00:00:06,629 --> 00:00:10,369
In this video, I'd like to talk
a bit about the GNOME Display manager.

2
00:00:11,150 --> 00:00:16,679
So how about display managers? Well,
GNOME or GNOME is a display manager.

3
00:00:17,519 --> 00:00:23,304
It's the most commonly used display manager
on Linux and as such it provides a

4
00:00:23,304 --> 00:00:29,089
graphical interface for which programs can be
started in Windows or multiple virtual desktops.

5
00:00:30,629 --> 00:00:36,920
So GNOME is the most used display manager. Other display
managers are available as well, such as kde. The fact is

6
00:00:36,920 --> 00:00:43,210
that GNOME is used on Red Hat as well as
on Ubuntu. So in this video we'll focus on GNOME only.

7
00:00:44,170 --> 00:00:48,120
Now, working with differences between
display managers should be relatively easy

8
00:00:48,120 --> 00:00:52,070
as it is all about
clicking the appropriate graphical element.

9
00:00:53,170 --> 00:00:57,590
First thing you need to do before you
can work with the graphical interface is login.

10
00:00:58,679 --> 00:01:05,540
To do so, the GDM or GNOME Display Manager
process is used. It's a bit confusing because the

11
00:01:05,540 --> 00:01:12,400
GNOME Display Manager is the name for the entire
graphical packet, but also for the thing that takes

12
00:01:12,400 --> 00:01:19,260
care of logins. Specifically, GDM by default will
show users that have been defined on the system.

13
00:01:20,459 --> 00:01:23,420
And to login as a non
listed user, click the other item.

14
00:01:23,989 --> 00:01:27,614
That shouldn't be necessary too
often because GDM is pretty

15
00:01:27,614 --> 00:01:31,239
well capable of picking up
your current existing user accounts.

16
00:01:31,879 --> 00:01:34,689
After logging in, you will
get access to the GNOME shell.

17
00:01:35,390 --> 00:01:36,209
Let
me demonstrate.

18
00:01:38,109 --> 00:01:43,020
So here you can see what the
GDM login looks like and it's prompting

19
00:01:43,020 --> 00:01:47,930
for the password for the currently
only existing user on this Ubuntu system.

20
00:01:48,730 --> 00:01:52,439
So let me enter
the password and then

21
00:01:52,439 --> 00:01:56,150
it's bringing me
to the GNOME shell.

22
00:01:56,870 --> 00:02:02,754
So this is the very first time I'm starting this
interface. So this is giving the welcome to Ubuntu. I don't

23
00:02:02,754 --> 00:02:08,639
like this welcome to Ubuntu. So I'm clicking over it
and then we see what the interface is looking like.

24
00:02:09,620 --> 00:02:14,269
Now you might notice that the look and
feel of this GNOME shell in Ubuntu is

25
00:02:14,269 --> 00:02:18,919
slightly different from the way it shows
on CentOS, but the key elements are there.

26
00:02:19,909 --> 00:02:25,590
The thing that is different is that Ubuntu is
using this sidebar with a couple of commonly used applications.

27
00:02:26,289 --> 00:02:29,449
And on CentOS you just have
the menu in the upper left corner.

28
00:02:29,990 --> 00:02:35,145
So you click the menu and then you
get access to the bar where you can

29
00:02:35,145 --> 00:02:40,300
search the application that you want to work
with. More about that in the next videos.
