Lubuntu 22.04.4 LTS is Released!

Thanks to all the hard work from our contributors, Lubuntu 22.04.4 LTS has been released. With the codename Jammy Jellyfish, Lubuntu 22.04 is the 22nd release of Lubuntu, the eighth release of Lubuntu with LXQt as the default desktop environment.

Support lifespan

Lubuntu 22.04 LTS will be supported for 3 years until April 2025. Our main focus will be on this and future releases.

What’s The Difference Between Lubuntu 22.04 LTS And This Release?

Lubuntu 22.04.4 is a set of images produced for convenience so that a fresh install of the latest Lubuntu LTS does not require as many updates after install. If you do system updates regularly, you are already running Lubuntu 22.04.4 LTS, and if you install Lubuntu on a system using a Lubuntu 22.04 LTS image and do system updates, that system will also then be running Lubuntu 22.04.4 LTS.

This Lubuntu 22.04.4 media also contains the updated HWE 6.5 kernel stack (from Lubuntu 23.10). This enables newer hardware to function more smoothly. Prior 22.04 22.04 media contained only the 5.15 GA kernel stack or now-outdated HWE kernel stacks.

What is Lubuntu?

Lubuntu is an official Ubuntu flavor which uses the LXQt desktop environment. The project’s goal is to provide a lightweight yet functional Linux distribution based on a rock-solid Ubuntu base. Lubuntu provides a simple, modern and powerful graphical user interface, and comes with a wide variety of applications so you can browse, email, chat, play, and be productive.

You can find the following major applications and toolkits installed by default in this release:

  • LXQt 0.17.0 – more information here.
  • Qt 5.15.3
  • Mozilla Firefox will be shipped as a Snap package with version 122 and will receive updates throughout the support cycle of the release.
  • The LibreOffice 7.3.7 suite.
  • VLC 3.0.16, for viewing media and listening to music.
  • Featherpad 1.0.1, for notes and code editing.
  • Discover Software Center 5.24.7, for an easy, graphical way to install and update software.

You can find a variety of other applications installed which aim to enhance your experience while staying out of the way of your normal workflow.

Please note: The change of firefox to snap package, results in the browser being slower to start. It does not impact execution or subsequent runs during that session. The reason for this is because setting up the confined environment in which snaps run takes time. This is noticeable on first run especially with live media having improved significantly when compared to prior Lubuntu 22.04 LTS media. The confined environment provides significant security and privacy benefits.

If you’d like to use LXQt 1.4 on your existing, or new Lubuntu 22.04.4 LTS install, then please see how to upgrade it with the use of the Lubuntu Backports PPA.

Upgrading Lubuntu to 22.04 LTS

Notice about upgrading from Lubuntu 20.04 LTS with LXQt

If you are upgrading from Lubuntu 20.04 LTS that has LXQt, this new version uses a different Openbox settings configuration file. If you have customized ~/.config/openbox/lxqt-rc.xml you will want to copy that file to ~/.config/openbox/rc.xml. New installations are not impacted by this change.

New installs of Lubuntu 22.04 LTS no longer include the programs trojita, fcitx and k3b, which will cause those applications to be removed from your existing system on upgrade, unless you mark them as manually installed using the procedure we’ve documented here. You should do this for each of the programs you use, before you perform the upgrade.

For more information about upgrading please visit our manual page that describes the process. In addition, more information about upgrading releases in Ubuntu and all the flavors for the 22.04 release, can be found here.

Where can I download it?

You can download Lubuntu 22.04.4 LTS on our downloads page.

Installer

Lubuntu uses the Calamares system installer in place of the Ubiquity installer that most other flavors use. 22.04 ships with Calamares 3.2.61. For a full/erase disk install, we have added the option of a swapfile by default. The swapfile size is initially set to 512 MB. The option for no swap is still available as a dropdown selection.

For a full description of the new features and fixes, see the upstream announcements for 3.2.61.

Lubuntu Manual

The Lubuntu Team has been hard at work in polishing the Lubuntu Manual to make it easy for new and experienced users alike to use their system more productively. The book can be found at manual.lubuntu.me.

We want to thank Lyn Perrine for all the hard work she has put into the Lubuntu Manual. Thank you!

All existing URLs now redirect to https://manual.lubuntu.me/stable/. Going forward, the tip of the master branch (WIP documentation for the next release) can be found at https://manual.lubuntu.me/master/, and documentation for Lubuntu 22.04 LTS can be found at https://manual.lubuntu.me/lts/. While the documentation for previous releases will be kept in the Git repository, they will not be published anywhere.

Contributors

We would like to thank the following contributors for dedicating their time to Lubuntu this cycle. Thank you!

In addition, we would also like to recognize some very active contributors on our Discourse forum.

Thank you for contributing to the Lubuntu community!

Global Team

The Lubuntu Global Team has been created to foster communities in non-English languages and locales, and includes Hans Möller, Noumeno, and Jyoti Gomes as the initial drivers of the project. An up-to-date list can be found on our Links page, but the existing groups include: Spanish, Portuguese, Russian, Italian, Chinese, German, Japanese, Arabic, and French. If you would like to start a language group, join our development channel and talk with the Global Team. At minimum, you should have a few interested drivers of the community, and at least one administrator that speaks English.

