So, I suppose I don't have compatibility with Nouveau. lsmod lists modules that are currently loaded into the kernel. It has nothing whatsoever to do with compatibility. Compatibility is about nvidia drivers and nouveau drivers, or rather lack of compatibility. You must not have both modules loaded, they are mutually exclusive (if they are to work properly). However, you have to make sure yourself that when you use one the other does not load. That's why you have to either blacklist nouveau or rebuild initramfs if you want to use nvidia. That's also why you have to completely uninstall nvidia if you want to use nouveau. > My question here is what's the purpose of keeping compatibility with > Nouveau. To switch back and forth from Nvidia to Nouveau? There is no compatibility between them.

Note that he said *recreate*. That means moving the file elsewhere and creating a new file (with the same name but different contents) in its place. The fact that you have those files in /boot doesn't say anything about their contents. > > To use the default initrd, but disable the nouveau driver, edit > > /etc/grub.conf and add the following to the end of the line(s) starting > > with > > > > 'kernel': > > rdblacklist=nouveau > > I don't have this in grub.conf That is an alternative to recreating the initramfs above, more convenient for some users. You can either recreate initramfs, or use the rdblacklist option in the kernel, with the same goal of preventing nouveau from loading at startup. And you have to do that if you want to use the nvidia blob instead of nouveau. And the other way around, if you want to use nouveau, you must uninstall and remove all traces of the nvidia blob (and recreate initramfs yet again, and/or remove the rdblacklist option from grub.conf, in order to re-allow nouveau to load at boot). > So, from what I gather, my configuration shouldn't prevent the Nvidia > driver from working in any way, correct? You didn't actually provide any information above that can be used to determine the state of your system. Since you don't have the rdblacklist option in grub.conf, I can only guess that *if* your initramfs is original from the installation, nouveau should get loaded and you should *not* try to use the nvidia driver. However, *if* you did recreate the initramfs to blacklist nouveau (after installing the nvida blob from rpmfusion), than you should be ok to run the nvidia driver. Does this make things clearer? Marko P.S. Marcel, note the total absence of smileys and the lack of "HTH" in my signature above. It might have something to do with car differentials and sarcasm.
