# Aurora: Lightweight Linux RGB Daemon for Legion Laptops Automate your RGB settings and reduce resource usage. - **Source:** [Hacker News: Show HN](https://news.ycombinator.com) - **Published:** 2026-07-22 - **Topic:** [Software & Engineering](https://brifing.si/c/engineering) - **Original article:** - **On Brifing:** https://brifing.si/s/dd892e30-60d6-4105-93e9-07a3dd13162f ## Project's Origin A user with a Legion Pro 5 16ARX8 model noticed that RGB settings were lost when switching to NixOS. Existing solutions disrupted the user experience, leading to the idea of developing a new project. ## Issues with Existing Solutions The existing RGB control software worked by opening a window, which was inconvenient for users. Additionally, the software consumed a lot of resources and required users to constantly remember it. ## Aurora's Innovative Approach Aurora runs as a Rust daemon and automatically activates at startup. This eliminates the need for users to manually adjust RGB settings and makes system resource usage more efficient. ## Integration with GTK4/libadwaita The project offers a minimal GUI integrated with GTK4/libadwaita for GNOME users. This GUI allows users to easily configure RGB settings and then close it. ## Improvement in Resource Consumption Aurora is 8 times lighter than previous solutions. Separating the daemon from the GUI significantly reduces memory usage and improves system performance for users. ## Future and Contributions The project is still new and open to user feedback. Aurora aims to provide a more efficient and user-friendly solution for RGB control in Linux environments. ## Sources covering this story - https://github.com/HughScott2002/Aurora-Legion — --- _Summary written by Brifing from the original reporting.
