I launched an AWS EC2 T3 Medium Ubuntu 20.04 instance and installed blender 2.83.9 When I launch the simple command line blender -b -f 1 I get this error message :

Blender 2.83.9 (hash 5be9ef417703 built 2021-01-19 16:16:34)

Aborted (core dumped)

I searched on the web and it has to do with EEVEE and OpenGL needing a display. I was wondering if there was any solution to this problem. I found a few but it uses GPU rendering on AWS P Instances. I would like to render on General Purpose Instances.

Thanks.
