So when using an external display in gamemode, the external display becomes the primary and the internal gets turned off. This doesnt work for me due to the 1-2 second delay due to my cheep HDMI hub. FPS games? Forget it. But SteamOS is linux. There should be some setting or file or something I can tweak to make the deck default to mirror instead right? IIRC the deck gamemode uses wayland, right? Is there some file I can edit to make it mirror?
