Displayflow

Displayflow is a comprehensive, high-performance display management utility for Linux, designed to give users granular control over hardware settings and monitor brightness through both a Command Line Interface (CLI) and a background Hotkey daemon. Key Features: Hardware-Level Control: Leverages DDC/CI (Display Data Channel Command Interface) to communicate directly with external monitors, allowing for hardware brightness and contrast adjustments. Unified Management: Supports both backlight control (typically for integrated laptop screens) and DDC-based control for external displays. Robust Engine: Built with a modular Rust architecture and immediate atomic commit. Smart Scanning: Automatically detects connected displays and their capabilities (Backlight vs. DDC) using an efficient scanning module. Developer-Friendly: Includes a bridge for IPC (Inter-Process Communication) and a clean CLI for easy integration into custom scripts or desktop environments. Why use Displayflow? Unlike many basic display tools, Displayflow is built for speed and reliability in Rust. It fills the gap for Linux users who need a way to control external monitors in profiles within the terminal, but also ships Desktop-Links and Hotkey wizard.
