I’ve tried as https://forums.developer.nvidia.com/t/error-occured-during-the-installation-of-isaac-sim/199041/7 and https://docs.omniverse.nvidia.com/prod_launcher/prod_kit/linux-troubleshooting.html#q9-how-to-specify-what-gpus-to-run-omniverse-apps-on suggest, however it seems like the app still only use the first gpu.

Hi. Please try the latest Isaac Sim 2022.2.1 and install the latest drivers.
Also make sure to plug in the monitor to the desired GPU to run Isaac Sim.
