Description

Isaac Sim

[x] 5.1.0

Operating System

[x] Ubuntu 24.04

Kernel

[x] 6.14.0-37-generic

GPU Information

• Driver Version:580.95.05

Gamepad

[x] Microsoft Xbox Series S|X Controller

Topic Description

Detailed Description

When launching Isaac Sim, the application fails to recognize my Xbox Series S|X Controller. The carb.windowing-glfw.gamepad extension throws a "Joystick with unknown remapping detected" warning, and the controller input is completely ignored within the simulation environment. This happens regardless of whether the controller is connected via a wired USB connection or wireless Bluetooth.

Steps to Reproduce

1. Connect the Xbox Series S|X Controller to the Ubuntu 24.04 host machine (either via USB or Bluetooth).
2. Launch Isaac Sim 5.1.0 (or an Isaac Lab environment).
3. Observe the terminal / console output.

Error Messages

When connected via USB (Wired):

2026-07-20T00:29:51Z [539ms] [Warning] [carb.windowing-glfw.gamepad] Joystick with unknown remapping detected (will be ignored):  Microsoft Xbox Series S|X Controller [030000005e040000120b000017050000]

When connected via Bluetooth (Wireless):

5. Troubleshooting & Additional Context

I have verified that the controller is functioning perfectly at the OS level:

• jstest: Passed successfully for both wired and wireless connections. The system reads all axes and buttons correctly.

• pygame: A quick Python test script using pygame also successfully detects and receives inputs from the controller.

• Attempted Fixes: I tried the SDL gamepad mapping workaround suggested in this NVIDIA Developer Forum thread, but the issue persists.

Note: I have also mentioned this issue in the IsaacLab discussions here: Discussion #2809 (Comment).
