I have the same problem with non-EGL building
and for EGL building , I got Segmentation fault (core dumped)

edit：
openai/gym#366
re-installing the nvidia driver with --no-opengl-libs works for me.

Try to add before executing the command
xvfb-run --server-args="-screen 0, 1280x1024x16"
Instead of
Xvfb :1 -screen srcn 1280x1024x16
export DISPLAY=:99

@Archangelsg Running that command just gives me the error xvfb-run: usage error: need a command to run.
Are you sure the command you put in your comment is the exact command you used?

[tellamon]

@owen-m1 you need to give the command you want to execute after xvfb-run as follows

xvfb-run --server-args="-screen 0, 1280x1024x16" ffmpeg -i /test/input1.mp4 /test/input2.mp4 -filter_complex gltransition -y /test/out.mp4

[clickear]

run cmd
/usr/bin/Xorg -noreset +extension GLX +extension RANDR +extension RENDER -logfile ./xdummy.log -config /etc/X11/xorg.conf :1 &
it work for me!
