I have a machine that I'm using the on board video card (non-nvidia) to drive the monitor, and I have 2 Nvidia GPU's installed and functional with the latest drivers. My CUDA GPU applications work but I'd like to tweak some settings. From my understanding, nvidia-settings can't be used unless an nvidia GPU is driving a monitor (real or virtual), is this correct?

I'm really looking for a solution for tweaking GPU settings without having to have an Nvidia GPU driving a monitor, or X at all. Thank you

I'm really looking for a solution for tweaking GPU settings without having to have an Nvidia GPU driving a monitor, or X at all. I simply don't want CUDA resources being used at all to drive a monitor. Maybe running nvidia-settings on Xvfb or something similar is an option?
