Hi, I get the error

mujoco_py.cymj.GlfwError: Failed to create GLFW window
GLFW error (code %d): %s 65543 b'GLX: Failed to create context: BadValue (integer parameter out of range for operation)'

I am on Ubuntu 18.04. Followed all the steps as in the README.md. Interestingly it works in my laptop but when I do the exact same steps in lab system, i get the error. One thing I noticed is that my laptop has no Nvidia card whereas my lab system has. I have already added the following in my bashrc

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/ashith/.mujoco/mujoco200/bin 
export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libGLEW.so

Any help would be really appreciated

@MianchuWang @ashBabu I have the same issue, have you found a workaround for it?

Hi, fortunately I solved the problem at last. The problem was raising when I was using a headless Linux server. The problem is that glfw is unavailable without a screen. However, we can use a virtual screen xvfb, like xvfb-run python foo.py. You can read http://elementalselenium.com/tips/38-headless for more details.

I don't know whether my situation is similar to yours, but I hope you can solve it soon. : )

Hi Mianchu, Thanks a lot and your solution helps me. I wanna ask could we set up a GUI for a headless Linux server? I set up the environments in a docker container.

Hi. There are some ways to set up a GUI for a headless Linux server, e.g., TigerVNC. But I’m not very clear about the setup procedure. Sorry.

I met the same issue and I rebooted the computer system, then the code worked without the problem. I have no idea what happend...
