> IMHO, the issue is that you need to tell the NVIDIA driver that a screen will be connected at any time to the GPU, but you need to supply the driver with the screen data via a custom EDID file, like so in your xorg.conf file:

Is It possible to use these GPUs to accelerate ParaView visualization even if theses cards don't have a video output??? I know how to use the pvserver/paraview. But my problem is about the X11 configuration.
