Chapter 2. Starting Novell Linux Desktop

IN THIS CHAPTER:

1 About Booting the NLD System and Logon Options

2 Log On to the System

3 About Logoff Options

4 Log Off the System from the Desktop

5 Shut Down the System from the Logon Manager

In this chapter we take a look at booting NLD, logging on to the system, and then logging off and shutting down the system correctly. You might think that turning the computer on and then logging on to the system would be straightforward—and it is—but there are some logon options that we need to explore.

First, to log on to the system you need a valid username and password. The user could have been created by you during the NLD installation process or by your network administrator if you didn't play a part in the NLD installation on the PC.

Note

You only have rights to change or add user accounts if you have the root password. So, if your account has been created for you, you won't be able to add users or change settings related to the user accounts.


Logging on to the system is straightforward after the user accounts have been established (particularly the user account you will use). You might also think that logging off and then turning off the system must really be a piece of cake; however, the Linux shutdown process can actually take some time as the various system processes are terminated . Pulling the plug (meaning turning off the power) on the system before the shutdown is complete can actually lead to corruption of the system files and loss of data. Let's take a closer look at the logon screen and logon options.

1. About Booting the NLD System and Logon Options

When you boot the NLD system, your computer initializes its hardware (such as the processor). Then a boot loader, a small program that resides on the root partition of your hard drive, begins to load the Linux kernel and passes control of the system over to Linux (in this case NLD). The boot loader program actually provides a text screen that allows you to select boot options such as a regular boot (Linux) or a boot to a floppy or failsafe boot, which provides a command line only.

Key Term

Boot— The process where a computer system is initialized , and an operating system is loaded.


The boot loader provides options for how you want the system to boot.

NLD then communicates with the computer's memory and other hardware components as it readies the system for use. As these events take place, the kernel writes them to the screen, so you will actually see messages related to hardware initializations and other boot events.

The NLD boot process is displayed as messages on the screen.

Tip

If you even bother to watch the boot messages you will probably find that they don't make compelling entertainment. However, you actually can get troubleshooting tips from these messages if there is a problem with your system. As the kernel displays a message for a particular boot task it then adds the "done" tag. In cases where hardware fails to initialize or other problems arise, a message will be followed by the "failed" tag.


After the system is loaded, the Logon Manager appears. This is where you enter your username and password to log on to NLD.

Enter your username and password in the NLD Logon Manager.

However, before walking through the actual logon process (which is only a couple of steps), let's briefly explore the options that the Logon Manager provides. These options come in the form of three menus :

  • Language— This menu allows you to select the language for your NLD session. The default language will be the language selected during the NLD installation. To change the language, make a selection and then click OK.

  • Session— This menu allows you to choose the GUI desktop that is loaded when you log on for this session. Choices include GUIs such as GNOME (the default desktop for NLD) and KDE. Two choices also are provided that can be used to troubleshoot problems with your NLD installation: Failsafe GNOME and Failsafe Terminal (the terminal provides a command shell only).

Note

Typically, you will want to use your default Session setting; this provides the desktop GUI you use on a regular basis (GNOME, for example).


  • Actions— This menu includes options for shutting down the computer, rebooting the computer, or configuring the Logon Manager. Select the appropriate option and then click OK to proceed. The configuration possibilities revolve around the look of the Logon Manager and allow you to change the "graphical greeter" from the default greeter to other greeters such as the Happy GNOME with Browser greeter. To change the configuration (including the graphical greeter screen), you must know the root password.

Other graphical greeters can be configured for the Logon Manager such as the Happy GNOME with Browser greeter.

Whether you take advantage of any of the configuration possibilities provided by the Logon Manager menus is really up to you. This book discusses NLD in terms of the installation defaults.
