Xorg and the nVidia Driver
Following the Gentoo Linux nVidia Guide
to a T, my first shot produced an nvidia driver that would lock the system when X was started. Not lock the system like; make the mouse freeze, lock the system like make it impossible to log into. I took a look at my current kernel configuration and saw that support for PCI-e had not been built in by the installation time genkernel invocation. How can genkernel claim to do anything automatically when it can't figure out that I need PCI-express support? I compiled this in, but included framebuffer support at the same time and produced a different problem.
With framebuffer support compiled in for nVidia cards, the card could not be probed during startup. This caused the kernel nvidia module to fail when loading was attempted. A few searches on the excellent and information plentiful Gentoo forums talked about framebuffer support being a bad thing when using the nvidia kernel module. Once it was removed, the kernel module loaded properly and everything works great. GLX gears reports 1300 fps and I'm ready to move onto the soudcard support.
