Joystick and Gamepad not detected in games when using Gamescope for Elite Dangerous

[Crystal4276]

Is there an existing issue for this?

• I have searched the existing issues

Are you using any gamescope patches or a forked version of gamescope?

• The issue occurs on upstream gamescope without any modifications

Current Behavior

Gamescope Joystick/Gamepad Input Issue

Environment

• Joystick: Microsoft SideWinder Precision Pro (USB) , XBOX gamepad
• Game: Elite Dangerous (Steam version)
• Gamescope version: 3.15.15

Issue Description

The joystick and the gamepad are not detected by the game when running under Gamescope, despite working correctly without Gamescope.

Steps To Reproduce

1. Joystick/Gamepad works correctly when launching Elite Dangerous directly
2. While running under Gamescope, /dev/input/js0 shows the device is still present and readable:
   jstest /dev/input/js0 for the joystick
   Driver version is 2.1.0.
   Joystick (Microsoft Microsoft SideWinder Precision Pro (USB)) has 6 axes (X, Y, Rz, Throttle, Hat0X, Hat0Y)
   and 9 buttons (Trigger, ThumbBtn, ThumbBtn2, TopBtn, TopBtn2, PinkieBtn, BaseBtn, BaseBtn2, BaseBtn3).

Attempted Solutions

1. Using Steam Input configuration
2. Launching with Steam integration enabled (gamescope -e)

Expected Behavior

The joystick should be detected and usable in Elite Dangerous when running under Gamescope, just as it is when running the game directly.

Additional Notes

The joystick remains detected at system level (verified through jstest) even while Gamescope is running, suggesting this is specifically an input passthrough issue within Gamescope.
