Troubleshooting

For mesh loading failures, run git lfs pull. For egl-probe build failures, use the setup script’s CMake 3.x and check GCC/G++/Make. If streaming fails, check startup logs and network ports. Activate the installation environment before launching and import simulator modules after AppLauncher. Include the command, versions, GPU model and final error lines when opening an issue.

For remote access, see remote viewing setup. For force mismatches, run validation with the flat fixture and check numerical settings.

Renderer exits with code 139

If camera or viewport startup crashes in librtx.scenedb.plugin.so, check the GPU driver against Isaac Sim 5.1.0 requirements. A newer driver can run headless physics while failing RTX rendering.

NVIDIA identifies incompatible newer driver branches in Isaac Sim issue 619 and issue 650. The validated Linux driver is 580.65.06 (R580). Configure the supported driver through your host’s normal maintenance process, then retry the visual demo.

Grey visualization cells have no taxel. Active pixels at zero force use the zero-load color. The unwrapped image retains firmware (row, column) indices; it is not a camera picture. See reading data.
