Install GNOME/KDE Desktop Environment on Ubuntu or CentOS

The linux operating system is the most popular open source operating system. In 1991, Linux Torvalds started works on this project and later he was able to successfully create linux kernel. With this open source operating system you can configure all type of server (DHCP, DNS, Mail, Web etc). We all know linux operating system is based on the complete command prompt. That is, there will be no graphical view. Complete server configuration will be done through command prompt. This makes linux administration a bit complicated. Later, for the convenience of the linux administrator, some graphical tools were created, which would make linux administration much easier after use. The most notable of these graphical tools is the graphical desktop environment. Among these desktop environments, the GNOME desktop environment and KDE desktop environment are the most popular. Ubuntu and CentOS are the two linux distributions that you can apply in order to install GNOME and KDE desktop environment.

First we will install GNOME and KDE desktop environment in CentOS. Of course, every command execute requires root privileges. So we logged in as root user.

Let's first install the KDE desktop environment.

[root@system ~]# yum update (optional command)

[root@system ~]# yum upgrade (optional command)

[root@system ~]# yum   -y   groupinstall   “KDE desktop” “X Window System” “Fonts”

[root@system ~]# startx (to run the graphical environment)

Now, let us install the GNOME desktop environment.

[root@system ~]# yum update (optional command)

[root@system ~]# yum upgrade (optional command)

[root@system ~]# yum   -y    groupinstall     “GNOME Desktop”

[root@system ~]# yum   -y    groupinstall     “X windows System” 

[root@system ~]# yum   -y    groupinstall     “Graphical Administration Tools”

[root@system ~]# startx       (to run the graphical environment)

Now, we will install KDE and GNOME desktop environment in Ubuntu.

Let's first install the KDE desktop environment.

[root@system ~]# apt-get update (optional command)

[root@system ~]# apt-get -y upgrade (optional command)

[root@system ~]# apt-get   -y   install   kubuntu-desktop

[root@system ~]# reboot

Now let us install the GNOME desktop environment.

[root@system ~]# apt-get update (optional command)

[root@system ~]# apt-get –y upgrade (optional command)

[root@system ~]# apt-get   -y   install   ubuntu-gnome-desktop

[root@system ~]# reboot

After the installation complete, we can administrate our server graphically.
