The Easy Way to Switch to Linux
Connect to the Network
Getting your machine on the network is simple with Ubuntu, whether you use a wired connection or Wi-Fi. When you first boot, the only icon in your system tray at the top of the screen should be for networking. Simply click it, enter your SSID and WPA or WEP key (if necessary), and you’ll be on the network.
Finding and Installing Software. Some Wi-Fi cards, particularly ones with Broadcom chipsets, aren’t natively supported in Linux because the companies have foolishly refused to open source their firmware. Fortunately, Ubuntu now includes a utility that will walk you through downloading and installing the closed-source firmware for most of these cards once you run a software update.
There are two ways to install programs on your new Ubuntu machine. The simplest is to use the Add/Remove panel, which lets you see all the software available to you from Ubuntu software repositories on the Internet. Most apps include a useful description, so if you search for Photo Manager, you’re sure to find some worthy candidates.
Sometimes you’ll need to fire up the more powerful Synaptic Package Manager, which you’ll find in System > Administration. After entering your password, click the Reload button to make sure the list of available apps is up to date. Synaptic provides a powerful search and easy filters that will help you find all the details of the applications installed on your system. You can see what apps are installed and which have updates available. If you want to update a single program to the latest available version, Synaptic is the easiest way to do that—just search for the software package, right-click it, and select “Mark for upgrade.”
You’ll occasionally need to add a new repository to your Linux install. A repository is just a server that contains software that’s configured and ready to run on your machine. If you want to install apps that aren’t included by default with Ubuntu, you’ll need to enable other respositories. To add a respository, you’ll need its apt line, which gives the software manager all the info it needs to access the repository (we’ll include some throughout this article). Open Synaptic and click Settings > Repositories. Go to the Third-Party tab and click Add; then type the apt line, exactly as it appears, in the window. Click Add Source, then click Close.
