Full screen terminals can be useful for many reasons. I particullary like being able to use them for writing as I have little to distract me. However, using Ctrl+Alt+F1-F* (depends on your setup) can often be slow to switch back to a graphical environment. When you use Konsole, as in this tutorial, you can quickly use a keyboard command to switch back to another virtual desktop. Also, you get many of the great features of Konsole and possibly a better resolution to read text. Konsole is the default console for KDE, but it can be installed (with many libraries) under GNOME and such as well.

1. Open up Konsole.

2. Go to Settings > Full Screen Mode to get the full screen mode. Now you may wish to take the extra GUI elements off of the terminal.

3. Now you can clear other elements if you wish.

You can access the menu bar options again with the right click menu.

If you would like to save the session for the future, you can do this under Settings>Save Session Profile. You can later access it under Session>(the name you've chosen). This should hopefully give you a similar feel to using a tty, but more feature-rich and with quicker access.
