Issue with rendering when running the installation example

[ViktorM]

Running the default example the installation got this error on RTX 4090 laptop and Ubuntu 24.04. Any recommendations of how to fix it?

Hi @ViktorM , this seems a problem of mujoco rendering. In this issue on the mujoco repo https://github.com/google-deepmind/mujoco/issues/692 they suggest this stackoverflow solution. Can you check if that works for you too?

Thank you! I just found this thread on stack: https://stackoverflow.com/questions/71010343/cannot-load-swrast-and-iris-drivers-in-fedora-35/72200748#72200748 and this advice from there helped me:

I added the export LD_PRELOAD to my .bashrc file and it's working fine.

export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6
