look at the livna fedora RPMs to see how this can be solved ideally (for the user):
"The Livna Nvidia and ATI driver RPMS come with a small python script, which works as an extension to system-config-xfree86. It does all the editing of the Xorg configuration file for you while installing/activating the driver. […] Also, you do not need to drop out of X to perform the installation. And if you boot a kernel without Nvidia support, a boot script will automatically detect that the Nvidia kernel module is missing and revert to Xorg configuration." http://mirrors.ircam.fr/pub/kde-redhat/apt/svn.livna.org/packages/nvidia-glx/devel/nvidia-README.Fedora http://mirrors.ircam.fr/pub/kde-redhat/apt/svn.livna.org/packages/nvidia-glx/devel/nvidia-glx-init http://rpm.livna.org/livna-switcher.html -- installing NVIDIA non-free binary package requires manual configuration https://launchpad.net/bugs/32853 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
