Worked on the Gaming-Linux-FR/GLF-OS repository to enhance cloud gaming readiness and streamline the gaming environment. Focused on package management and system configuration using Nix, the developer replaced the default video player with Celluloid and added Chromium to improve compatibility and streaming performance. They removed GNOME Software and goverlay, and disabled MangoHud by default in Steam, resulting in a cleaner, more controllable gaming setup. All changes were consolidated for maintainability and deterministic deployments, supporting ongoing QA and release cycles. The work emphasized reducing package footprint and simplifying updates, with clear, traceable commits to ensure consistency across GLF-OS deployments.
