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.
