Here is what I have in /usr/share/wayland-sessions:
gnome-wayland.desktop
gnome.desktop
plasma.desktop
So in THEORY when I sign in / login there SHOULD BE some sort of cog or gear that would allow me to switch between my DE. I SHOULD BE able to switch between KDE and GNOME at the very least. And I did install EPEL so that can not be it. The only thing I can think of is that I installed RL KDE 10.1 LIVE version and not the the the hardcore RL 10.1 version, but would be kind of silly. I still need to figure out HOW to switch between KDE and GNOME at the login. GNOME is installed!
