|For this purpose, I am using '''Ubuntu 10.10'''.  
+
| To record this tutorial, I am using '''Ubuntu Linux OS''' version '''14.04 '''

−
|What you are seeing now, is the Ubuntu Desktop.
+
| In some of the older versions of '''Ubuntu Linux''', the '''desktop''' looks like this.
 +
 
 
|-
 
|-
−
|00:24
+
| 00:32
−
|You can see the main menu on the top left hand side corner.
+
| You can see '''Applications, Places''' and '''System '''tabs on the top left corner of the screen.
 +
 
 
|-
 
|-
−
|00:31
+
| 00:40
−
|To open this, you can press Alt+F1 or go to '''applications''' and click on it.  
+
| In the newer versions of '''Ubuntu Linux''', the '''desktop''' looks likes this.
 +
 
 
|-
 
|-
−
|00:40
+
| 00:46
−
|The application menu contains all the installed applications in a categorized manner.  
+
| 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.
 +
 
 
|-
 
|-
−
|00:48
+
| 00:55
−
|In this applications menu, lets get familiar with some important applications.
+
| To do so, move the mouse to the extreme left of the screen.The '''launcher''' will be visible.
 +
 
 
|-
 
|-
−
|00:55
+
| 01:02
−
|So lets go to '''Applications->Accessories->Calculator'''.
+
| Move the mouse away and the '''launcher''' will get hidden once again.
 +
 
 
|-
 
|-
−
|01:04
+
| 01:07
−
|'''Calculator''' helps perform arithmetic, scientific or financial calculations.
+
| How can we make the '''launcher''' visible always? Click on the wheel icon at the extreme right corner of the '''desktop''' screen.
 +
 
 
|-
 
|-
−
|01:12
+
| 01:16
−
|Lets open this, click on Calculator.  
+
| Now, click on '''System Settings''' and then on '''Appearance'''.
 +
 
 
|-
 
|-
−
|01:18
+
| 01:22
−
|Let us try some simple calculation.  
+
| In the '''Appearance''', click on '''Behavior''' tab.
 +
 
 
|-
 
|-
−
|01:22
+
| 01:26
−
|Type: 5*(into)8 and press '=' sign.
+
| Here, switch '''Auto-hide the Launcher''' to '''OFF '''position.Now, the launcher will be visible always.
 +
 
 
|-
 
|-
−
|01:32
+
|01:35
−
|Instead of pressing '=' sign, you can also type the Enter key.
+
|Close this window.
 +
 
 
|-
 
|-
−
|01:39
+
|01:37
−
|Now exit this calculator by pressing the Close button.
+
| Notice, there are some icons on the '''launcher''', by default.
 +
 
 
|-
 
|-
−
|01:46
+
| 01:41
−
|Now let's look at another '''application'''.
+
| You can see the '''Dash home '''icon at the top of the '''launcher.'''
 +
 
 
|-
 
|-
−
|01:50
+
| 01:45
−
|For that go back to '''Applications''' and then go to '''Accessories'''.
+
| To open '''Dash home, '''click on it.  
 +
 
 
|-
 
|-
−
|01:59
+
| 01:48
−
|In '''Accessories''', let's open '''Text Editor'''. Click on it.
+
| Right at the top, you'll see the '''search bar '''field.
 +
 
 
|-
 
|-
−
|02:09
+
| 01:52
−
|So what you see right now on screen is the '''gedit Text Editor'''.
+
| Now, how do we locate a particular application? Its very simple!
 +
 
 
|-
 
|-
−
|02:16
+
| 01:58
−
|Let me type some text here and save it. Type "H-e-l-l-o W-o-r-l-d".  
+
| Let’s try to locate the '''Calculator''' application.
 +
 
 
|-
 
|-
−
|02:28
+
| 02:02
−
|To save it, I can press '''Ctrl+s''' or goto '''File''' and then click on '''Save'''. So let me go to File and then Save.
+
| So, in the '''search bar '''field, type '''C a l c'''.
 +
 
 
|-
 
|-
−
|02:45
+
|02:06
−
|Now a small dialog box comes up. It asks for filename and location in which the file has to be saved.  
+
| See here, both '''LibreOffice Calc''' and '''Calculator''' are listed.
 +
 
 
|-
 
|-
−
|02:56
+
| 02:11
−
|So let me type the name as "hello.txt" and for location I select it as Desktop and click on '''Save''' button.  
+
| Click on '''Calculator '''icon.The '''Calculator '''application now opens on the screen.
 +
 
