Hello @tlbtlbtlb , I met this problem too. I use Ubuntu 14.04 LTS. And I create a fake display use xvfb-run -s "-screen 0 1400x900x24" bash, however when I use env.render() it come out with an error. (pyglet.gl.glx_info.GLXInfoException: pyglet requires an X server with GLX)
I don't know how to fix up it.

@LinZichuan
Most probably you're problems will be solved if you install your NVIDIA drivers witth the --no-opengl-files option and CUDA with the --no-opengl-libs option. pemami4911's comment on #366 finally pointed me into this direction. This solved it for me.
I used Ubuntu 16.04 but I think it'll work on 14.04 also. Just in case I wrote down what worked out for me step by step here.

@DavidSanwald Even I'm having the same issue. but reinstalling nvidia drivers is not an option for me as I don't have sudo access to the server. Is there any other solution to the problem?

@DavidSanwald same problem as @aseembits93 . Can't reinstall nvidia-drivers. Is there any other way?
