I've written a tutorial explaining how to install Nvidia drivers in Fedora 30, covering Gnome Software, via command-line and manual compilation, including addition and enablement of third-party repositories, kmod and akmod packages, new and legacy driver versions, 32-bit libraries, and more. Have fun. https://www.dedoimedo.com/computers/fedora-30-nvidia-guide.html Cheers, Mrk