 +
 
 
|-
 
|-
−
|03:15
+
| 02:19
−
|Let's close this '''gedit''' now and check whether our file is saved on desktop or not. So close this.
+
| In old versions of '''Ubuntu Linux''', we have to click on '''Applications -> Accessories -> Calculator.'''
 +
 
 
|-
 
|-
−
|03:24
+
| 02:27
−
|Now on the desktop you can see the file 'hello.txt'.  
+
| '''Calculator '''helps perform arithmetic, scientific or financial calculations.
 +
 
 
|-
 
|-
−
|03:30
+
| 02:33
−
|So our text file has got saved successfully.  
+
| Let us try some simple calculation.
 +
 
 
|-
 
|-
−
|03:35
+
| 02:37
−
|Let me open this file by double-clicking on it.
+
| Type '''5 asterix 8''' and press the '''equal to '''sign.
 +
 
 
|-
 
|-
−
|03:40
+
| 02:42
−
|Wow!! our text file is opened with our written text.  
+
| Instead of pressing '''equal to''' sign, you can also press the '''Enter '''key on the keyboard.
 +
 
 
|-
 
|-
−
|03:44
+
| 02:48
−
|The internet has a lot of information on '''gedit text editor'''.  
+
| The answer is displayed on the '''Calculator'''.
 +
 
 
|-
 
|-
−
|03:50
+
|02:50
−
|There will be spoken tutorials on this topic at http://spoken-tutorial.org also.  
+
| Likewise, we can do all sorts of calculations using the '''Calculator '''application.
 +
 
 
|-
 
|-
−
|04:00
+
| 02:58
−
|Let's close this text editor and let's see some application from accessories that is '''Terminal'''.
+
| Now exit this '''Calculator '''by clicking the close button.
 +
 
 
|-
 
|-
−
|04:12
+
|03:03
−
|So let's move back to '''Applications->Accessories''' and then '''Terminal'''.
+
| Let’s get familiar with a few other important applications of '''Ubuntu Linux OS'''.
 +
 
 
|-
 
|-
−
|04:19
+
| 03:08
−
|Terminal is called '''command line''' because you can command the computer from here.
+
| For that, we will go back to '''Dash home.'''
 +
 
 
|-
 
|-
−
|04:25
+
| 03:12
−
|In fact it is more powerful than the '''GUI'''.  
+
| Another way to open '''Dash Home''' is to press the '''Windows '''key on the keyboard.
 +
 
 
|-
 
|-
−
|04:30
+
| 03:18
−
|Now lets type a simple command to get a feel of terminal.  
+
| So in the '''Search bar, '''type '''gedit'''.The '''Text Editor '''icon appears.Click on it.
 +
 
 
|-
 
|-
−
|04:36
+
| 03:25
−
|So let's type 'ls' and press Enter.  
+
| In the old versions of '''Ubuntu Linux''', we have to click on '''Application >> Accessories >> gedit.'''
 +
 
 
|-
 
|-
−
|04:41
+
| 03:33
−
|You can see, it lists all the files and folders in the current directory.  
+
| What you see right now on the screen, is the '''gedit Text Editor '''window.
 +
 
 
|-
 
|-
−
|04:48
+
| 03:38
−
|So here it is displaying files and folders from '''home folder'''.  
+
| Let me type some text here.Type '''"Hello World"'''.
 +
 
