After install fedora 44 NVIDIA drivers failed to load and it falled back to nouveau

This card isn’t supported by the latest Nvidia 595 drivers on RPMFusion for Fedora 44.

You can remove those and install the 580 drivers, which do still support your card:

sudo dnf remove "*nvidia*" --exclude nvidia-gpu-firmware
sudo dnf install akmod-nvidia-580xx xorg-x11-drv-nvidia-580xx-cuda 

Then wait a few minutes for the drivers to build, then reboot.
