Hello Linux Geeksters. As you may know, LXQt (LXDE-Qt) is a lightweight desktop environment, unifying both LXDE and Razor-Qt. It uses PCManFM-Qt, a version of PCManFM, re-written in Qt, as the default file manager and Openbox as window manager and has support for Wayland, a new display server developed by Red Hat.
The latest version available is LXQt 0.9, which has been recently released. Among others, the Qt4 compatibility has been dropped, Qt 5.3 or newer being required, it now has KDE Frameworks dependencies, the window events are handled by kWindowSystem and Xlib has been replaced with KFuiAddons.
Also, a new dark theme has been added, having configurable panel background support, clock plug-in improvements and keyboard navigation for the main menu.
In this article I will show you how to install LXQt 0.9 on Ubuntu 15.04 Vivid Vervet, Ubuntu 14.10 Utopic Unicorn, Ubuntu 14.04 Trusty Tahr and derivative systems.
To install and test LXQt 0.9 on your Ubuntu 15.04, Ubuntu 14.10, Ubuntu 14.04 and derivative systems, all you have to do is add the needed ppas to your system, upgrade the package and install the lxqt-metapackage, lxqt-panel and openbox packages. Like this:
$ sudo add-apt-repository ppa:lubuntu-dev/lubuntu-daily
$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get install lxqt-metapackage lxqt-panel openbox
Optional, to remove LXQt 0.9, do:
$ sudo apt-get install ppa-purge
$ sudo ppa-purge ppa:lubuntu-dev/lubuntu-daily
$ sudo apt-get autoremove
