In older versions of Ubuntu I used to be able to get a character based login screen by pressing Ctrl + Alt+ f1 (or F2 or F3...).
After I upgraded to 16.04 LTS this no longer works. All I get when I press Ctrl + Alt+ f1 is a dark, blank screen. (Using Ctrl+Alt+f7 to switch back to the graphical user interface works.)
How can I fix this?
EDIT
I was trying to experiment with @sudodus' comment below, but before I got that far, I discovered some strange behaviour.
- Sometimes I can get the consoles to work, but not always.
- Sometimes the consoles display a login prompt, but do not accept any input.
- Sometimes the computer locks completely when I press Ctrl+Alt+F1. (I can't event ssh to the computer from another computer.)
Perhaps what I really need is a fresh install... Sigh! :-(
EDIT
I just updated my computer from 4GB to 8GB of RAM. This solved the problem. (Confusing, I think; but I'm happy now.)
