Not sure why the changes don't make it into grub.  If I blacklist nouveau in kernel params manually, the nvidia driver works fine.

    caused by transitioning from nouveau drivers to the Nvidia
    drivers.  I installed the Nvidia drivers but my system continues
    to boot the nouveau drivers.   If I blacklist the nouveau drivers,
    my system boots and runs the Nvidia drivers just fine.   The
    kernel parameters I want to add are for blacklisting the nouveau
    driver.  (See above).


    Did you install from rpmfusion, or somewhere else?  If rpmfusion, did
    you install the akmod-nvidia package?

I'm not sure what happens now, as I no longer use the nvidia package since switching to using Fedora in a VM, but with earlier versions of Fedora, when using the akmod-nvidia package from rpmfusion or the equivalent package from negativo17 (which I switched to for better Fedora compatibility) the blacklisting of the nouveau drivers used to be automatically place in the kernel options in /etc/default/grub, but these options also only worked properly after they worked around the issue of the nouveau drivers being installed into the initramfs img files.

I think there is a file added to /etc/modprobe.d with the blacklist entry. You need to install a new kernel or regenerate the initramfs using dracut for it to take effect at boot.
