So I'm running Ubuntu 20. LTS. It opens to the graphic screen.

What I'd like:

  1. Boot up into terminal mode.
  2. Execute a command to start graphic mode.
Once graphic mode is started, can I exit back out?

Also, during installation, it never prompted me for a root password. Is there still a root account?
