Up!
I'd like to be able to launch some non-steam games from Steam, but use the native SDL from the app launched
It is especially useful for games from emulators.
You're really open-source friendly, pretty sure it's doable

Still suffering from this issue... Got a fancy Steam Controller with gyro and all sorts of bells, yet cannot use motion controls in emulators like Cemu... Disappointing :/

all you can do is be really REALLY patient dude 😔

this is such an annoying issue and i can't believe it's not fixed yet

are there any present workarounds? i'm trying to play celeste natively, but the steam overlay is not working and as far as i know i can't force sdl on the controller like i could on proton.

For those affected by this i've found a workaround while we wait for steam to give us a proper way to disable steaminput for steam controllers/steamdeck controls.

Steam uses the SDL_GAMECONTROLLER_IGNORE_DEVICES environment variable to tell SDL to ignore certain controllers so that they don't receive double input from steaminput and the actual controller. You can use SDL_GAMECONTROLLER_IGNORE_DEVICES="" %command% in a games launch options to prevent sdl from ignoring any devices, or you could probably use the SDL_GAMECONTROLLER_IGNORE_DEVICES_EXCEPT env var (i haven't tested this one myself) to just disable it for your steam controllers VID/PID.

This doesn't work for me, at least not on any games I play. Dolphin and Cemu still can't use gyro input. I'm on Windows though so idk

Do dolphin and cemu work with your steam controller when you don't launch them through steam? If not then they probably aren't built using a recent enough version of SDL3 which supports the steam controller without steaminput. It was only just added a little after the controller came out.

Also, idk if you can set env vars on windows like that, you might have to make a powershell script or something where you use the $Env:SDL_GAMECONTROLLER_IGNORE_DEVICES="" syntax. I'm on linux so the launch options thing I mentioned is using the syntax of a posix like shell to set the env var for a process

dolphin works with my steam controller when i don't launch it through steam but cemu doesn't, and i thought you meant launch options like the field in steam properties

Even in Windows, SDL3 should need to have a toggle inside steamworks to opt out of steam controller and use games native steam controller support.

Windows is currently such an input hell and many small devs don't even care... I don't want it like this. Steam controller Lizard mode should have firmware level switch to emulate xinput, dinput and beeps to know which mode it is until claimed by HID request to switch out of Lizard Mode. Please consider.

SDL3 can then provide support, and steam should have a way to let third party game use the controller. And an user facing option to completely ignore and not hijack the Steam Controller like it does for all other controller types.

Currently, the Linux driver surpasses Windows situation. The hardware Lizard mode needs improvement, either through firmware or on a driver level. Possible, I'm pretty sure it's possible...
