Do you know what I like?
Turning up the font size on GNOME Terminal, removing the menu bar, and hitting F11 (obviously the first two steps are in the configuration).
It’s better than using a virtual terminal because black screens seem to reflect more and Ubuntu’s console doesn’t have Japanese fonts (as they say, X’s true purpose is higher resolution fonts).
P.S. I think I ate a cursed carrot of hunger today. In the end I decided to resurface with my trusty steed and without the Amulet of Yendor. I’m getting better at nethack, but my problem is that I have more important things to do. Maybe that isn’t a problem.
