The steam controller 2026 has been working great with Wayland and HDR variables set in the game launch options before May 22nd
After May 22nd it broke with a controller update and now I can’t play my steam games with those variables set. Only works now with either no variables at all (no hdr and no launch options) or through gamescope.
Another problem the May update broke was some non steam titles with steam closed that used to work now no longer work anymore (SDL3).
Fast forward to today after a few controller updates and the new 3.4.10 SDL3 package I installed, the controller still doesn’t have the functionality back from pre-May 22nd. The SDL3 documentation on GitHub shows it made it into the release but I am not seeing it in real time.
To reproduce the issue on steam with the 2026 steam controller: update your controller and in the steam launch options make sure to only have: PROTON_ENABLE_WAYLAND=1 PROTON_ENABLE_HDR=1 ENABLE_HDR_WSI=1 %command%
For cachyOS specifically it’s: PROTON_ENABLE_WAYLAND=1 DXVK_HDR=1 ENABLE_HDR_WSI=1 %command%
Launch the game and hold down the start button (three lines) to switch to gamepad mode and your controller will not work, only the trackpads will, you can hold the three lines again to switch it back to desktop action set mode but game will think you are playing with kb/m.
