Steam Deck and Wayland

The article discusses the Steam Deck's use of Wayland, highlighting the technical advantages and challenges of the display server protocol in gaming, particularly around performance, input handling, and compatibility with existing X11 applications.

Background

The Steam Deck is a handheld gaming PC from Valve (the company behind Steam, the dominant PC game store). It runs a customized Linux-based operating system called SteamOS. For years, Linux desktop graphics relied on the X11 display server, but the industry is transitioning to Wayland, a newer, more secure protocol. This article discusses Valve's efforts to get the Steam Deck working well on Wayland — a technically tricky migration because many games and tools were built for X11. Key challenge: the Steam Deck's "Gamescope" compositor (a micro-compositor that isolates games from the rest of the system) has its own Wayland implementation. The post examines progress, remaining bugs (especially around input handling and screen tearing), and what still needs fixing before Wayland is fully ready for gaming on Linux.
