Starting Graphic Interface

Ok, I'm not a complete newbie, just very rusty. I worked with unix years ago and can cd,ls,etc ok. Now I am working with a linux (centos) server through a vpn connection and putty to get a text window through which I login. I have a couple of questions:

1. How to determine if a graphical interface is installed?
2. If so, how to get it started?
3. If not, how to install a graphical interface?

starting gui

depends on the distros
Most of the times it is 'startx' even for a non root account.
To check if GUI is installted try 'whereis X'
hope this helps

My distro is centos, allegedly a free distro of RedHat. I ran startx as root and it returned
[root@wec-hou20 Documents]# startx
xauth: creating new authority file /root/.serverauth.1764

Fatal server error:
Server is already active for display 0
If this server is no longer running, remove /tmp/.X0-lock
and start again.

Please consult the CentOS support
for help.

Which, it seems to say is the server is already running.

So, the next step is to get kde or gnome runing? Also, how to find our how to set display back through my vpn tunnel to my local machine?

The startx command shouldnt be issued as root.

Here is a link on how to get Gnome in CentOS

you really should start x running as a normal NON root user
CentOS 6.5( the current) will not stop you .But it will fill up the server logs with a ton of warning messages
and you DO need FULL!!! root access " su -" or "su -l root"

otherwise you WILL get an error

you also have a lock file in place stopping you
from the error you posted
" /tmp/.X0-lock"
remove it as the error message recommends
