Are you asking how you would use GNOME remotely or on a local installation with a monitor plugged in? Either way you're going to have to install the gnome group first. You can get a listing of the groups with `yum grouplist` and then you should be able to install it with `yum groupinstall <group name>`. After that it's simply a matter of changing your default runlevel to 5 from 3 in /etc/inittab and rebooting the machine (the easy way to start X).

Is Gnome already installed?

I am getting the error below, what does it mean?
[B]
$ yum grouplist
Loaded plugins: rhnplugin, security
*Note* Red Hat Network repositories are not listed below. You must run this command as root to access RHN repositories.
Setting up Group Process
Error: No group data available for configured repositories[/B]

I think it is already installed, if i run the following command, it gives some info on packages installed

rpm -qa | grep gnome

The error you received was due to your server not being registered with the RHN (Red Hat Network). You'll want to run `rhn-register` to register your install to receive updates. If you already have gnome installed it may just be a matter of changing your runlevel. To determine what runlevel you're currently in you can run `who -r`. If you're not currently in runlevel 5 you'll want to change your default runlevel in `/etc/inittab`. For the time being you should be able to run `init 5` to be sure that runlevel 5 will automatically start X.

Over the years, I developed an elegant method that does not require running a command such as runlevel in order to determine if I'm in runlevel 3 or 5...
In the spirit of the holidays, I shall share my method with y'all...

Look to the left... Look to the right...
Q: Are you seeing white text on a black background?

Look up... Look down...
Q: Are you seeing white text on a black background?

If you answered Yes to any question, then you are in runlevel 3
If you answered No to any question, then you are in runlevel 5

Yes I am on run level 3

It sounds like your Gnome issue hasn't been resolved...

All of the commands must be run as root user so change to root:

Code:

su -

To be sure you will automatically boot to a graphics login, edit the file /etc/inittab
Look for the following entry and change this

Code:

id:3:initdefault:

to read this

Code:

id:5:initdefault:

After saving and exiting the editor, change your current runlevel (3) to the GUI (5) by running this command:

Code:

telinit 5

If you did all the above and still can't get a graphical login and you haven't registered your RHEL system, run the following command:

Code:

rhn_register

When it's registered or if it's already registered, run the following command:

Code:

yum groupinstall “GNOME Desktop Environment”

At this point, to get a graphical login, change to runlevel 3

Code:

telinit 3

then change to runlevel 5

Code:

telinit 5