 
|-
 
|-
−
|04:55
+
| 03:43
−
|We will see later in this tutorial what the '''home folder''' is.  
+
| To save the file, press '''Ctrl '''and '''S''' keys simultaneously on the keyboard.
 +
 
 
|-
 
|-
−
|05:01
+
| 03:49
−
|We will not spend any more time with the terminal now. Terminal commands are explained well in the '''Linux''' spoken tutorials in http://spoken-tutorial.org.
+
| Alternately, go to '''File '''and then click on '''Save'''.
 +
 
 
|-
 
|-
−
|05:17
+
| 03:54
−
|Close the terminal.
+
| Now, a dialog box named “'''Save as”''' opens up.It asks for '''filename '''and the location where the file has to be saved.
 +
 
 
|-
 
|-
−
|05:20
+
| 04:03
−
|Now let's move on next application i.e Firefox Web Browser. Let's open it.
+
| So let’s type the name as '''"hello.txt".'''
 +
 
 
|-
 
|-
−
|05:27
+
| 04:09
−
|For that go to '''applications-> Internet-> Firefox web Browser'''. Click on this.
+
| And for location let’s select '''Desktop '''and click on the '''Save '''button.
 +
 
 
|-
 
|-
−
|05:36
+
| 04:14
−
|Firefox is used to access '''world wide web'''. Now you can see that firefox is open.
+
| Let's close this '''gedit''' window now and check whether our file is saved on the '''Desktop '''or not.
 +
 
 
|-
 
|-
−
|05:43
+
| 04:22
−
|Let's go to '''gmail''' site here. For that go to '''address bar''' or press '''F6'''. I am pressing F6 now.
+
| Now on the '''Desktop,''' you can see the file '''hello.txt'''.This means our text file was saved successfully.
 +
 
 
|-
 
|-
−
|05:53
+
| 04:30
−
|Yup! I am in address bar and now I press '''Backspace''' to clear the address bar.  
+
| Let me open this file by double-clicking on it.See, our text file has opened with our written text.
 +
 
 
|-
 
|-
−
|06:00
+
| 04:39
−
|I type "www.gmail.com"
+
|The Internet has a lot of information on '''gedit Text Editor'''.There will be spoken tutorials on this topic at the below link.
 +
 
 
|-
 
|-
−
|06:04
+
| 04:49
−
|As I type, Firefox may suggest a few possibilities.  
+
| Let's close this '''text editor''' and let's look at another application, '''Terminal'''.
 +
 
 
|-
 
|-
−
|06:09
+
| 04:55
−
|You may choose one of these or type in the complete address and press Enter .  
+
| So let's go to '''Dash home '''by pressing the '''Windows''' key.
 +
 
 
|-
 
|-
−
|06:15
+
|04:59
−
|Firefox could connect to the website directly or it could ask for a '''login''' and '''password'''.  
+
|Now type '''terminal '''in the '''search bar '''field.
 +
 
 
|-
 
|-
−
|06:22
+
| 05:03
−
|Now let us type the '''username''' and '''password''' and press Enter.  
+
| Click on the '''Terminal''' icon.
 +
 
 
|-
 
|-
−
|06:36
+
| 05:06
−
|Now you can see '''gmail web page''' opened on the screen. So let's close this and move on to the next one.
+
| In the old versions of '''Ubuntu Linux''', we have to click on '''Application >> Accessories >> Terminal.'''
 +
 
 
|-
 
|-
−
|06:45
+
|05:13
−
|Now let's go to office menu i.e '''applications->Office'''.
+
| The '''terminal '''window opens on the screen.Please Note that the shortcut key to open the '''Terminal '''is '''Ctrl+Alt+T.'''
 +
 
 
|-
 
|-
−
|06:53
+
| 05:22
−
|Then, further in this office menu we have '''OpenOffice Word Processor, Spreadsheet''' and '''Presentation'''.  
+
|'''Terminal''' is called the '''command line.'''This is because you can command the computer from here.
 +
 
