I have a system with on-board (on-CPU) graphics:
(--) intel(0): Integrated Graphics Chipset: Intel(R) HD Graphics 4000
and an nVIDIA GTX 650 Ti. The on-board graphics is what feeds my display, and the GPU is used for other things (CUDA; but you can assume it's not to be used at all if you like). Now, I want to make my Xorg completely ignore my card, not probe it or anything - not trying to use nVIDIA's drivers nor the nouveau drivers. (So it would not complain about driver issues, nor load the kernel modules etc.)
Is that possible?
