I'm working on a cluster server, and there are no monitors attached to nodes of the cluster. Each node of the cluster equipped with two Nvidia video cards, and I want to start a xserver for each node to create a OpenGL context for 3D off-screen rendering. but the "xinit" was failed because monitors are needed.
Is there a solution to setup a virtual monitor or something for each video card so the OpenGL context could be created?
many thanks for your help:)
