I do know of a brute-force workaround - discovered from the ‘pstree’ command. Find the process that started the Xorg X11 server’s display manager, and kill that prosess. On the Fedora 33 Xfce spin LiveCD, that process is the ‘lightweight Display Manager’ “lightdm”. It was started via systemd, so I killed it with ‘systemctl stop lightdm.service’. I could then use the keyboard hot-key [Ctrl]+[Alt]+[F2] to get to a virtual login on tty2. It would be great if I didn’t have to resort to something as brute-force as this, and would appreciate suggestions to get the LiveCD boot to just go to command-line / text-terminal mode in the 1st place…
