Hello and welcome,
Moved you comment to a dedicated topic so we can try to help you sort that issue.
First we need some more information about your setup/hardware, see @cscs instructions above.
In case you want to move forward, see here:
and also check the solution from the other OP.
Start with:
Option "ConnectToAcpid" "Off"
Option "metamodes" "nvidia-auto-select +0+0 {ForceFullCompositionPipeline = On}
first and then, depending on DE you use (since you mentioned fedora, i guess Gnome) things can be taken further.
