Are you actually using KDE login? 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:
