| 00:01 | Hello and welcome to this spoken tutorial on Ubuntu Linux Desktop 16.04. |
| 00:09 | In this tutorial we will learn about Ubuntu Linux Desktop on the gnome environment |
| 00:17 | And some common applications on the Ubuntu Desktop |
| 00:22 | To record this tutorial, I am using Ubuntu Linux 16.04 O S. |
| 00:29 | The Ubuntu desktop looks like this. |
| 00:33 | You'll see the launcher on the left hand side of the screen. |
| 00:37 | How can we hide the launcher? |
| 00:40 | To do so, go to the launcher on the left side.
Click on the System Settings icon. |
| 00:47 | In the System Settings window, click on Appearance. |
| 00:51 | In the Appearance window, click on the Behavior tab. |
| 00:56 | Here, switch Auto-hide the Launcher to ON position. |
| 01:01 | Now, the launcher will be hidden. |
| 01:04 | If the launcher is hidden, as shown here, then we can make it visible again |
| 01:10 | To do so, move the cursor to the extreme left of the screen. |
| 01:15 | The launcher will become visible. |
| 01:18 | Move the cursor away and the launcher will get hidden again. |
| 01:23 | Switch back to the Appearance window and turn Auto-hide the Launcher to OFF position. |
| 01:30 | Close this window by clicking on the tiny X icon at the top left of the window. |
| 01:37 | Notice, there are some icons on the launcher, by default. |
| 01:42 | At the top of the launcher, you can see the Dash home icon. |
| 01:47 | Dash home is an interface which gives access to all applications in Ubuntu Linux, within a screen. |
| 01:55 | To open Dash home, click on it. |
| 01:59 | Prominently at the top, you'll see the search bar field. |
| 02:04 | Now, how do we locate a particular application? Just type in the name of the application you are looking for and you will find it instantly
It's that simple! |
| 02:16 | Let’s try to locate the Calculator application. |
| 02:20 | So, in the search bar field, type C a l c. |
| 02:26 | All the applications that have c a l c in their name, will be listed. |
| 02:32 | Observe here - both LibreOffice Calc and Calculator are listed. |
| 02:37 | Click on the Calculator icon.
The Calculator application now opens on the screen. |
| 02:45 | Calculator helps perform arithmetic, scientific or financial calculations. |
| 02:52 | Let us try some simple calculation. |
| 02:55 | Type 5 asterix 8 and click on the equal to sign. |
| 03:02 | Instead of clicking on the equal to sign, you can also press the Enter key on the keyboard. |
| 03:09 | The answer is displayed on the Calculator. |
| 03:13 | Likewise, we can do all sort of calculations using the Calculator application. |
| 03:20 | Now exit this Calculator by clicking on this tiny X icon at the top left of the window. |
| 03:28 | Let’s get familiar with some other important applications in Ubuntu Linux OS. |
| 03:34 | For that, we will go back to Dash home. |
| 03:38 | In the Search bar, let’s type gedit. gedit is the default Text Editor in the Ubuntu Linux OS. |
| 03:48 | The Text Editor icon appears below. Let’s click on it to open it. |
| 03:55 | What you see right now on the screen, is the gedit Text Editor window. |
| 04:00 | Let me type some text here.
For example, type "Hello World". |
| 04:07 | To save the file, press Ctrl and S keys simultaneously on the keyboard. |
| 04:14 | Alternately, we can click on File and then on Save. |
| 04:20 | Now, a dialog box named “Save as” opens up.
It asks for a filename and the location where the file has to be saved. |
| 04:31 | So let’s type the name as "Hello.txt". |
| 04:36 | .txt is the default extension of a text file. |
| 04:41 | And for location, let’s select Desktop.
And click on the Save button at the bottom. |
| 04:49 | Let's close this gedit window now by clicking on the tiny X icon at the top left of the window. |
| 04:57 | On the Desktop, we can see the file Hello.txt.
This means our text file was saved successfully. |
| 05:05 | Let me open this file by double-clicking on it. |
| 05:09 | See, our text file has opened with our written text. |
| 05:14 | The Internet has a lot of information on gedit Text Editor. |
| 05:19 | There are some spoken tutorials available on this topic also, on this website. |
| 05:25 | Let's close this text editor and look at another application i.e the Terminal. |
| 05:32 | So let's go to Dash home, once again.
