How can I run RLBench without relying on a graphical interface (including virtual screen)?

[DingChunQ]

I need to run RLBench tests on a remote cluster (CentOS) without a graphical interface, but I can't install and use Xvfb on the cluster due to insufficient permissions.
Is there a way to make RLBench run completely without relying on a (virtual) screen?

As far as I am aware you cannot. There must be some OpenGL GLX context running, either an X server or virtual X server through xvfb.
You could try building the xvfb binary on the cluster, to use it without installing through yum, because you do not need sudo to run it. Otherwise, take a look at using a apptainer container on your cluster.
