I try xvfb-run -s "-ac -screen 0 1280x1024x24" glxinfo and got some error: Xlib: extension "GLX" missing on display ":99". Error: couldn't find RGB GLX visual or fbconfig

it looks like something to do with nvidia drive, https://github.com/openai/gym/issues/366

edit: after removed nvidia drive, cuda and all libGL.so installed by nvidia, everything is ok now.

@transitive-bullshit Can you please help. I am getting the error Ubuntu docker container. I am able to run everything successfully on mac but not able to run on ec2 instance with a dockerized node app.

Read the existing issues and docs on using xvfb.

I am also getting the same issue while using Node JS ffmpeg-concat module

Failed to create OpenGL context. Please see https://github.com/stackgl/headless-gl#supported-platforms-and-nodejs-versions for compatibility. ffmpeg-concat: 1977.991ms UnhandledPromiseRejectionWarning: Error: failed to create OpenGL context

It would be appreciable if anyone can help me.

@DanisHack @mdjamiruddin0647 Make sure you have the dependencies required for headless-gl apt install -y ffmpeg curl build-essential python3 python3-dev python python-dev libx11-dev libxext-dev libxext6 xvfb libxi-dev libglew2.1 libglew-dev pkg-config (I think that's all of them).

When you want to run ffmpeg-concat <videos> you have to prepend the command with xvfb, like this xvfb-run -s "-ac -screen 0 1920x1080x24" ffmpeg-concat -t crosswarp -d 1250 video1.mp4 video2.mp4

@wavecommander I am running an alpine nodejs container and tried the command prepend and it does not work either.
