Second screen on nvidia card shows only "Booting Fedora Linux" line

Hi, I installed a GT-730 card to use it with a secondary screen. Followed the guide at https://rpmfusion.org/Howto/NVIDIA, basically by only

sudo dnf install akmod-nvidia xorg-x11-drv-nvidia-cuda

, rebooted the system and the secondary screen shows the POST, then the GRUB menu, then keeps showing the line beginning with “Booting Fedora Linux”, which never goes away. The primary display works as usual. The second screen is not listed in Gnome Settings. Can you help me to get it working, please?

Many thanks in advance for your help!

You installed the wrong driver version for the installed GPU.
Please remove those drivers with
sudo dnf remove \*nvidia\* --exclude nvidia-gpu-firmware
then install the proper drivers for that GPU as shown at Howto/NVIDIA - RPM Fusion after enabling the repo as shown at Configuration - RPM Fusion

The GT-730 gpu is a legacy version and cannot use the current drivers.
You also will only be able to use the X11 desktop with the nvidia drivers for that GPU. The 470xx driver version does not support wayland.
