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


LXQt desktop in early 2017, is an excellent desktop environment, thought to be suitable even for not-very-powerful laptop or desktop computers. I have installed it on an upper-end gaming computer and am able to run glxspheres64 at an impressive > 2200 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 have successfully installed the LXQt desktop following the directions on this page in the Ubuntu-based distributions Lubuntu-16.10 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 from here. Rename the file back to et_install_lxqt if the name gets changed during the download, and "chmod 755" the file so it is executable. Then, from a command line in the appropriate directory, issue the command "./et_install_lxqt".   et_install_lxqt should work for most Ubuntu- and Arch-based distributions. Additionally, most non-newbies should be able to modify et_install_lxqt to work with quite a few other distributions using the information provided here.

That is all you have to do. The et_install_lxqt script actually does three things. First it installs the LXQt destop, then it offers to install xdg-utils-1.1.1-et, and finally it offers to switch you to the sddm display manager.

I recommend you do all three things. On Ubuntu-based systems, xdg-utils-1.1.1-lubuntu2, does not recognize the LXQt desktop. I suspect this applies to other distributions as well. To correct this deficiency, you should install my rewrite of xdg-utils-1.1.1, which seems to work well. Finally, I found several problems, on several distributions, using lightdm as the display manager with LXQt desktop, so I recommend switching to LXQt's recommended display manger, sddm.
