In Linux the procedure for obtaining an authorized use of the system is called “logging in”.
When you are on a workstation then you should have a login: prompt on the screen. If
the screen is blank, move the mouse around to make the monitor come back on. If there is no response, then
the monitor may be turned off. In that case turn on the monitor. Enter your user name at thelogin: prompt and then enter your password at the password: prompt. Your password
will not appear on the screen when typed.
