>>> My laptop is configured with all displays hard-wired to the Intel, so my Nvidia is a headless device, but I do have headless Xorg running on it with working GL. Perhaps this same configuration would be able to output an image to external monitor on your system? This would be a separate Xorg instance, but if you do not intend to use both displays simultaneously this might be acceptable. I haven't tried connecting to both devices from one Xorg and I have no idea how GLX would be expected to function in this situation.

I am not sure where it has checked this, since it now refuses to work with an older kernel that I know it to have previously worked with. It may be looking in /usr/src, which I left checked out to the latest version.
