You can install the NVIDIA driver without modifying xorg, as that will leave you with a system that does not boot to the gui, and manually modprobe the driver… That should allow you to run CUDA programs that do not depend on the display:

disregard the MATLAB/ginfo stuff, that was for a particular CUDA add-on to matlab I was testing at the time. You might need to run the cuda programs as root, or perhaps not.
Other than this half-assed hack, I’d suggest you try with bumblebee from scratch without having installed the NVIDIA driver in the first place… if that is an optimus notebook, it’s probably the only way to make the card work fully via the optirun syntax. Post on their support website as they should have a better idea of any issues with a particular setup.
