How do I change Fedora to SDDM from GDM?
You can use systemctl to switch to SDDM - first disable your current display manager. Do the switch like this:
systemctl disable gdm
systemctl enable sddm
Probably easiest to reboot after this.

Configuration file "/var/lib/sddm/.config/sddm-greeterrc" not writable is displayed when booting to KDE
I solved the issue by changing the owner of the /var/lib/sddm/.config/ directory recursively. The owner for the directory was root.
chown sddm:sddm /var/lib/sddm/.config -R
or
chown -R sddm:sddm /var/...

Similar to Xorg.0.log, this is your display manager’s log file. It is also safe to delete, and you’ll also need to restart your Deck.

How do I change Fedora to SDDM from GDM?
The Fedora answer is:
sudo systemctl enable --force sddm.service
This also aliases the display-manager.service to SDDM. After a restart GDM is disabled and SDDM became the default.