We now have multiple languages available in the support section of our Discourse forum.

Resolved Bugs

The original Lubuntu 22.04 LTS media when used to install with a btrfs file-system usually resulted in an unbootable system due to this bug. This did not affect upgraded systems, impacting only new installs using BTRFS file-systems and 22.04 media; this issue will not impact new installs of Lubuntu 22.04.4 LTS.

The lubuntu-update-notifier did not prompt users when configuration files conflicted with installed versions. In addition, if lubuntu-update-notifier was interrupted during an upgrade there was no mechanism to handle that. Further information can be found on our Discourse post.

Libreoffice online help was previously not usable due to a confinement issue with the firefox snap, snapd, and this issue. This has now been resolved.

Known Bugs

Please check the Ubuntu Release Notes for more common issues and bugs affecting all Ubuntu flavors.

Lubuntu 23.04 Reaches End-of-Life – Upgrade to 23.10 Now

Lubuntu 23.04 has reached end-of-life as of today, January 25, 2024. It will no longer receive software updates (including security fixes) or technical support. All users are urged to upgrade to Lubuntu 23.10 as soon as possible to stay secure. You can upgrade to Lubuntu 23.10 without reinstalling Lubuntu from scratch by following the official upgrade procedure. Alternatively, you can download Lubuntu 23.10 or Lubuntu 22.04 and do a clean installation if you prefer.

Nine months ago, on April 20th, 2023, Lubuntu 23.04 was released. It shipped a number of new features including an enabled-by-default X compositor (Picom), PipeWire, a new default screensaver, and the latest (at the time) version of LXQt. While the innovation and stability Lubuntu 23.04 provided served us well, it is now time to move on. We are now focusing our support efforts on Lubuntu 23.10 and later, as well as on Lubuntu 22.04 LTS. Lubuntu 23.04 will no longer receive bug or security fixes from the Lubuntu team. Additionally, as the underlying Ubuntu 23.04 packages Lubuntu uses have reached end-of-life, Lubuntu 23.04 will no longer receive updates for any core applications, utilities, or OS components.

Lubuntu features two different types of releases – Long Term Support (LTS) releases and interim releases. Interim releases are supported for only nine months after release, and are primarily for users who are willing or able to upgrade or reinstall frequently in order to get the best that Lubuntu has to offer. Lubuntu 23.04 was an interim release, and is being dropped from Lubuntu support accordingly.

Note that users of Lubuntu 22.04 LTS do not have to take any action at this time. LTS releases are supported for three years from the date of release. We will continue to support Lubuntu 22.04 LTS until April 2025.

If you are still running Lubuntu 23.04, we strongly recommend that you upgrade to Lubuntu 23.10 as soon as possible. You can read about what’s new in Lubuntu 23.10 here. Alternatively, if you are unable to use Lubuntu 23.10, or if you would like to use our LTS releases and avoid frequent upgrades, you can install Lubuntu 22.04 from scratch and enjoy another year of updates and support before having to upgrade again.

Thank you to everyone who uses Lubuntu! If you have problems reinstalling or upgrading, feel free to ask for help via our official support channels. We’re happy to help users having upgrade problems even after Lubuntu 23.04’s end-of-life date. You can find a list of places to reach us by visiting our Links page. We can also be reached via IRC at #lubuntu on Libera.Chat.

Noble Numbat: The Next Generation of Lubuntu

The Lubuntu Team has been hard at work already this development cycle polishing the Lubuntu desktop in time for our upcoming Long-Term Support release, 24.04 (codenamed Noble Numbat). We have pioneered groundbreaking features and achieved remarkable stability in crucial components. These enhancements are not just technical milestones; they're transformative changes you'll experience when you install the next version of Lubuntu.

To get the latest Lubuntu developments at your fingertips, follow us on X or Mastodon.

Without further ado, we are excited to announce the Lubuntu 24.04 LTS Alpha featureset.

Lubuntu's Installer

Why We're Sticking With Calamares

One common query we often encounter is: Why does Lubuntu use Calamares? This question is best understood with a bit of historical perspective, which we hope will bring clarity on the decisions and developments that led to our current choice.

In the turbulent 18.10 cycle, Lubuntu swiftly transitioned from LXDE to LXQt, shifting our primary desktop environment. With this change, we've moved away from supporting LXDE and, consequently, from a primarily GTK-based application stack. The rationale is simple: a desktop environment that uniformly utilizes either Qt-based or GTK-based applications is more resource-efficient than one combining both.

During this process, we discovered that Ubiquity, Ubuntu's existing desktop installer, has two frontends: a KDE frontend, and a GTK frontend. The KDE frontend was obviously written with KDE in mind, and contained a significant amount of technical debt. Resolving this technical debt (given that the Ubuntu Installer Team only put(s) active effort towards the GTK frontend) would have pushed our transition to LXQt out further, which would have resulted in increased instability for 20.04 LTS.