Now type the word terminal in the search bar field. |
| 05:41 | Click on the Terminal icon, that appears below. |
| 05:45 | The terminal window opens on the screen.
Please note: The shortcut to open the Terminal is Ctrl+Alt+T keys. |
| 05:55 | The terminal is also called the command line.
This is because you can command the computer from here. |
| 06:02 | In fact it is more powerful than the GUI. |
| 06:06 | Let me switch back to the Terminal window. |
| 06:09 | Now let ’s type a simple command to get a feel of the terminal.
Type 'ls' and press Enter. |
| 06:18 | You can see a list of all the files and folders in the current directory. |
| 06:23 | Here, it is displaying files and folders from the Home folder. |
| 06:28 | We will see later in this tutorial what the Home folder is. |
| 06:33 | We will not spend any more time with the terminal now. |
| 06:37 | Close the terminal by clicking on the tiny X icon at the top left of the window. |
| 06:43 | Terminal commands are explained well, in the Linux spoken tutorial series on this website. |
| 06:49 | Now, let's move on to another application i.e Firefox Web Browser. |
| 06:55 | Once again, open Dash home. Type Firefox in the search bar. |
| 07:01 | Click on the Firefox Web Browser icon. |
| 07:05 | Firefox Web Browser is used to access the world wide web.
Now we can see that Firefox browser window is open. |
| 07:15 | Let ’s go to the spoken tutorial website.
For that, click on the address bar or press F6 on the keyboard. |
| 07:24 | Now let’s type "spoken-tutorial.org" and press Enter. |
| 07:31 | If you have Internet connectivity, then Firefox will connect to the given website. |
| 07:37 | The Spoken Tutorial Homepage opens on the browser. |
| 07:41 | Let's close this as explained earlier, and move on to the next application. |
| 07:47 | So, let's go to Dash home once again and type office in the search bar. |
| 07:53 | You'll see various LibreOffice components like
Calc, Impress, Writer and Draw |
| 08:01 | LibreOffice is the default office application in Ubuntu Linux OS. |
| 08:07 | Excellent tutorials for all these components are available on the Spoken Tutorial website. |
| 08:13 | Now let's explore the Video option. |
| 08:17 | Type video in the search bar. |
| 08:20 | In the displayed list, we have one application named Videos. |
| 08:25 | Videos is used to play videos and songs. By default, it plays open format video files only. |
| 08:34 | So let me play a sample file from my pen-drive. |
| 08:38 | Now I am inserting my pen-drive in a usb slot on my machine.
The pen-drive folder has opened automatically. |
| 08:47 | If it does not open, we can access it from the launcher. |
| 08:52 | Locate the pen-drive icon on the launcher. |
| 08:56 | If we click on it, it shows the files and folders available on the pen-drive. |
| 09:02 | Now I will select the movie file big buck bunny.ogv to play. |
| 09:08 | Here is my file. I will double-click on it, to open. |
| 09:14 | It opens in Videos, by default. |
| 09:17 | Let's stop playing the movie. |
| 09:20 | Let us now press Ctrl, Windows and D keys to go to the Desktop. |
| 09:26 | Now let's see some other important things on this Desktop. |
| 09:31 | Notice the folder icon present in the launcher. Let's click on it. |
| 09:37 | The Home folder opens. |
| 09:39 | Every user has a unique Home folder in Ubuntu Linux. |
| 09:44 | We can say that the Home folder is our house where we can store our files and folders.
Unless we permit, others cannot see them. |
| 09:56 | More information on file permissions is available in the Linux spoken tutorial series. |
| 10:03 | Let’s switch back.
In our Home folder, we can see other folders such as, Desktop, Documents, Downloads, etc. |
| 10:14 | In Linux, everything is a file.
Let ’s open the Desktop folder by double -clicking on it. |
| 10:21 | Here, we can see that the same "hello.txt" file that we saved from the text editor. |
| 10:28 | So this folder and the Desktop are the same. |
| 10:32 | Let me close this folder now.
That’s all for this tutorial. Let us summarise. |
| 10:39 | In this tutorial we learnt about, the Ubuntu Desktop, the launcher and some of the icons available on it |
| 10:49 | Few common applications like Calculator, Text Editor, Terminal, Firefox Web Browser, Videos and LibreOffice Suite components and the Home folder |
