1 00:00:06,639 --> 00:00:08,589 So how do we start applications from gnome? 2 00:00:09,369 --> 00:00:11,939 Well, that can be done easily using the GNOME menu. 3 00:00:12,820 --> 00:00:18,609 And alternatively you can use the search bar to type only a part of the name of the application that you want to start. 4 00:00:19,629 --> 00:00:23,739 The activities menu provides access to elements that are not currently shown. 5 00:00:24,550 --> 00:00:25,410 Let's go check it out. 6 00:00:26,910 --> 00:00:32,765 So here we have the Ubuntu desktop. And in the Ubuntu desktop on the left, you see the applications that 7 00:00:32,765 --> 00:00:38,619 are available. These are very common applications, but as I said, the most important one is this search bar. 8 00:00:39,359 --> 00:00:46,310 If, for instance, I'm looking for power related settings, then I type power and then I see my power utilities. 9 00:00:47,210 --> 00:00:53,289 But I also have this setting power your battery status and the power off settings. Well, that happens to be what I want. 10 00:00:53,939 --> 00:00:57,629 So here I have my screen blank. By default it screen blanks after five minutes. 11 00:00:57,629 --> 00:01:01,319 I don't like that at all. So I'm going to set that to never. 12 00:01:02,240 --> 00:01:05,939 And then I can click it, I can close it so that it goes away. 13 00:01:06,939 --> 00:01:12,379 Likewise, if I want to see the search bar, I go to the manual in the upper left corner 14 00:01:12,379 --> 00:01:17,819 and in the search bar I type term for terminal. And there we go. Here is the terminal. 15 00:01:18,920 --> 00:01:24,659 And then there is this applications menu that Ubuntu is hiding right here. 16 00:01:25,290 --> 00:01:29,219 So I'm clicking Show Apps and here I can see all 17 00:01:29,219 --> 00:01:33,150 the applications that are currently offered in this Ubuntu environment. 18 00:01:35,750 --> 00:01:39,510 You want to start an application, just click it and use it. 19 00:01:42,409 --> 00:01:45,420 Yay, that works. Now that is how it works on Ubuntu. 20 00:01:46,180 --> 00:01:48,909 Let's check out for some differences on CentOS. 21 00:01:50,879 --> 00:01:52,599 So here is the CentOS GDM. 22 00:01:53,700 --> 00:01:56,469 As you can see, it's pretty similar to the Ubuntu gdm. 23 00:01:57,409 --> 00:02:01,239 And let me get rid of this window. 24 00:02:02,519 --> 00:02:07,189 And this is what the GNOME interface looks like. As you can see, it's pretty empty 25 00:02:07,189 --> 00:02:11,860 and you need to click the menu on the top to see the different elements. 26 00:02:12,819 --> 00:02:18,469 So on the bottom we can see the equivalent for the sidebar in Ubuntu with some commonly used applications. 27 00:02:19,050 --> 00:02:22,564 And there is show apps, which is showing the applic, 28 00:02:22,564 --> 00:02:26,079 which may or may not be grouped into different elements. 29 00:02:28,479 --> 00:02:33,175 Then most important part is type to search. Well, here also I'm going for power 30 00:02:33,175 --> 00:02:37,870 and hopefully you see that it's exactly the same backend that we are working with. 31 00:02:38,449 --> 00:02:44,819 So in power. Likewise, screensaver. I'm setting it to never because I still don't like my screensaver. 32 00:02:45,759 --> 00:02:51,513 Hey, let me go to the terminal. I'm starting the terminal and then what do I want to 33 00:02:51,513 --> 00:02:57,266 do? Well, I want to go through the applications and I wanted to tell you about the different 34 00:02:57,266 --> 00:03:03,020 desktops. Do you see that here on the left we have the desktop with Terminal open. 35 00:03:03,060 --> 00:03:05,719 Here on the right we have a desktop with nothing. 36 00:03:06,280 --> 00:03:11,150 And that means that I can start Firefox. Where is Firefox? 37 00:03:11,750 --> 00:03:16,590 Let me type Fire and. Oh, apparently there's no Firefox installed. Well, then 38 00:03:16,590 --> 00:03:21,430 for now I'm going to use a different application like the Files utility. 39 00:03:22,009 --> 00:03:25,759 So now I have these two applications, the Files utility, as 40 00:03:25,759 --> 00:03:29,509 well as my terminal, which are open on different virtual desktops. 41 00:03:30,090 --> 00:03:36,509 As you can see, Virtual desktop number one and virtual desktop number two is currently hiding. 42 00:03:37,409 --> 00:03:42,240 So we want to get back there. Well, click on the Activities menu. Look, 43 00:03:42,240 --> 00:03:47,069 here we see these different virtual desktops. That allows you to switch easily. 44 00:03:48,610 --> 00:03:52,215 That should be enough to get you started in 45 00:03:52,215 --> 00:03:55,819 your GNOME graphical interface and help you starting applications.
