With gdm the gear only shows up if you have more than one whatever.session file in /usr/share/xsessions. gnome-classic-session and gnome-session-xsession provides this file for gnome sessions, mate-session-manager provides it for mate, and I don't know what provides it for kde.
lightdm is a lot more configurable than gdm, and it's easy to use that instead:
systemctl disable gdm
systemctl enable lightdm
systemctl isolate graphical.target
Then you can easily configure /etc/lightdm/lightdm-gtk-greeter.conf to do pretty much what you want it to do. I haven't yet figured out how to get rid of the blank photo man beside the password prompt, though.
