Bazzite, the Fedora-based version of Linux that's designed for the next generation of Linux gaming has a fresh release out with some great improvements, especially for gaming handhelds like the Steam Deck OLED, Lenovo Legion Go, ASUS ROG Ally and others.
Installed this on my Legion Go today. Took about an hour, all hardware supported out-of-the-box. Hardest part was mapping the controller. Haven’t actually played much on it, but I’m very impressed with the experience so far.
