So how do we start applications from gnome?
Well, that can be done easily using the GNOME menu.
And alternatively you can use the search bar to type only a part of the name of the application that you want to start.
The activities menu provides access to elements that are not currently shown.
Let's go check it out.
So here we have the Ubuntu desktop. And in the Ubuntu desktop on the left, you see the applications that
are available. These are very common applications, but as I said, the most important one is this search bar.
If, for instance, I'm looking for power related settings, then I type power and then I see my power utilities.
But I also have this setting power your battery status and the power off settings. Well, that happens to be what I want.
So here I have my screen blank. By default it screen blanks after five minutes.
I don't like that at all. So I'm going to set that to never.
And then I can click it, I can close it so that it goes away.
Likewise, if I want to see the search bar, I go to the manual in the upper left corner
and in the search bar I type term for terminal. And there we go. Here is the terminal.
And then there is this applications menu that Ubuntu is hiding right here.
So I'm clicking Show Apps and here I can see all
the applications that are currently offered in this Ubuntu environment.
You want to start an application, just click it and use it.
Yay, that works. Now that is how it works on Ubuntu.
Let's check out for some differences on CentOS.
So here is the CentOS GDM.
As you can see, it's pretty similar to the Ubuntu gdm.
And let me get rid of this window.
And this is what the GNOME interface looks like. As you can see, it's pretty empty
and you need to click the menu on the top to see the different elements.
So on the bottom we can see the equivalent for the sidebar in Ubuntu with some commonly used applications.
And there is show apps, which is showing the applic,
which may or may not be grouped into different elements.
Then most important part is type to search. Well, here also I'm going for power
and hopefully you see that it's exactly the same backend that we are working with.
So in power. Likewise, screensaver. I'm setting it to never because I still don't like my screensaver.
Hey, let me go to the terminal. I'm starting the terminal and then what do I want to
do? Well, I want to go through the applications and I wanted to tell you about the different
desktops. Do you see that here on the left we have the desktop with Terminal open.
Here on the right we have a desktop with nothing.
And that means that I can start Firefox. Where is Firefox?
Let me type Fire and. Oh, apparently there's no Firefox installed. Well, then
for now I'm going to use a different application like the Files utility.
So now I have these two applications, the Files utility, as
well as my terminal, which are open on different virtual desktops.
As you can see, Virtual desktop number one and virtual desktop number two is currently hiding.
So we want to get back there. Well, click on the Activities menu. Look,
here we see these different virtual desktops. That allows you to switch easily.
That should be enough to get you started in
your GNOME graphical interface and help you starting applications.
