Installing lightdm from the stenscorp/lightdm was indeed the fix.

Now my desktop is back to looking and working like it's supposed to be.

For the next guy who needs to do this, here are the exact commands needed:

dnf copr enable stenstorp/lightdm
dnf install lightdm
systemctl disable gdm.service
systemctl enable lightdm.service

Then reboot.  You'll probably have to select Mate from the drop-down list at the top right of the login screen but you only have to make that selection once.

Thank you ever so much for the help, Greg!
