I've tried both gdm and lightgdm but no matter what I do, I get logged in to Gnome Classic (No Effects). The terminal's transparency is a nuisance here and I completely do not want to work on anything until things start looking pretty again.
I just want to be able to use the proper Gnome shell when I select it.
The issue wasn't with the display managers but with gnome itself. I completely uninstalled gnome-shell and then logged in. I had lost both Unity and Gnome and wasn't able to use the computer.
I installed Gnome again via the tty terminal (Alt+F1) and now I'm working in the pretty environment again.
