I am not an avant-garde person, and dressing aesthetics is also a public eye. however, I only like to try the latest on the computer, and I am willing to be a mouse. recently, Ubuntu, a very famous release version in linux, has been installed. Ubuntu 12.04 is a long-term supported version. It is officially announced to support this version for 5 years.

Ubuntu 12.04 uses the unity interface by default, but prefers GNOME 3.

Install gnome3:

Sudo apt-get install gnome-shell

In fact, after the installation is successful, log out of the system and select GNOME on the logon interface. after entering the system, it is the GNOME3 interface. however, due to system cleaning, you always want to uninstall the unity interface. set the Default Login desktop environment to GNOME3.

Use the gnome3 interface to log on to the system and set it as the default logon environment:

Sudo/usr/lib/lightdm-set-defaults-s gnome-classic

Sudo/usr/lib/lightdm-set-defaults-s gnome-shell

In a strange way, you always want to uninstall Unity:

Sudo apt-get-y -- auto-remove purge unity

Sudo apt-get-y -- auto-remove purge unity-commonp

Sudo apt-get-y -- auto-remove purge unity-lens *

Sudo apt-get-y -- auto-remove purge unity-services

Sudo apt-get-y -- auto-remove purge unity-asset-pool

After logging on to the system again, the default interface is the GNOME3 interface, and the unity and unity2d options are no longer available in the selected desktop project.

Configure the GNOME3 interface further:

First, you need to install a tool to facilitate management, installation of themes and desktop settings.

Sudo apt-get installgnome-tweak-tool

The most popular Icon topic is Faenza Icon Theme.

Sudo add-apt-repository ppa: tiheum/equinox

Sudo apt-get update

Sudo apt-get install faenza-icon-theme

After installation, in System Tools-advanced settings, set the icon to faenza.

Note: GNOME Shell is an important part of GNOME 3. It provides window switching, opening applications, and other functions. Together with the window manager, it forms the GNOME 3 desktop we see.

The gnome-shell version used in Ubuntu 12.04 beta is 3.3.92, so there are some themes and extensions for gnome-shell 3.2 that cannot be used currently. however, when Ubuntu 12.04 is officially released, all these problems should be solved.
