What is linux gui?

Graphical User Interface (GUI)

##Introduction

Linux's graphical user interface (GUI, desktop, desktop environment) is a system-independent component, which may or may not be present

Usually used in servers Most Linux distributions will not install GUI, but operate through shell

The installation files of most Linux distributions have GUI, which can be selected on demand in the system installation interface, or can be installed later through shell

Rich GUI

It is precisely because the GUI of Linux is independent of the system that

many rich GUIs appear for us to use, For example, Gnome, KDE, Unity, MATE, XFCE, etc., they can be installed and used in most Linux distributions. Users can install and switch different GUIs in the same Linux to experience until they find their favorite.

Among the many GUIs, Gnome (

/noʊm/) and KDE are the two most popular. Both CentOS and Ubuntu use Gnome as the default GUI

Tuo: Ubuntu gave up Gnome in version 11.04 and used its own Unity as the default GUI (in order to bring Ubuntu into the mobile phone, tablet-mobile terminal field), and then gave up Unity and returned to Gnome in version 17.10. (The major version number of Ubuntu is the year, and the minor version number is the month. For example, 18.04 means the version released in April 2018)

##GnomeMy VMware happens to have three virtual machines: CentOS 6.10, CentOS 7, and Ubuntu18.04.4. Their default GUIs are all Gnome

(the Gnome versions of CentOS7 and Ubuntu18.04.4 are both 3.28.2. See It comes out: using the same GUI on different Linux distributions, the interface is the same)

① Ubuntu 18.04.4(gnome version is 3.28.2 )

Very nice

② CentOS 7(gnome version is 3.28.2)

CentOS7 enters the Gnome classic interface by default. You can click the small gear on the login interface to switch)

Gnome classic interface

(Gnome version is 3.28.2 ), press the win key to display the dock bar
##Gnome new version interface

(Gnome version is also 3.28.2)

This is the same as Ubuntu above, both It is a new version of Gnome's UI (different from Ubuntu in the following: the desktop does not display the dock bar by default (press the win key or click "Activities" in the upper left corner to display it), there are no icons, there is no option to enter the terminal when right-clicking, and the UI has no animation effects .This should be because the initial settings of Gnome in the CentOS installation package are like this. If the user does not like it, he can set it up as needed)

##③ CentOS 6.10

(View version through gnome-about is 2.28.2)

A more traditional UI, not as designed as the 3.x version
