Guided Exercise: Accessing the Command Line Using the Desktop

In this exercise, you will log in through the graphical display manager as a regular user to become familiar with the GNOME Standard desktop environment provided by GNOME 3.

Outcomes

You should be able to log in to a Linux system using the GNOME 3 desktop environment, and run commands from a shell prompt in a terminal program.

Ensure that the workstation virtual machine is running. Perform the following tasks on workstation.

  1. Log in to workstation as student using student as the password.

    1. On workstation, at the GNOME login screen, click the student user account. Enter student when prompted for the password.

    2. Click Sign In.

  2. Change the password for student from student to 55TurnK3y.

    Important

    The finish script resets the password for the student user to student. The script must be executed at the end of the exercise.

    1. The simplest approach is to open a Terminal window and use the passwd command at the shell prompt.

      In the virtual learning environment with visual keyboard, press the Super key twice to enter Activities overview. Type terminal and then press Enter to start Terminal.

    2. In the terminal window that displays, type passwd at the shell prompt. Change the student password from student to 55TurnK3y.

      [student@workstation ~]$ passwd
      Changing password for user student.
      Current password: student
      New password: 55TurnK3y
      Retype new password: 55TurnK3y
      passwd: all authentication tokens updated successfully.
  3. Log out and log back in as student using 55TurnK3y as the password to verify the changed password.

    1. Click the system menu in the upper-right corner.

    2. Select Student UserLog Out.

    3. Click Log Out in the confirmation dialog box that displays.

    4. At the GNOME login screen, click the student user account. Enter 55TurnK3y when prompted for the password.

    5. Click Sign In.

  4. Lock the screen.

    1. From the system menu in the upper-right corner, press the lock screen button at the bottom of the menu.

  5. Unlock the screen.

    1. Press Enter to lift the lock screen curtain.

    2. In the Password field, enter 55TurnK3y as the password.

    3. Click Unlock.

  6. Determine how to shut down workstation from the graphical interface, but Cancel the operation without shutting down the system.

    1. From the system menu in the upper-right corner, click the power button at the bottom of the menu. A dialog box displays with the options to either Restart or Power Off the machine.

    2. Click Cancel in the dialog box that displays.

Finish

On workstation, run the lab cli-desktop finish script to complete this exercise.

[student@workstation ~]$ lab cli-desktop finish

This concludes the guided exercise.
