I believe that by default Centos uses the GDM Gnome login, even when you install KDE. I am running Centos6 with KDE, but I am quite certain that my login is still the default. Before upgrading this machine I was running Centos5, and I jumped through a bunch of hoops to enable the KDE login screen, KDM. I just checked, KDM is installed, but I am quite certain it is not enabled. Looking at my list of running programs, I find three that start with gdm- , even though I do not have Gnome installed. There is a very good chance you were using KDE tools to configure a non-functioning KDM. Your choices seem to be: Find the tools to configure the login manager you are actually running or Switch to KDM as your actual login manager. Here are a couple of links I checked: https://www.centos.org/docs/2/rhl-rg-en-7.2/s1-x-runlevels.html http://www.tldp.org/HOWTO/archived/KDE-GUI-Login-Configuration-HOWTO/ Ted Miller
