How to blacklist nouveau after installing real nvidia drivers?

I’ve recently installed Rocky 9.1 on a system with an Nvidia 750ti card. I then installed the Nvidia drivers from rpmfusion, so now I ASSUME I need to blacklist nouveau. (haven’t rebooted yet, in case something blows up due to conflicting video drivers.)

back, on my old system, when I installed nvidia drivers from elrepo, then did the blacklisting for me, but AFAIK the rpmfusion ones don’t. Or at least I find no mention of it anywhere.

Guidance sought, Thanks in advance!


sorry, typo:

“then did the” ==> “they did the”

The nvidia drivers from rpmfusion should automatically blacklist it. You can verify /etc/default/grub and/or /boot/grub2/grubenv.

Thanks for the confirmation!

A little while after posting that I did look at the grub files, and saw the necessary information there, so I rebooted and voila! it seems to be working fine now.

Thanks again for the reply.


Where does this myth that rpmfusion requires any additional manual steps comes from ?

RPM Fusion project maintainer here. There is no need for any additional blacklist when using RPM Fusion nvidia packaged driver !

We use blacklist with kernel cmdline options, so that that very much the only technique that doesn’t require you to rebuild the initramfs or any other unsafe operation.

Also RPM Fusion packaged driver allows to fallback to nouveau in the case anything goes wrong with your installation. But if using Rocky kernel, there is nothing to fear…

Hope this helps.

There are many old “HowTos” out there. Newbies tend to pick the oldest one for a distro that is not even theirs.
Perhaps also from here or here

and I am a newbie only in the senses that (1) I am new to Rocky, but have used Centos for literally decades, and (2) I have always used the elrepo nvidia drivers in the past, not the ones from rpmfusion. So I simply DID NOT KNOW (and could not find documentation regarding) that rpmfusion’s Nvidia packages did the deed for me. (it makes sense that it would, but in lieu of knowledge it seemed appropriate to inquire.)


Can you post what the grub should contain that is correct? GRUB_CMDLINE_LINUX=“resume=/dev/mapper/rl_tidiabetes-swap
s/root rhgb quiet”
Mygub looks like this after Nvidia blacklist and it still complains.

on my fedora workstation with the nvidia run package , i use the following

GRUB_CMDLINE_LINUX=“rhgb quiet rd.driver.blacklist=nouveau modprobe.blacklist=nouveau nvidia-drm.modeset=1”

but thats not the only way to blacklist the nouveau driver, it can be done in /etc/modprobe.d/


cat /etc/modprobe.d/nvidia-installer-disable-nouveau.conf

blacklist nouveau
options nouveau modeset=0

just make sure you are aware how to use the various means to access your pc with the graphics driver down.

i personally dont use the rpmfusion drivers on fedora because ive had too many kernel updates from fedora that are incompatible or out of step with the rpmfusion drivers and find that ive no desktop after the update.

but thats my choice,

Both RPM Fusion and NVidia’s CUDA-repo do have NVidia’s proprietary driver as RPM.

RPM Fusion has also some legacy drivers:

The xorg-x11-drv-nvidia* package has postinstall scriplet that should add the rd.driver.blacklist=nouveau to kernel command-line:

The install from RPM Fusion is two explicit packages: xorg-x11-drv-nvidia-470xx akmod-nvidia-470xx

Their packages, like RPM Fusion and ELRepo (which does not build NVidia for el9), do update kernel commandline.

Bottomline: both RPM builds should blacklist Nouveau. I’d remove and reinstall the driver packages.

The NVidia 750ti was a Maxwell generation card and the non-legacy driver should work. I have couple Maxwells with the “525-dkms” driver. You can therefore test both RPM Fusion and NVidia’s own build.

True. First, EL is much more “stable” than Fedora (as in smaller changes, even in point releases), so EL is “easier”.

The repos do have those “akmod” / “dkms” versions, where said tools supposedly can “rebuild” kernel module for new kernel versions. (Within limits of what the NVidia’s proprietary blobs allow.) The non-akmod/dkms version users have to wait until new kmod RPM is released for the new kernel version.
