Unhappy Issue with GDM on CentOS 6.3. Cant install new login screen..

Hi Guys,

Am trying to change to log-in screen of my Cent OS 6.3 Machine.

Cant find an application to change it. So after some googling found out that it is controlled by GDM.

Cant launch GDM from commandline as well.

Please go through my out and please help on how to install a GUI.


[Sriram@localhost ~]$ gdm
gdm gdm-binary gdmflexiserver gdm-screenshot
[Sriram@localhost ~]$ gdm

** (gdm-binary:10565): WARNING **: Failed to acquire org.gnome.DisplayManager: Connection ":1.116" is not allowed to own the service "org.gnome.DisplayManager" due to security policies in the configuration file

** (gdm-binary:10565): WARNING **: Could not acquire name; bailing out

CentOS comes with a "GUI" if I'm not mistaken.

gdm is a service daemon.
You cannot just 'start' it by typing gdm.

Try logging in using Ctrl+Alt+F1 as root and once logged in, type
init 5
and let us know if the Graphical Login Manager is displayed.
