The pc freezes after login, have to reboot for successful start up. RPMfusion, nvidia drivers, gdm, Gnome Workstation.

edit

I have tested the last week installing fedora 28 workstation on my SSD along side windows 10, my steps for installing rpmfusion nvidia driver was:

On the login screen(gdm) switched from Gnome(wayland) to Gnome with xorg.

I Installed the free and non-free repositories(fedora 22 and later)

$ sudo dnf install https://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm https://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm

Then updated the pc

$ sudo dnf update

Then uncommented "WaylandEnable=false" on /etc/gdm/custom.conf

Then rebooted the pc

Then I installed the rpmfusion nvidia driver (current GeForce/Cuadro/Tesla ), as my question inform I have a GeForce GT610 graphic card.

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

After reboot the pc, I can't pass the login screen (GDM) sucessfully, the screen get the same color of the GDM background and stuck it there forever. Any of the tty console works (ctrl+alt+fn). All kernel option that is showed by the grub2 have the same result.

To fix this problem you can change runlevel to 3 on GRUB2 (this modification is not permanent), now you will be inside your pc without a GUI interface, there you have to login with your user account name and your password. Now you can uninstall the nvidia driver, after that reboot the pc.

$ reboot

Now you will have the open graphic driver installed and the pc will be usable. If you don't want uninstall rpmfusion nvidia driver follow the steps below.

But now you can successfully solve the GDM issue.

The solution is change gdm(display manager) to another , for example lightdm. You must run your pc without a GUI interface, you could do that by change run level to 3 on GRUB2.

First you have to change runlevel to 3
Login with your user name account and password.
Then install lightdm

$ sudo dnf install lightdm

Now disable gdm.service and enable lightdm

$ sudo systemctl disable gdm.service
$ sudo systemctl enable lightdm

Stop gdm and start lightdm

$ sudo systemctl stop gdm
$ sudo systemctl start lightdm

Then reboot your pc

$ reboot

thanks pals, greetings from Ecuador, you could use open drivers but if you like to install proprietary driver , it is possible on fedora 28 workstation.
