Here are the steps to create a remote X Terminal sesson to one of our Linux servers.
1.) Enable remote access in YaST
YaST, System, /etc/sysconfig editor, (desktop) (Display Manager)
DISPLAYMANAGER_REMOTE_ACCESS = YES
DISPLAYMANAGER_ROOT_LOGIN_REMOTE = YES
2.) From the client start tsclient and do a XDMCP session to your machine.
Voila, a remote X Terminal
Another way of starting remote X apps (displayed on your client machine) is simply
by using ssh -X hostname. You start the apps from the command line on the server
and output (X) is displayed on your client.
