 looking through the site it says something about the $DISPLAY variable but when i echo $DISPLAY i get nothing.
 
 I have amended the sshd_config file to allow x forwarding. I am using scp to connect through on my laptop. I get the same errors when on the host server and use a terminal window to connect to it.
 
 2) when i try and VNC through i get failed to connect, the VNC server is running on my virtual server, but am a bit confused as to why it is not working.
 
 3) is there a way to log into the virtual server with any graphical elements? for instance Gnome or KDE?
 
 
 Really frustrating so any help would be greatly appreciated.
 
 Thanks
