Hi, I have just installed Fedora 21 from the server edition netinstall with Cinnamon as my sole DE and I really like it. The one thing that annoys me is that I can't figure out how to change the login screen background from the default clouds wallpaper that I don't really enjoy. I'm pretty sure the DM is GDM but I'm not positive, and none of the potential solutions I saw applied to my setup. Any help, or anyone at least know where the login manager settings are stored so I could look at them?

You can find out if you're running gdm by running this in a terminal: ps aux | grep gdm | grep -v grep If you see at least one line of output, you are; if you just get a prompt back with no output, you aren't.

After a lot of File System exploring, I discovered the dm was lightdm. The backgrounds are stored in /usr/share/backgrounds

Did you also figure out how to set the background?

To change the background for lightdm, use your favorite editor (as root) to edit /etc/lightdm-gtk-greeter.conf. By default, the line that specifies the background looks like this:


Put a # at the beginning of the line to make a comment out of it because that documents what you changed and what it started out with. Then, create a new line beneath it pointing to your new image. Save the file, log out and it should show the new image. If not, run this command as root and try again:

systemctl restart lightdm.service
