In this video, I'd like to talk a bit about the GNOME Display manager.
So how about display managers? Well, GNOME or GNOME is a display manager.
It's the most commonly used display manager on Linux and as such it provides a
graphical interface for which programs can be started in Windows or multiple virtual desktops.
So GNOME is the most used display manager. Other display managers are available as well, such as kde. The fact is
that GNOME is used on Red Hat as well as on Ubuntu. So in this video we'll focus on GNOME only.
Now, working with differences between display managers should be relatively easy
as it is all about clicking the appropriate graphical element.
First thing you need to do before you can work with the graphical interface is login.
To do so, the GDM or GNOME Display Manager process is used. It's a bit confusing because the
GNOME Display Manager is the name for the entire graphical packet, but also for the thing that takes
care of logins. Specifically, GDM by default will show users that have been defined on the system.
And to login as a non listed user, click the other item.
That shouldn't be necessary too often because GDM is pretty
well capable of picking up your current existing user accounts.
After logging in, you will get access to the GNOME shell.
Let me demonstrate.
So here you can see what the GDM login looks like and it's prompting
for the password for the currently only existing user on this Ubuntu system.
So let me enter the password and then
it's bringing me to the GNOME shell.
So this is the very first time I'm starting this interface. So this is giving the welcome to Ubuntu. I don't
like this welcome to Ubuntu. So I'm clicking over it and then we see what the interface is looking like.
Now you might notice that the look and feel of this GNOME shell in Ubuntu is
slightly different from the way it shows on CentOS, but the key elements are there.
The thing that is different is that Ubuntu is using this sidebar with a couple of commonly used applications.
And on CentOS you just have the menu in the upper left corner.
So you click the menu and then you get access to the bar where you can
search the application that you want to work with. More about that in the next videos.
