Time Narration
00:01 Welcome to this spoken tutorial on Ubuntu Linux Desktop.
00:06 In this tutorial we will learn about
  • Ubuntu Linux Desktop on the gnome environment
  • Some applications in Ubuntu Desktop
  • Changing the theme of the desktop
00:18 To record this tutorial, I am using Ubuntu Linux OS version 14.04
00:25 In some of the older versions of Ubuntu Linux, the desktop looks like this.
00:32 You can see Applications, Places and System tabs on the top left corner of the screen.
00:40 In the newer versions of Ubuntu Linux, the desktop looks likes this.
00:46 You'll see the launcher on the left hand side of the screen. If the launcher is hidden, as shown here, then we can make it visible.
00:55 To do so, move the mouse to the extreme left of the screen.The launcher will be visible.
01:02 Move the mouse away and the launcher will get hidden once again.
01:07 How can we make the launcher visible always? Click on the wheel icon at the extreme right corner of the desktop screen.
01:16 Now, click on System Settings and then on Appearance.
01:22 In the Appearance, click on Behavior tab.
01:26 Here, switch Auto-hide the Launcher to OFF position.Now, the launcher will be visible always.
01:35 Close this window.
01:37 Notice, there are some icons on the launcher, by default.
01:41 You can see the Dash home icon at the top of the launcher.
01:45 To open Dash home, click on it.
01:48 Right at the top, you'll see the search bar field.
01:52 Now, how do we locate a particular application? Its very simple!
01:58 Let’s try to locate the Calculator application.
02:02 So, in the search bar field, type C a l c.
02:06 See here, both LibreOffice Calc and Calculator are listed.
02:11 Click on Calculator icon.The Calculator application now opens on the screen.
02:19 In old versions of Ubuntu Linux, we have to click on Applications -> Accessories -> Calculator.
02:27 Calculator helps perform arithmetic, scientific or financial calculations.
02:33 Let us try some simple calculation.
02:37 Type 5 asterix 8 and press the equal to sign.
02:42 Instead of pressing equal to sign, you can also press the Enter key on the keyboard.
02:48 The answer is displayed on the Calculator.
02:50 Likewise, we can do all sorts of calculations using the Calculator application.
02:58 Now exit this Calculator by clicking the close button.
03:03 Let’s get familiar with a few other important applications of Ubuntu Linux OS.
03:08 For that, we will go back to Dash home.
03:12 Another way to open Dash Home is to press the Windows key on the keyboard.
03:18 So in the Search bar, type gedit.The Text Editor icon appears.Click on it.
03:25 In the old versions of Ubuntu Linux, we have to click on Application >> Accessories >> gedit.
03:33 What you see right now on the screen, is the gedit Text Editor window.
03:38 Let me type some text here.Type "Hello World".
03:43 To save the file, press Ctrl and S keys simultaneously on the keyboard.
03:49 Alternately, go to File and then click on Save.
03:54 Now, a dialog box named “Save as” opens up.It asks for filename and the location where the file has to be saved.
04:03 So let’s type the name as "hello.txt".
04:09 And for location let’s select Desktop and click on the Save button.
04:14 Let's close this gedit window now and check whether our file is saved on the Desktop or not.
04:22 Now on the Desktop, you can see the file hello.txt.This means our text file was saved successfully.
04:30 Let me open this file by double-clicking on it.See, our text file has opened with our written text.
04:39 The Internet has a lot of information on gedit Text Editor.There will be spoken tutorials on this topic at the below link.
04:49 Let's close this text editor and let's look at another application, Terminal.
04:55 So let's go to Dash home by pressing the Windows key.
04:59 Now type terminal in the search bar field.
05:03 Click on the Terminal icon.
05:06 In the old versions of Ubuntu Linux, we have to click on Application >> Accessories >> Terminal.
05:13 The terminal window opens on the screen.Please Note that the shortcut key to open the Terminal is Ctrl+Alt+T.
05:22 Terminal is called the command line.This is because you can command the computer from here.
05:29 In fact it is more powerful than the GUI.
05:33 Let me switch back to the Terminal window.
05:35 Now let’s type a simple command to get a feel of the terminal.Type 'ls' and press Enter.
05:44 You can see a list of all the files and folders in the current directory.
05:49 Here it is displaying files and folders from the Home folder.We will see later in this tutorial what the Home folder is.
05:59 We will not spend any more time with the terminal now.
06:02 Close the terminal.
