Welcome to LQ!!
I am not quite sure what you are asking. In the typical Linux setup, there are 2 ways to have a terminal: 1) as a window in the GUI desktop, or 2) By switching to a text console using ctrl-alt-F1. By "graphical terminal", I'm guessing that you mean #1, but a terminal of any kind involves entering text (command-line interface)
What "display configuration program" are you talking about?
Also, please tell us what distro (version) of Linux you are using.
