Mujoco Issue in Headless Rendering #34

Open pulkitag opened 7 years ago

I am following the instructions over here, but I keep running into issues such as:

Xlib:  extension "GLX" missing on display ":99".

Any pointers?

Mujoco needs an X11 server with OpenGL support in order to work. The xvfb package installed normally on Ubuntu 16.04 should provide it, but various things can go wrong, such as having nVidia binary drivers that don't match your hardware.

Running glxinfo should tell you whether OpenGL is working. If not, googling its error messages should find something.
