For best results, launch with Gamescope, so apps can launch inside of Steam. You may want to tweak the command line options depending of your setup.

You can use drm
or wayland
for the backend option. Then you can configure SDDM to autostart Steam:
[Autologin] User=yuki Session=steam-big-picture
Works better if the above doesn't work. Also, lets you easily access the desktop without having to quit Steam. Start a desktop session (such as KDE), create an icon with this desktop file, add it to ~/.local/share/applications/
, and link it in ~/.config/autostart/
:

You can use sdl
or wayland
for the backend option. Don't forget SDDM's autologin:
[Autologin] User=yuki Session=plasma
