Petexy/LineXinBar ? reverse-engineered prompt

Build me a console style Linux desktop for games, apps, and media.

I want a Wayland based desktop that feels good to use from the couch with a controller, but still works with keyboard and mouse too. It should have a launcher where I can browse my games, apps, music, videos, and pictures, open desktop apps, switch between screens, and bring up a guide with quick actions like volume, brightness, screenshots, and logout.

Please include a clean settings area for themes, accent color, wallpaper, display, and sound. It should support multiple monitors and feel like each screen can be managed on its own. Add basic desktop features like file browsing, screenshots, screen sharing, and system updates. Also make it easy to run in a nested window for testing from source, and include clear setup and build instructions for Linux. If you need to check current docs or dependencies, look them up online.
