I use Lubuntu 16.04. My /etc/defaults/console-setup
says:
ACTIVE_CONSOLES="/dev/tty[1-6]"
yet when I Ctrl+Alt+F1, or F2, or F3 etc. - I only see a black screen with the top line saying: "/dev/sda1: clean 123/456 files, 654/321 blocks" - no login prompt. I can switch back with Ctrl+Alt+F7, but, still - why doesn't it work?
I'm running Kubuntu v16.04 - not the version that you are - but I had to modify
/etc/systemd/logind.conf
, uncommentNAutoVTs=6
and restart.
