Well, Fedora installs the Intel driver as a matter of course. I suppose I could try keeping the intel modules from loading into the kernel, though I don't know exactly which ones those are. But I can look it up. Maybe that will force things to the NVIDIA driver if it doesn't crash graphics altogether. But I'm going to have to image the disk before I start doing that kind of stuff.
