Your system information

  • Steam client version 24/04/2026:
  • Distribution (e.g. Ubuntu): CachyOS
  • Opted into Steam client beta?: Tried on both
  • Have you checked for system updates?: Yes
  • GPU: Nvidia

Please describe your issue in as much detail as possible:

When using a desktop environment the steam input is only recognized after the game is already running. When using a gamescope session it is never recognized.

Steps for reproducing this issue:

  1. Turn on the controller and PC.
  2. Launch game
  3. Only the mapped gyroscope works, all the other inputs are not working.

Steps for NOT reproducing this issue:

  1. Turn on the PC only in a desktop environment.
  2. Launch game and wait for it to launch.
  3. All controller inputs work normally if the controller is turned on in D-Input mode.

OBS: I created a layout in Deadlock steam input with the name 8bitdo.

Can confirm that I'm receiving inconsistent Steam Input functionality in Deadlock only with the Ultimate 2. Haven't tested with other controllers yet. Personally I've had to restart the game over and over until the input works again. If my controller disconnects, there's a high chance it never works until I reboot again.

Nothing extracted yet.
