Just a quick tip on how to remove the root user from the PCLinuxOS login screen. This should work for most if not all KDE based distributions.
Go to the Kmenu >> Run Command >> kdesu kcontrol
Enter your root password when prompted for it. You should now see the KDE Control Center. The difference here is that you’re running this as the root user so changes will be made at the root (super user) level. Go to System Administration >> Login Manager. You should have something similar to the screenshot.
Next up, go to the ‘Users’ tab and look in the center. There you can see all the system users. Check the box for root. This will hide the root user from the front KDM Login Screen. This won’t prevent you from logging in as root, but it will prevent it from displaying by default.
