This project is not affiliated with Valve (wide inspiration was taken from their work on the SteamDeck). This configuration is heavily based on the gamescope-session from the ChimeraOS project.
Copy this repository file structure into the appropriate places and you'll be able to start the session on any Display Manager of your choice.
The session sources environment from ~/.config/environment.d/*.conf files.
The easiest way to configure the session is to create ~/.config/environment.d/gamescope-session.conf
and set variables there:
# Override entire OpenGamepadUI command line
OGUICMD="opengamepadui --only-qam"
# Override the entire Gamescope command line
# This will not use screen and render sizes
GAMESCOPECMD="gamescope -e -f"
