How to Disable the Nouveau Kernel Driver for NVIDIA Graphics Cards in Fedora 41

Step 1: Remove Existing NVIDIA Packages

If you’ve previously attempted to install NVIDIA drivers, it’s best to start with a clean slate:

sudo nvidia-installer --uninstall

Step 2: Install Required Packages for Kernel Building

sudo dnf install @base-x kernel-devel kernel-headers gcc make dkms acpid libglvnd-glx libglvnd-opengl libglvnd-devel pkgconfig xorg-x11-server-Xwayland libxcb egl-wayland

These packages are necessary for building kernel modules, which the NVIDIA installer will need to do.

Step 3: Create a More Comprehensive Blacklist

Edit the system’s main blacklist file:

sudo nano /etc/modprobe.d/blacklist.conf

Add these lines to block Nouveau thoroughly:

blacklist nouveau
blacklist lbm-nouveau
options nouveau modeset=0
alias nouveau off
alias lbm-nouveau off

Step 4: Create a Specific KMS Configuration

For extra assurance, create a dedicated file for disabling Nouveau’s kernel mode setting:

echo "options nouveau modeset=0" | sudo tee /etc/modprobe.d/nouveau-kms.conf

Step 5: Update the Initramfs and Reboot

sudo dracut --regenerate-all --force
sudo reboot
