iGibson: ERROR: Unable to initialize EGL

Hi team, thank you for maintaining this project.

My iGibson installation went fine, but I am facing an issue that seems common among many iGibson beginners.

(igib) ➜  ~ python -m igibson.examples.environments.env_nonint_example

    Creates an iGibson environment from a config file with a turtlebot in Rs (not interactive).
    It steps the environment 100 times with random actions sampled from the action space,
    using the Gym interface, resetting it 10 times.

I went through all the closed issues related to this, but nothing helped. I also went through the troubleshooting guide and things seemed fine to me. Here are the outputs of some commands I ran to check the EGL installation:

• (igib) ➜  ~ ldconfig -p | grep EGL
    libEGL_nvidia.so.0 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libEGL_nvidia.so.0
    libEGL_mesa.so.0 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libEGL_mesa.so.0
    libEGL.so.1 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libEGL.so.1
    libEGL.so (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libEGL.so

• Reinstalling after USE_GLAD set to FALSE didn’t work either.

Please let me know if I can share any more information that could be helpful in debugging this.

Thanks!
