Is the "nomodeset" parameter necessary in this case? Some people claim the driver didn't work without it, while others (myself included) have found it made no noticeable difference(?). It only takes 1 extra reboot to test this. > The rpmfusion.org/Howto/nVidia instructions also say that SElinux > protection should be lowered: > setsebool -P allow_execstack on > > QUESTION: Is this really necessary?

Again, test your installation without running that command (more secure). If you find SELinux errors in your log files or that the driver won't load due to SElinux then execute that command. > MOST IMPORTANT QUESTION: Suppose this doesn't work and the reboot hangs > (presumably with the X startup).

Typically when you 'yum' install the Nvidia driver like this, it is built for a specific kernel. The yum command may also install a new kernel in order to match the nvidia driver. Going back the previous kernel should work (I think). Try and see, no harm done. In the case of a locked X-server, you can as you state go back to runlevel 3. To force this at grub, hit a key to see the kernels menu and select one but don't hit enter. Hit 'E' (to edit) and scroll to the end of the 'kernel' line and add '3'. Then hit enter and 'B' to boot. Then you can do the steps you stated to remove.
