Lightweight Desktop Environments for Ubuntu 12.10/12.04

If you’re not happy with the default desktop environment (Unity shell on GNOME3) in Ubuntu 12.10 (Quantal Quetzal), then you can try installing some alternative desktop such as MATE, Cinnamon, KDE etc or a lightweight desktop environment such as XFCE.

Why go for a Lightweight Desktop Environment ?

  • speed
  • efficiency
  • low resource requirements (it can also run smooth on older computers)

1. XFCE

XFCE is a simple and easy to use Desktop environment with traditional layout/conventions (much like GNOME 2). The XFCE package contains desktop and some lightweight apps such as Thunar(File Manager), Ristretto (Image viewer), Midori (Web Browser), Orage (calandar app) etc. Based on XFCE, there is a seperate edition of Ubuntu – called Xubuntu.

Xfce Desktop

Installing XFCE Desktop in Ubuntu 12.10

sudo apt-get install xfce4

2. LXDE

LXDE is another lighteweight desktop environment. LXDE package includes the desktop environment and apps such as PCMan(File Manager), Leafpad (Text Editor), LXTerminal (Terminal Emulator), Openbox (Window Manager) etc. LXDE flavor of Ubuntu is Lubuntu.

4. GNOME Classic

GNOME classic edition (gnome session fallback) is based on GNOME3 but it has look and behavior very similar to GNOME2. So GNOME2 fans may want to try this.

In Ubuntu 12.10, it’s there in package repository, by default. KDE plasma desktop and apps are bundled together in various ways. Choose something that suits you well, or just go with second one (kde-plasma-desktop, with minimal set of applications).

KDE standard

it contains KDE plasma desktop and standard set of applications such as Kate (default editor, like gedit), Konqueror (default web browser), Kget (Download Manager), KMail (email client), Dolphin (File Manager), Konsole (terminal) etc. To install standard package of kde, open a terminal and execute the command –

sudo apt-get install kde-standard

KDE Desktop Minimal

sudo apt-get install kde-plasma-desktop

KDE Netbook Minimal

As the name suggest, it’s more suitable for netbook users.

sudo apt-get install kde-plasma-netbook

KDE Full

If you want the complete package of apps, along with the core desktop environment (KDE Plasma), then it’s the best option for you (but it may take more time to install depending on your internet speed).

sudo apt-get install kde-full

That’s All, enjoy the cool charming look of KDE.
