WARNING: The following steps tell you to do "exactly" what you are asking. You will not be able to move any windows with your mouse because there won't be a window manager running. I advise you to at least have a window manager running so that you can move the windows or at least have a tiled window manager such as i3.
If you still wish to proceed despite this warning, follow these steps:

sudo apt install xterm

- Launch any program you want from there. To exit, type
- To re-enable GUI mode, type:
sudo systemctl set-default graphical.target
Special note: You may need to click inside the
