The message from the kernel is bogus and should be ignored. See: http://bugzilla.kernel.org/show_bug.cgi?id=14164 That does something different; it stops the nouveau module being loaded during initrd phase (it's a dracut parameter). As I understand things currently, there seem to be some situations where it's enough to simply stop the nouveau module doing kernel modesetting - i.e. you just need 'nouveau.modeset=0'; even if it gets loaded in this case, nvidia still works. In other cases, it seems, nvidia doesn't work unless you stop nouveau being loaded entirely. I'm still not exactly sure what's going on there. I believe to ensure nouveau never gets loaded, you need both the rdblacklist parameter and a blacklist directive in /etc/modprobe.d (as the package currently installs). -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Fedora Talk: adamwill AT fedoraproject DOT org http://www.happyassassin.net -- adamw
