cd build
cmake ..
make
./AutoBrightnessUI

#SERVICE
cd demon
mkdir build && cd build
cmake ..
make
./AutoBrightnessIluminance

Installation

Requires administrator privileges!

cd installer
sudo ./i.sh /opt

The script will:

• Copy files to /opt/autobrightnessiluminance
• Install autobrightness.desktop and autobrightness.service
• Automatically start the daemon via systemd

Note: the daemon starts immediately after autobrightness.service is installed!service!

Contributing

PRs and bug reports are welcome ;)

Planned:

• Add more settings to the UI
• Extend support for other DEs (Gnome, XFCE)
• Test across different laptops
