Hello Linux Geeksters. As you may know, the LXDE developers have started porting their desktop environment to Qt, under the name of LXQt. 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.
Recently, a Lubuntu image using LXQt as default has been released, to allow the users to test the new desktop environment.
Or, you can install LXQt on your Ubuntu 14.10 Utopic Unicorn, Ubuntu 14.04 Trusty Tahr or derivative systems, like: Linux Mint 17 Qiana, Pinguy OS 14.04, Elementary OS 0.3 Freya, Deepin 2014, Peppermint Five, LXLE 14.04, Linux Lite 2.0 and other Ubuntu derivative systems.
To install and test LXQt 0.8 on your Ubuntu 14.10 Utopic Unicorn, Ubuntu 14.04 Trusty Tahr 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-session lxsession
Optional, to remove LXQt 0.8, do:
$ sudo apt-get remove lxqt-metapackage lxqt-session lxsession
$ sudo apt-get autoremove
