my only complaint is that Steam Deck controller doesn’t seem to work automatically with Heroic games launched through desktop mode
If you hold start for 1 second in desktop mode you can switch between Desktop and Gamepad profile (which should just emulate a regular gamepad), assuming you don’t mean that.
Really? Where is that documented?
From what I see, the only way to do it is to launch Steam and configure it there, and Steam needs to be running while I’m playing whatever game. Or at least that’s what I found online. It seems most people add Heroic to Steam, so maybe I’ll try that.
It’s not documented directly since it’s done with Steam’s built-in controller customisation. Under desktop mode in Steam Settings -> Controller -> Desktop Layout -> Edit Layout – there are two Action Sets with the start button bound to switch between them on long press. You’ll hear a sound when it happens as well and the game will detect it as an Xbox controller.
This acts system wide as long as Steam is running but it won’t give you the per-application customisation you get by adding it to Steam.