06:05 Terminal commands are explained well in the Linux spoken tutorials series on this website.
06:12 Now, let's move onto another application i.e Firefox Web Browser.
06:17 Once again press the Windows key on the keyboard, to open Dash home. Type Firefox in the search bar.
06:25 Click on the Firefox Web Browser icon.
06:29 In the old versions, we have to click on Application -> Internet -> Firefox Web Browser.
06:35 Firefox Web Browser is used to access the world wide web.Now we can see that Firefox browser window is open.
06:45 Let’s go to the spoken-tutorial site.For that, go to address bar or press F6 on the keyboard.
06:52 I am pressing F6 now.And we are in the address bar.
06:58 Press backspace to clear any text visible in the address bar.
07:03 Now let’s type "http://spoken-tutorial.org".
07:13 As we type, Firefox may suggest a few possibilities.
07:18 You may choose one of these or type the complete address and press Enter.
07:24 Firefox will connect to the given website.
07:27 The Spoken Tutorial Homepage opens on the browser.
07:31 Let's close this and move on to the next application.
07:35 So, let's go to Dash home again and type office in the search bar.
07:41 You'll see various LibreOffice components like Calc, Impress, Writer and Draw.
07:48 In the old versions of Ubuntu Linux, we have to click on Application >> Office.
07:55 Excellent tutorials for all these components are available on the Spoken Tutorial website.
08:01 Now let's explore the Video option.
08:04 Go to Dash home and type video.
08:07 In the displayed list, we have one important application, Videos.
08:13 Videos is used to play videos or songs.By default, it plays open format video files only.
08:22 In the old versions of Ubuntu Linux, we have to click on Application >> Sound & Video.
08:28 Here we can see various applications and here is the application Movie Player.Click on it.
08:36 Let me play a sample file from my pen-drive.
08:39 Now, I am inserting my pen-drive in a usb slot on my machine.The pen-drive folder has opened automatically.
08:48 If it doesn't open, we can access it from the launcher.
08:54 Locate the pen-drive icon at the bottom of the launcher.
08:58 If we click on it, it shows the files and folders available on the pen-drive.
09:04 Now I will select the movie file to play i.e big-buck-bunny.ogv.
09:10 Here is my file; now I will double-click to open it.
09:14 It opens in Videos, by default.
09:18 Let's stop playing the movie.
09:22 In the older versions of Ubuntu Linux, the pen-drive will be visible on the Desktop.
09:27 In newer Ubuntu versions, press Ctrl, Windows and D keys, to go to the Desktop directly.
09:35 In older Ubuntu versions, the required key combination to go to the Desktop used to be either Ctrl, Alt, D or Windows key and D
09:45 The user must be prepared to handle such variations from version to version.
09:51 Let us now press Ctrl, Windows and D keys to go to the Desktop.
09:57 Now let's see some more important things on this desktop.
10:01 Notice the folder icon present in the launcher.
10:04 Let's click on it.The Home folder opens.
10:09 In the old versions of Ubuntu Linux, we have to click on Places >> Home Folder.
10:15 Every user has a unique Home folder in Ubuntu Linux.
10:20 We can say that the Home folder is "our house", where we can store our files and folders.
10:27 Unless we permit, others cannot see them.
10:33 More information on file permissions is available in the Linux spoken tutorials.
10:39 Let us switch back.In our Home folder, we can see other folders, such as…..
10:45 Desktop, Documents, Downloads,etc.
10:50 In Linux, everything is a file.Let’s open the Desktop folder by double-clicking on it.
10:57 Here, we can see that the same "hello.txt" file that we saved from the text editor.So this folder and the Desktop are the same.
11:08 Let me close this now.
11:10 Aren't you bored of seeing the same theme of the desktop? Let's change it.
11:15 Go to Dash home and type system settings in the search bar field. Then click on the system settings icon.
11:24 Alternately, click on the wheel icon at the top right of the desktop screen.Click on System Settings and then on Appearance.
11:35 In the previous Ubuntu Linux versions, we have to go to System ->Preferences ->Appearance.
11:42 The Appearance window opens up.
11:44 Here under Themes tab, we have many pre-installed themes.
11:50 Play with these themes as per your preference.
11:54 As soon as you click on that, you can see that changes have been applied on your desktop.
12:00 You can see it clearly by pressing Ctrl+Windows+D keys simultaneously.
12:08 That’s all for this tutorial. Let us summarise.
