XWayland is provided by the base sway candy.

XWayland

Steam is an X11 application — it requires XWayland. The base sway config has xwayland disable for headless optimization. This candy installs a sway drop-in config at ~/.config/sway/config.d/xwayland.conf that enables XWayland.

Gamescope

Gamescope is a nested Wayland compositor for games. Use it in Steam launch options:

gamescope -W 1920 -H 1080 -r 60 -- %command%

Features: resolution spoofing, FSR/NIS upscaling, FPS limiting, HDR support.

Steam Guard requires interactive login. Connect via VNC desktop, launch Steam, and log in manually. Auth tokens persist in the steam-data volume for subsequent container restarts.

/charly-selkies:sway — Wayland compositor (dependency)
