Add 2: The keyboard responded in one of those glitched-screen-states (for some reason) and I could boot into another user with CTRL-ALT-BACKSPACE. There, I checked the lines in the .bashrc, and I had forgotten a space between the initial grep and $EMU. Although, when rebooting, the screen yet again glitches, and it won’t respond to my keypresses anymore. Huh.
