  • With gnome there is a “gear wheel” on the password entry page — on the right below the password box, next to the “sign in” label. If I
    select it I can switch between gnome and mate. Does KDE show there as an option?

    Fascinating. Not in ours. It displays our issue, and in the upper left, some icons that let you deal with sound, I think, connection, maybe, and I
    forget what else.

  • In my case the gear which when clicked of gives you drop down choices of Desktop Environments (DE) installed appears only after I click on particular user. In other words, when user has password field, he also has a gear to click on to choose DE.

    I hope, this helps.

    Ah, that was it, it’s not on the screen where you put in your username, it’s on the password screen. On the other hand, the easier solution was to just create /etc/sysconfig/desktop, which did not exist, and add the two lines to it.

    Thanks, folks.

  • 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.
