I couldn't get mousepad to open.
I went to the linux-tui option, on the login screen, I typed "root", then my password, and everything seemed fine.
Then, with any way that I tried to open the mousepad text editor, I got this error message:
(mousepad: 3050 [this number changed every time]): Gtk-WARNING **: cannot open display:
The text in the terminal works fine though, so the video problem must be specific to the GUI
