No I don't want to boot default in text mode, the problem is that my screen turns blank after booting (when you see all the text with "done" etc.). I think it is because I forgot to test display settings during setup, so I wanted to do it from text mode. CTRL+ALT+F1 (CTRL+ALT+Fn+F1) doesn't work, neither does the second command, so I want to boot immidialtly to text mode from the bootloader, but don't know how.
