No KDE option in session menu

Hi All - I recently got a new desktop with Fedora 24 installed, and I am trying to install/configure KDE. I tried doing "dnf install @kde-desktop" as stated on https://fedoraproject.org/wiki/KDE#Installing_KDE_Plasma_Workspaces, but it said it was already installed: dnf install @kde-desktop Last metadata expiration check: 1:49:36 ago on Mon Nov 28 09:39:00 2016. Group 'KDE' is already installed, skipping. Dependencies resolved. Nothing to do. Complete! I then did some googling and tried the following: yum groupinstall "KDE Plasma Workspaces". This did install a bunch of packages, but after logging out the KDE option still does not show up in the session menu. Keeping with my shotgun mentality, I tried: yum install kdebase-workspace systemctl disable gdm systemctl enable kdm system-switch-displaymanager kdm But no change. Any help is greatly appreciated.. Thanks, Tom
