How To Install LXQt 0.7.0 On Arch Linux

Hello Linux Geeksters. As you may know, the LXDE developers have started the porting of their LXDE desktop environment to Qt, the new project being called LXQt. While LXDE is based on GTK+2, the developers have decided to port LXDE on Qt5, instead of GTK+3. The latest version available is LXQt 0.7.0.

The LXDE developers have also posted an article giving RAM consumption numbers of XFCE, LXDE and LXQt, all this systems running on a virtual Debian Testing system with 512 MB of RAM and a single core processor:

  • XFCE: 89 MB (with default configuration of Debian. This value will increase after xfce is ported to gtk+ 3)
  • LXDE (gtk+ 2 version): 78 MB (add 20 MB to openbox)
  • LXQt: 95 MB (add 37 MB to openbox, still has some room for optimization)

While LXQt will not be used by default on Lubuntu 14.04 due to the fact that the porting process will not be ready until the release of the next Lubuntu system, the new desktop environment can be tested on Lubuntu 14.04 and Lubuntu 13.10. Also, if you want to test LXQt, you could try Siduction, a system based on Debian Unstable using LXQT as default.

In this article I will show you how to install LXQt 0.7.0 on Arch Linux systems.

Because it is available via some third party repository, installing LXQt on Arch Linux is easy. Follow the below instructions exactly, in order to get a successful installation.

Add the repository to your system:

$ sudo sh -c 'echo "[repolxqt]" >> /etc/pacman.conf'
$ sudo sh -c 'echo "SigLevel = Optional TrustAll" >> /etc/pacman.conf'
$ sudo sh -c 'echo "Server =$arch/repolxqt/" >> /etc/pacman.conf'

Next, you can either install LXQt and Openbox, as the default window manager:

$ sudo pacman -Sy lxqt-desktop-git openbox

Or, you can install PCManFM-Qt and qt-LXimage image:

$ sudo pacman -Sy pcmanfm-qt-git lximage-qt-git

Also, you can install SDDM and enable, a lightweight display manager for X11:

$ sudo pacman -S sddm-git
$ sudo systemctl enable sddm
