How To Install LXQt 0.9 On Ubuntu 15.04, Ubuntu 14.10, Ubuntu 14.04 And Derivative Systems

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.

For now, LXQt is used by default on Siduction, but it can be installed on Arch Linux, Fedora, OpenSUSE, Mageia and Manjaro.

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.
