How To: Change Ubuntu Into Lubuntu

Today’s article is going to teach you how to change Ubuntu into Lubuntu. Why? Because you can! Because you might want to try a different desktop environment, or because you’d like to have them both on one computer. It’s remarkably easy to change Ubuntu into Lubuntu – and, of course, would work with other official Ubuntu flavors with just slight modifications

As you know, Ubuntu is a distro. Lubuntu is also Ubuntu, but it is an official flavor of Ubuntu. They are not actually different distros. Lubuntu is Ubuntu, with different Ubuntu software installed to provide a different experience.

Ubuntu is Canonical’s flagship operating system. It ships with a suite of useful software and uses the GNOME desktop environment. If you say Ubuntu, that’s the distro you’re talking about. Lubuntu is a separate project under the same umbrella, based on Ubuntu. Lubuntu, once known for being lightweight, is now using the LXQt desktop environment where it once used LXDE. The latter dropped for the former for a whole host of reasons, including maintenance improvements. Comparatively speaking, it’s still fairly lightweight.

Full Disclosure: I’m an “Official Lubuntu Member” and, by extension, also an Official Ubuntu Member. I’m quite biased with regards to Lubuntu, but my biases are open and I still strive to be objective (or at least not objectionable!).

So, if you have Ubuntu installed and you’d like to experience Lubuntu, then this is the article for you, as it will teach you how to …

Change Ubuntu Into Lubuntu:

Like oh so many articles, if you want to change Ubuntu into Lubuntu, you’re going to want to start off with an open terminal. You can use your menu to open a terminal, or you can just press CTRL + ALT + T and your default terminal should open.

Once you have your terminal open, you need to enter just one command, really. The command you’ll enter is:

That will run its course and then pause on a screen where you can read about your display manager. There are no real options on that page, so you can just press the enter button after reading it.

This won’t actually take all that long. When you’re done, you can logout and then login to Lubuntu or, more effectively, just reboot and you’ll boot into the Lubuntu environment. 

When you reach your new login menu, you can pick which desktop session you want to login with by using the dropdown menu in the upper left, with Lubuntu being the new default. Of course, you can login to the regular Ubuntu session still (as well as Ubuntu on Wayland). Most things will still work in when you’re logged into an Ubuntu session, except for blanking the screen. That fails because you’re no longer using GNOME-display-manager (GDM3). (You’re now using SDDM.)

That was it. That’s all you have to do. However, if you don’t like it and want to change it back, it’s slightly more complicated – but not terribly so – to reverse this change. To reverse it, you need to …

Change Lubuntu Into Ubuntu:

Once again, open your terminal. It’s not hard, as described in the 2nd section of this article. Heck, it’s described in almost every article.

You can start with just this command:

And that’ll get you almost all the way back to normal. You’ll still have the splash screen and boot logos that belong to Lubuntu. You could leave those and learn to accept them, or you can fully restore the original setup.

Assuming you want things back the way they were, we need to get your display manager reconfigured – restored to what it was. That’s a very easy command. It looks like:

You’ll get another one of those warning screens and, once again, there are no options. The only thing you can do is press the enter button. Fortunately, that’s exactly the button you want to press!

Finally, you need to change the boot screens. It’s a pretty easy command, but it is interactive. Just run this to get it started:

That will ask you which theme you want to use. In this case, you’ll pick 1 and press the enter key. Basically, you want the option that isn’t “Lubuntu” and this will fix the final visual issue.

When you next reboot, you’ll have the default Ubuntu logo and theme during the whole boot process (assuming everything went as expected). Your login theme will have been restored to Ubuntu’s default, as will have the Ubuntu splash screen while the system boots.

Of course, you could always opt to keep Lubuntu installed alongside Ubuntu, that is LXQt alongside Gnome, if you’d prefer. Then again, if you like your Lubuntu installation, maybe you’ll just want to use it. It’s easy enough to remove GNOME or to even just clean install Lubuntu.

Closure:

And there it is! It’s an article that teaches you how to change Ubuntu into Lubuntu. It’s not a very complicated affair and you can restore it easily enough, should you not like it. You can more or less do this with any other official flavor. Swapping back to just the old Ubuntu will potentially use different commands, but it’ll otherwise be quite similar.

How To: Determine Your Desktop Environment

Today’s article will help you determine your desktop environment. Often abbreviated as “DE”, your desktop can be any number of choices – including none at all. This should be a relatively short and easy article. If you don’t know, the desktop environment is a bunch of software that provides the GUI system you use to navigate, load files, and manage your computer.

Once in a while, an article should get back to the basics. This is one of those articles. When someone poses a question and you need to know their desktop environment, you can just tell them that you need that information and link to an article like this one.

As such, it’s not exhaustive nor is it expected to be all that deep. There are a number of ways to get your desktop information. For a more universal approach, these ways will all be through the terminal. In most other situations, you can use the GUI and figure it out. For example, you might use HardInfo and get the data that way. Not everyone will have that installed, so we can just do it though the terminal.

Determine Your Desktop Environment:

This article requires an open terminal, like many other articles on this site. If you don’t know how to open the terminal, you can do so with your keyboard – just press CTRL + ALT + T and your default terminal should open.

Now that you have your terminal open, you can try either ‘neofetch‘ or ‘screenfetch‘. Both of them will happily spit out the information you need. The screenfetch may be better here, as it also gives the version of your desktop environment – from what I can tell. Both are easy to install and may already be installed.

Here’s an example of the relevant output from running screenfetch in the terminal:

screenfetch displaying desktop environment information
See? It’s right there! Easy enough!

You can also do the same thing with running neofetch in your terminal. Once again, it looks something like this:

neofetch showing desktop environment
Once again, it’s nice and easy! Tada!

Now, there’s some chance you just want to determine your desktop environment and don’t need or want any additional information. You can do that. It’s not hard, it’s not hard at all. In fact, both are environment variables that you can easily get to echo as stdout.

You can also use:

Both of those will tell you the desktop environment that you’re using. See:

using echo to view the desktop environment
See? You can use either one effectively and efficiently.

As suggested by @wizardfromoz, of Linux.org fame, I completely forgot to include my beloved inxi. The inxi system information tool is increasingly installed by default, but the link will show you how to install it. It’s a great tool, providing a ton of information, that’s used frequently for support questions.

To use inxi to determine your desktop environment, you can just run:

That’s an uppercase S and it’ll look something like this:

inxi showing the desktop environment
See? It’s even included in the inxi output! inxi does it all!

And there you have it, a few different ways to determine your desktop environment from the terminal. You should probably just know this information, but newer users may not know and may need help in finding this information. 

Closure:

So, there’s another one… Yet another article, said and done. This one is pretty easy and aimed at rank beginners, but it’s not without use. It may even save some time as people might actually search before asking questions! Well, they could…
