Linux: Prevent X11/Xorg from using a (Nvidia) GPU

Hi,

when you install an NVidia GPU to run HPC tasks you usually don’t want that X11/xorg use it. This can be done by force Xorg to use the framebuffer device and prevent the nvidia_drm driver from creating a framebuffer device.
You can check this by nvidia-smi

root@debdev ~ # nvidia-smi
