Cannot cteate OpenGL-enabled SDL window SDL error:'couldn't find matching GLX visual.

[zengsh-cqupt]

Hi,
When I run the basic_agent.py remotely by Xshell and Xmanager. The lab server has 2 2080ti GPUs. It will have the error .
my system info: ubuntutu18.04, python3.6.2, CARLA0.9.6.
The error is :"Cannot cteate OpenGL-enabled SDL window SDL error:'couldn't find matching GLX visual."

could you please tell me fix where ?
Thanks.

Hi @zengsh-cqupt ,

It sounds like the GPU driver you have on your lab server doesn't have OpenGL support or lacks GLX support.

What's the output of glxinfo ?
Are you able to run glxgears? This is a small sample program to test if you have OpenGL and GLX support

but, the server GPU can work for CARLA0.9.6 locally.

Are you able to run glxgears remotely?

If remote rendering is the problem, you can install virtualGL libraries and set "render": False, in the MACAD-Gym environment config to run the environment in headless mode. You may find this gist useful for setting up virtualGL.

(MACAD-Gym supports multi-GPU setups and it will choose the GPU that is less loaded to launch the simulation.)

I can run glxgears and glxinfo remotely‘ . This si the result:

Hi @zengsh-cqupt ,
Were you able to install VirtualGL and run with "render": false ?

@praveen-palanisamy

Hi @zengsh-cqupt ,
Were you able to install VirtualGL and run with "render": false ?

Sorry，I can't reply your question in time. According to you providing info, I had successfully installed VirtualGL. But when I running, it has a issue--about(I can't remember correctly)--it needs the OpenGL version is above 4.3，but my OpenGL version is 3.3 and I can't reinstall the remote clould Display Driver.
So I can't update my OpenGl version.

[praveen-palanisamy]

Okay.
Unfortunately, I don't know of a solution to get it to work with OpenGL 3.3.
I'll update this thread if I find a workable solution.
