As root. "root" is the only account that exists after the initial installation (newer installation programs do prompt you to create a regular user account during the installation). Example text mode login:
my_machine_name login: root
In the example above, I typed the word "root" at the login prompt. After that, I entered the password that I chose during the initial Linux installation. The password did not appear on the screen when I typed it (for security). After I login, I find myself in a text-mode terminal.
If you installed the GUI login screen, the login procedure looks similar, but occurs on an X-window screen. (If you occasionally have problems typing there, perhaps position your mouse cursor above the dialog box. The X login screen may implement the "focus-follows-mouse" policy.) After a successful login, my default GUI desktop is launched.
"root" is a special account with an absolute power over the system, and it is used for system administration. You surely want to create at least one more "user" account later to do regular (not system administration) work. Read on to learn how to do it.[an error occurred while processing this directive]
