Topic Description

Detailed Description

I followed the Container Installation guide to create an Isaac Sim Docker container on an Ubuntu 24.04 + L40S server and launched the app in ./runheadless.sh mode. From a Windows 11 PC, I used the WebRTC Streaming Client app to connect to the Isaac Sim app running in the container.

However, copy and paste do not work at all between the client and the server. Specifically, I can’t paste content copied on the Windows client into the Streaming Client app (Ubuntu/server), and likewise I can’t paste content copied in the Streaming Client app back into the Windows client.

Moreover, any key input in the Streaming Client app triggers the following warning.

2025-11-07T03:14:42Z [2,759,606ms] [Warning] [carb.windowing-glfw.plugin] GLFW initialization failed.
2025-11-07T03:14:42Z [2,759,606ms] [Warning] [carb] Failed to startup plugin carb.windowing-glfw.plugin (interfaces: [carb::windowing::IGLContext v1.0],[carb::windowing::IWindowing v1.5]) (impl: carb.windowing-glfw.plugin)

Thank you

The warning messages you’re seeing shouldn’t affect copy-and-paste functionality directly. In my experience, copy-and-paste works correctly when both the client and the container host are running Ubuntu. If possible, please try using the WebRTC client from an Ubuntu system to see if the issue persists. This can help determine if the problem is specific to the Windows client.

Following the container installation guide, we tested copy-paste on the Windows Streaming Client app connected to an Ubuntu machine running an Isaac Sim 5.1.0 container. We can confirm that copy-paste works as expected in this setup. FYI.
