I am starting a new virtualization project using kvm so as my host I wanted to use RedHat as the host operating system.

I downloaded CentOS 7.0 and installed it, it’s very slick. I installed off of the live disk, so I have a full desktop environment.

Here’s the first thing I’ve changed, I didn’t add a user, I’m logging-in as root and I wanted to get rid of the “not listed?” label and just have a text box to type the username in.

Create this file

vi /etc/dconf/db/gdm.d/00-login-screen

Add this content to that file:

[org/gnome/login-screen]
# Do not show the user list
disable-user-list=true

Run this command and restart X, I just rebooted

dconf update
