http://www.liberiangeek.net – Our goal here is to make our blogs as easy as it can be. This new series of tutorials about Introduction to Linux are geared towards those new to Linux. In our upcoming tutorials, we will explore Linux’s most popular distributions and introduce you to them in a very easy to read and easy to understand writing.   The first of these tutorials is an introduction to Ubuntu Linux. As you may already know, Ubuntu is one of the most popular distributions (version) of the Linux Operating System. It is easy to learn and manage, fast and has good support materials. I will recommend that you make it your first system to learn about Linux Operating System.   In this simple to read tutorial, I’ll show you how to configure your basic Ubuntu System after installing.  To learn how to install Ubuntu, read our previous blog Perfect Ubuntu Installation.   Some of the first things you do after installing a new operating system are updating your system with the latest patches, add a new printer, creating user accounts, installing/removing programs, changing the background and finding your way around your new system.   Step One) Updating your system: This is the first thing you do after installing any new operating system. In Ubuntu, Software Sources is where you setup update sources. To access Software Sources, click System –> Administration –> Software Sources.     On the Ubuntu Software tab is where you specify Ubuntu Software Sources. All software from Ubuntu are store in this location. Select the check boxes to enable. If you need to add software from other sources, select Other…       On the Other Software tab, click Add CD-ROM button to install from a CD-ROM or add other http sources. If you’re installing via http, you’ll need to complete source address of the repository.     On the Updates tab, check the types of updates to install. The first two are recommended. You can also choose to alert you when there’s a new upgrade available by choosing Normal releases in the Release upgrade option.     Once you’re done specifying the Software Sources, click System –> Administration –> Update Manager.     With your computer connected to the Internet, click the Install Updates button as shown below. This should take some time to complete. After updating, reboot your computer and login.       Step Two ) Managing User Accounts, Changing background/themes   As with any operating system, you’ll have to manage user accounts and configuring your system just the way you want it. Ubuntu is no different. To configure user and group accounts, click System –> Administration –> Users and Groups.     Click the key to assume the administrator’s role. This role allows you to make changes to the overall system.     Enter the Administrator’s password to continue.       Enter the user basic settings here. The username and password is what will get the user logged-in. Select the profile for the user. There are three profiles here: Desktop user, Administrator and Unprivileged.       Select the User Privileges tab and assign roles and rights to the user’s account. To deny access, uncheck the box next to the functions.     The Advanced tab is should usually be left alone. This specifies the user’s home directory, Shell and User ID. Once done click OK.       Background/Themes: You can also change the default background image and theme. To change it, click System –> Preferences –> Appearance     Theme: Choose a theme from the list to apply. To get more themes, click Get more themes online.     Background: Choose a background from the list to apply. To get more background, click Get more background online.     Visual Effects: Here you can configure 3D effects for you computer. If you system has a 3D graphic card install, configure the 3D effect here. Once complete, click close.     Access Firefox by going to Applications –> Internet –> Firefox Web Browser       That’s all for today. We’ll will continue with our series later with more tutorials about using other applications. Join the forum discussion on this post (HowTos)
