@Jinghan11 >Unfortunately, even after setting the environment variables export MAGNUM_LOG=verbose and MAGNUM_GPU_VALIDATION=ON, the issue still persists. Do you see any additional information in the log when the error occurs? >Renderer:...

Thanks for the info @ambervg Here are some more troubleshooting ideas: * Is this a local or remotely accessed computer? * Does `ldconfig -p | grep libEGL` reveal a single...

@Jinghan11 >There's no extra information provided in the terminal. All operations are run on a computer without NVIDIA GPU. By the way, is CUDA indispensable for this project? You can...

@Jinghan11 , @ambervg This issue is pretty strange. This appears to be caused because `GLFW` cannot find a display via EGL ([origin of the error](https://github.com/glfw/glfw/blob/master/src/egl_context.c#L504)). I'm thinking that the root...

@ambervg Everything looks good. Are you using pre-packaged Habitat libraries, or are you building from source? Also, are you using a fresh conda environment? Some other libraries could be interacting...

Apologize for the late reply, I was away. @ambervg , @Jinghan11 Do you get the same error when running C++ viewer and Python viewers? * `./build/viewer .../skokloster-castle.glb` * `python ./examples/viewer.py...

@lvmingzhe @ambervg @Jinghan11 Perhaps we can try circumventing EGL altogether: * Change your display protocol to X11. * Build `habitat-sim` from source with GLX. * In `src/cmake/dependencies.cmake`, change [this line](https://github.com/facebookresearch/habitat-sim/blob/main/src/cmake/dependencies.cmake#L204)...

>Are you sure about 3 places? GPT says a quaternion error could be as high as 3.6 degrees. Great question. I've been running exclusively from this code for a while...

Changed to 4 decimal places.

Great point @aclegg3 ! Beware that the `magnum` dependency used in this library requires all batteries to be included, therefore we direct users to create a separate environment from `habitat`....