 
|-
 
|-
−
|07:03
+
|05:29
−
|There is a lot of information on these topics in Internet.  
+
|In fact it is more powerful than the '''GUI'''.
 +
 
 
|-
 
|-
−
|07:07
+
| 05:33
−
|Our website will also have spoken tutorials on these topics in the future.  
+
| Let me switch back to the '''Terminal '''window.
 +
 
 
|-
 
|-
−
|07:12
+
| 05:35
−
|Then let's explore Sound & Video menu. For that, go to '''Applications->Sound & Video'''.
+
| Now let’s type a simple command to get a feel of the '''terminal.'''Type ''''ls' '''and press '''Enter.'''
 +
 
 
|-
 
|-
−
|07:21
+
| 05:44
−
|In this we have one important application i.e '''Movie Player'''. It is used to play videos and songs. By default, it plays the '''open format video file'''s only.  
+
| You can see a list of all the files and folders in the current directory.
 +
 
 
|-
 
|-
−
|07:35
+
|05:49
−
|So, let me play one sample file from my '''pen-drive'''. Now, I am inserting my pen-drive in an '''usb''' slot. Pen-drive has opened.
+
|Here it is displaying '''files '''and '''folders '''from the '''Home '''folder.We will see later in this tutorial what the '''Home''' folder is.
 +
 
 
|-
 
|-
−
|07:48
+
| 05:59
−
|If it doesn't open, you can access it from the desktop.
+
| We will not spend any more time with the '''terminal''' now.  
 +
 
 
|-
 
|-
−
|07:53
+
| 06:02
−
|Let us click the icon at the bottom left hand corner. If we click on it, it shows only the Desktop. If we click this again, it shows the Desktop along with the files already open.
+
| Close the '''terminal.'''
 +
 
 
|-
 
|-
−
|08:08
+
| 06:05
−
|We can go to the Desktop also by pressing Windows key and D simultaneously. Please note that the required key combination to go to Desktop used to be '''Ctrl+Alt+D''' in the previous versions of Ubuntu. The user must be prepared to handle such variations from version to version. Let us now press Windows key and D.
+
|'''Terminal '''commands are explained well in the '''Linux''' spoken tutorials series on this website.  
 +
 
 
|-
 
|-
−
|08:37
+
| 06:12
−
|Here you can see that your pen-drive is present on the desktop.
+
| Now, let's move onto another application i.e '''Firefox Web Browser.'''
 +
 
 
|-
 
|-
−
|08:42
+
| 06:17
−
|Let's open it by double-clicking on it.
+
| Once again press the '''Windows''' key on the keyboard, to open '''Dash home.''' Type '''Firefox '''in the '''search bar'''.
 +
 
 
|-
 
|-
−
|08:46
+
| 06:25
−
|Now I select the movie file to play it i.e '''Ubuntu Humanity.ogv''' .
+
| Click on the '''Firefox Web Browser '''icon.
 +
 
 
|-
 
|-
−
|08:57
+
| 06:29
−
|Here is my file, now I double-click it to open it.
+
| In the old versions, we have to click on '''Application -> Internet -> Firefox Web Browser.'''
 +
 
 
|-
 
|-
−
|09:09
+
| 06:35
−
|It opens in movie-player by default. Let's close this.
+
| '''Firefox Web Browser '''is used to access the world wide web.Now we can see that '''Firefox browser '''window is open.
 +
 
 
|-
 
|-
−
|09:13
+
| 06:45
−
|Now let's see some more important things on this desktop.
+
| Let’s go to the '''spoken-tutorial''' site.For that, go to address bar or press '''F6 '''on the keyboard.
 +
 
 
|-
 
|-
−
|09:18
+
| 06:52
−
|For that let's go to '''Places''' menu this time. In this, we have the '''Home Folder'''.  
+
| I am pressing '''F6 '''now.And we are in the address bar.
 +
 
