A Simple Path for Installing LXQt-desktop
in Ubuntu- and Arch-based Distributions


LXQt desktop, since early 2017, has been an excellent desktop environment, thought to be suitable even for not-very-powerful laptop or desktop computers. At the other end of the spectrum, I installed it on an upper-end gaming computer and was able to run glxspheres64 at an impressive > 2000 fps. Below is a simple, step-by-step recipe for installing LXQt Desktop in both Ubuntu- and Arch-based distributions.

1) Install a distribution suitable for a low-resource computer. I successfully have installed the LXQt desktop following the directions on this page in the Ubuntu-based distributions Lubuntu-16.10, 17.04, and 17.10*, and LXLE-16.04.1, as well as in Lubuntu's long-term-release distribution, 16.04.1. I also have successfully installed it in the Arch-based distribution Antergos-17.1 minimal distribution.

2) Download et_install_lxqt_desk from our bash script download page. "chmod 755" the file so it is executable. Then, from a command line, change to the directory in which et_install_lxqt_desk resides and issue the command "./et_install_lxqt_desk".   et_install_lxqt should work for most Ubuntu- and Arch-based distributions. Additionally, most non-newbies should be able to modify et_install_lxqt_desk to work with quite a few other distributions using the information provided here.

In early 2017, most versions of xdg-utils did not recognize the LXQt desktop and therefore did not work well with it. You may install our rewrite of xdg-utils-1.1.1, which does work well with the LXQt desktop, by downloading the bash script, et_install_xdg-utils from our script download page referenced above, which currently installs xdg-utils-1.1.1-et.

Finally, although LXQt seems to work fine with lightdm display manager in Lubuntu-17.10, in general it has the fewest problems when the sddm display manager is used. You can install and enable sddm yourself, or newbies can use our very simple et_install_sddm bash script.

Alternatively, you could do all these in one step by dowloading and executing our et_install_lxqt_all bash script.

Remember. It will likely be necessary to issue the command "chmod 755 SCRIPT" where SCRIPT is the name of the script, before being able to execute it.

*If you install LXQt desktop in Lubuntu-17.10 with the linux-4.13.0-16-generic kernel, you will not achieve anything approaching the 2400fps glxsheres64 speeds until Lubuntu removes the bug that prevents the nvidia-384 dkms modules from being inserted into the linux-4.13.0-16-generic kernel. Things worked fine before the upgrade from 4.13.0-15 kernel.
