## Debian, Derivates ##

### Debian ###

The stable release of LXQt is available in Debian's official repositories as of Debian 9 "stretch" which represents the testing distribution as of 11/2015. There are metapackages `lxqt-core` providing core features and `lxqt` providing LXQt as a whole plus some additional applications.

### Siduction ###

Siduction used to provide repositories which could be used on Debian as well earlier but these have been abandoned in favour of the official Debian repositories.

### Ubuntu, Derivatives ###

#### official repositories ####

LXQt is available in the official repositories as of Ubuntu 16.04 "Xenial Xerus". Note the current release 0.11 hasn't been included in Ubuntu so far and is expected to be available in 17.04. only.  
The metapackages are the same as in Debian.

#### PPAs ####

Aside from the official repos two PPAs exist. Note that both are subject to serious dependency issues on a regular basis and have to be considered experimental. They definitely cannot be recommended for usage on production systems.

In detail the repositories are

*  ppa:lxqt/ppa: Latest stable release. Provided by team "LXQt team", see[https://launchpad.net/~lxqt][https_launchpad.net_lxqt]. Metapackages `lxqt` and `lxqt-core` similar to those from the official Debian repositories are available.
 *  ppa:lubuntu-dev/lubuntu-daily: VCS snapshots updated on a regular basis. Provided by team "Lubuntu Developers Team", see [https://launchpad.net/~lubuntu-dev][https_launchpad.net_lubuntu-dev]. A metapackage `lxqt-metapackage` pulling all essential components is available.

LXQt developed from popular components of LXDE and Razor Qt project, LXQt is a free, open source, lightweight and fast desktop environment for Linux and BSD distributions. It comes with a number of great and well known features, which borrowed from LXDE desktop such as low system resource utilization, elegant and clean user interfaces. Additionally, one of its distinguished properties is the high level of customization to meet desktop usability needs.

Note: LXDE has been the the default desktop environment on Knoppiz, Lubuntu and a few other less known Linux distributions, however, LXQt is now the latest version of LXDE desktop and it is expected to ship by default on the above mentioned distributions.

#### LXQt Desktop Features ####

Below are a few of its significant components and additional features:

1.  pcmanfm-qt file manager, a Qt port for PCManFM and libfm
2.  lxterminal, a terminal emulator
3.  lxsession session manager
4.  lxqt-runner, a quick application launcher
5.  Ships in with an integrated energy-saving component
6.  Supports several international languages
7.  Supports several keyboard shortcuts together with many other minor features

The latest version of this relatively new desktop environment is LXQt 0.10, which has come with more than 400 bug fixes and a number of improvements as listed below:

1.  Solid replaces liblxqt-mount
2.  Custom power management code
3.  libscreen also replaces system xranr call and many more

### How To Install LXQt Desktop on Ubuntu ###

$ sudo apt-get update

# [How to Install LXQt 0.9.0 Desktop Environment in Ubuntu][] #

March 12, 2015 |  By [Arun Pyasi][]

Hi everyone, in this tutorial we'll learn about how to install the latest LXQT 0.9.0 Desktop Environment in Ubuntu Operating System and its derivatives like Linux Mint, Elementary OS, and many more. This article also includes some introduction and changelog of the latest LXQT Release.

LXQt is the Qt port and the upcoming version of [LXDE][], the Lightweight Desktop Environment. It is the product of the merge between the LXDE-Qt and the Razor-qt projects: A lightweight, modular, blazing-fast and user-friendly desktop environment.

LXQt 0.9 also brings in our first KDE Frameworks dependencies. KWindowSystem is a true-and-tested library for handling window events. It replaces our custom XFitMan library and will greatly help in becoming fully compatible with Wayland. KGuiAddons also replaces a hard dependency on Xlib in lxqt-panel.

## Changelog ##

### Theme changes ###

*  New theme: "Frost". A cold, dark theme courtesy of Inti Alonso. Screenshots available on lxqt.org!
 *  A-Mego, Flat and Green have been deleted as they were low quality or too similar to other themes.
 *  The old Dark theme has been merged with the Flat Dark theme from LXQt 0.8.

**Please note that theme re-configuration will be needed if you are using one of the old themes.**

### Component changes ###

*  The functionality of the old lxqt-power has been restored into an "lxqt-leave" component. It is now part of lxqt-session.
 *  Panel background is now configurable
 *  The main menu plugin can now be navigated using the keyboard
 *  The Clock plugin has been merged into the World Clock plugin. It has received several changes and no longer requires ICU. Reconfiguring the clock may be required upon upgrading depending on your settings.
 *  The power management component now supports displaying multiple batteries

### Other Changes includes ###

*  KWindowSystem replaces XfitMan in lxqt-panel, lxqt-runner, lxqt-session, lxqt-notificationd and lxqt-session.
 *  KGuiAddons replaces a hard dependency on Xlib in lxqt-panel
 *  A copy of xdg-utils is no longer bundled with LXQt. The minimum xdg-utils version required is 2012-03-02.

Here are the steps below by which we can install LXQT 0.9.0 on our Ubuntu Operating System. Here, I am running 14.0.4  LTS "Trusty" and this article should work fine in the previous releases of Ubuntu too.

## 1. Adding PPA Repository ##

One of the way to install LXQT in Ubuntu is by installing it using the PPA Repository. So, we'll need to add PPA Repository, to do so, we can simply fire the command below in a shell or a terminal:

>     $ sudo add-apt-repository -y ppa:lubuntu-dev/lubuntu-daily

## [![Adding lxqt PPA][]][Adding lxqt PPA] ##

## 2. Updating ##

Now, after we have added PPA Repository, we'll need to update the local repository source index of our Ubuntu machine. To update the source index, we'll need to run the following command:

>     $ sudo apt-get update

## [![Updating Source Index][]][Updating Source Index] ##

## 3. Installing LXQT ##

Now finally, we'll gonna install our best Lightweight LXQT Desktop Environment in our Ubuntu. To install it, we'll need to install the packages by running the command as shown below.

>     $ sudo apt-get install lxqt-metapackage lxqt-panel openbox

[![installing lxqt][]][installing lxqt]

After pressing Y and hitting enter, the installation will begin. At the end of installing the packages, we may be asked to choose a default window manager as shown below. Please select the window manager you like to set as default.

## 4. Running LXQT Desktop ##

After finishing the installation of LXQT, we surely want to give a test drive and run LXQT Desktop. To do so, we'll need to logout from the current desktop environment and then switch to LXQT Desktop.

So, after logging out, we'll get to see the options to select the desktop session as show in the below image.

So, after logging in with the required password, we'll get to see that our favorite Lightweight Desktop Enviornment will run and we'll get the desktop interface as shown in the following image.