 
|-
 
|-
−
|09:27
+
| 06:58
−
|Let's open it. Click on '''Home Folder'''.  
+
| Press '''backspace '''to clear any text visible in the address bar.
 +
 
 
|-
 
|-
−
|09:29
+
| 07:03
−
|Every user has a unique '''home folder''' in Ubuntu.  
+
| Now let’s type '''"http://spoken-tutorial.org"'''.
 +
 
 
|-
 
|-
−
|09:34
+
| 07:13
−
|We can say that the '''home folder''' is "our house" where we can store our files and folders.  
+
| As we type, '''Firefox '''may suggest a few possibilities.
 +
 
 
|-
 
|-
−
|09:42
+
|07:18
−
|Unless we permit, others cannot see them. More information on '''file permissions''' is available on the '''Linux''' spoken tutorials available at http://spoken-tutorial.org
+
|You may choose one of these or type the complete address and press '''Enter.'''
 +
 
 
|-
 
|-
−
|09:56
+
| 07:24
−
|In our '''Home Folder''' , we can see other folders such as Desktop, Documents, Downloads, Videos etc.
+
| '''Firefox''' will connect to the given website.
 +
 
 
|-
 
|-
−
|10:08
+
| 07:27
−
|In '''Linux''', everything is a file. Lets open the Desktop folder by double clicking.  
+
| The '''Spoken Tutorial Homepage '''opens on the browser.
 +
 
 
|-
 
|-
−
|10:16
+
|07:31
−
|Hey, we can see that the same "hello.txt" file what we saved from text editor is here.  
+
| Let's close this and move on to the next application.
 +
 
 
|-
 
|-
−
|10:25
+
| 07:35
−
|So this folder and the Desktop are the same. Let me close this folder now.
+
| So, let's go to '''Dash home '''again and type '''office '''in the '''search bar.'''
 +
 
 
|-
 
|-
−
|10:31
+
| 07:41
−
|Aren't you bored to see the same theme of desktop? Let's change it.
+
| You'll see various '''LibreOffice '''components like '''Calc,''' '''Impress, Writer '''and '''Draw.'''
 +
 
 
|-
 
|-
−
|10:37
+
| 07:48
−
|For that go to '''System->Preferences->Appearance'''. Click on it.
+
| In the old versions of '''Ubuntu Linux''', we have to click on '''Application >> Office.'''
 +
 
 
|-
 
|-
−
|10:44
+
| 07:55
−
|Here under '''Themes''' tab, we have many pre-installed '''theme'''s. Let us select "Clearlooks".  
+
| Excellent tutorials for all these components are available on the '''Spoken Tutorial '''website.
 +
 
 
|-
 
|-
−
|10:52
+
| 08:01
−
|As soon as you click on that you can see that changes have applied to your machine.  
+
| Now let's explore the '''Video''' option.
 +
 
 
|-
 
|-
−
|10:58
+
| 08:04
−
|You can see it clearly by clicking the Desktop icon present at the bottom left hand corner. Let us go back to the folder by clicking this icon again.  
+
| Go to '''Dash home '''and type '''video'''.
 +
 
 
|-
 
|-
−
|11:10
+
| 08:07
−
|Play with these '''themes''' which ever you like and click on Close button to exit.
+
| In the displayed list, we have one important application, '''Videos.'''
 +
 
 
|-
 
|-
−
|11:18
+
| 08:13
−
|This brings us to the end of this tutorial.  
+
| '''Videos''' is used to play videos or songs.By default, it plays '''open format '''video files only.
 +
 
 
|-
 
|-
−
|11:21
+
| 08:22
−
|In this tutorial we learnt about the Ubuntu Desktop, the main menu and the other icons visible on the Ubuntu screen.  
+
| In the old versions of '''Ubuntu Linux''', we have to click on '''Application >> Sound & Video.'''
 +

+
| 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.
 +
 
 +
|-
 +

 +
 
 +
|-

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:

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.