Instead of taking this route, we decided to do what no other flavor had done before us: use Calamares. To this day, Calamares is exponentially faster than Ubiquity, both in progressing through the pages and doing the install itself. We have received requests for items such as a Minimal Install option in Calamares, and other options specific to Ubiquity. We have jumped over many hurdles this cycle, and we are proud to say that Calamares is essentially at feature-parity with Ubiquity.

The Ubuntu Desktop Team has recently been working on the new Ubuntu Desktop Installer. This tool, developed with Flutter and distributed as a snap, is intended to provide a frontend interface for Subiquity, which is the new installer for Ubuntu Server. They are attempting to replace Ubiquity, which is a noble mission.

After thorough evaluation of the new installer, the decision was made not to adopt it for our use. We found that Calamares consistently and continously outperforms the new installer in UI page performance and installation speed, and aligns more closely with our existing theming. Furthermore, the requirement for each flavor to create a separate snap for theming purposes presents a less than optimal solution. Excluding one specific application, our stance is in favor of using Qt applications over Flutter applications.

Other flavors are more than welcome to adopt Calamares. After all, it is already used by quite a few other distributions, and we would be happy to help.

What's new this cycle?

Lubuntu's installer now has a Customize menu:

From the Lubuntu installer, you can now select one of three options:

  • Minimal Installation: barebones install without snapd
  • Normal Installation: regular application set, what you already know and love
  • Full Installation: the Normal Installation, but with Element, Thunderbird, Krita, and Virtual Machine Manager installed.

In terms of the checkboxes, Ubiquity has tricky wording. You may notice it is almost identical: the difference is, this checkbox both downloads and installs updates at the end. If you are installing with a reliable Internet connection, this is always recommended.

The third-party software is what you would expect: the restricted extras addons.

We also have a new desktop icon for Calamares:

And we've done some work to clean up theming, which will be landing over the next week or so.

Installer Prompt

Lubuntu's Try or Install feature has been missing since 18.04, but now it's back!

Introducing the Lubuntu ISO's "First Boot" screen:

When you select a Wi-Fi network (the list automatically updates if you're walking around!) and click Connect, you will be prompted for your password:

If your password is too short or too long, it will not let you Connect. If you get the password wrong, it will let you retry.

Also, when selecting your language and clicking Confirm, the language both on your live session and your installed session will be set appropriately.

Ubuntu Desktop does not currently have this feature.

If you have an Internet connection, or if your language is one of the top five in the world, this will also download GNOME, KDE, and LibreOffice language packs. A non-native English speaker should never have to read English to use Lubuntu, that's our goal. It doesn't add much disk space either (less than 20 MB per language.)

Bluetooth Management

We have lacked a GUI for Bluetooth in Lubuntu for a long time. This is now fixed. If you search for "Bluetooth Manager" in the LXQt menu, you can now seamlessly configure your bluetooth devices:

The only downside to this is, it's GTK-based. Before the release of 26.04 LTS, we plan to rewrite this in Qt with full feature parity.

SDDM Configuration Editor

Want a way to configure the login screen on Lubuntu, but don't want to configure it the hard way? Try SDDM Configuration Editor from the LXQt menu:

You can change your theme, preview a new one, and even change your default session!

Redshift: Dim the screen at night

By launching Redshift from the menu, a blue light filter activates, making the screen easier to view at night. There is no graphical way to configure it yet, but there is a right-click menu in the panel for temporarily suspending it:

Lubuntu Manual Icon

We've refreshed the icon for the Lubuntu Manual:

New (Optional) Themes

We recently announced several new themes available in Lubuntu by default:

A Windows Eleven-inspired theme

And sombre-et-rond, a modern dark theme for LXQt:

All images come directly from the upstream author.

We are looking for more themes to include as options. If you find any, or know of any themes we should get rid of, please let us know.

Power Management UX (Work in Progress)

We are simplifying and refining the user experience around these messages:

Our end goal is to only provide the information that is actually useful. If you start a virtual machine, it should not warn you about not having a battery.

Updated Battery Icon

Instead of the default icon having little precision about the battery percentage (low/medium/high), we changed it to indicate the percentage at all times.

24.10 and Beyond: Wayland and Qt 6

Our goal is to completely switch Lubuntu to Wayland and Qt 6 by the release of 24.10. This may seem like a large task, but LXQt has been working on Wayland support upstream for some time now, and the porting process from Qt 5 to Qt 6 is designed to be incredibly simple. That being said, you can expect 24.10 to be slightly rough around the edges. We expect these transitions to be fairly seamless compared to past ones, with the end goal being complete feature parity, but there are always unknowns when making significant shifts like this. It will be swift, and early 24.10 Alpha ISOs may be unusable.

Wayland has been default in Ubuntu Desktop since 22.04 for most systems, and Red Hat will be removing support for X11 entirely in its next release. That being said, unless the Ubuntu Archive Administrators move to remove X11 entirely before this point, we will be supporting the X session as an opt-in choice through 26.04 LTS, at minimum. At this point, we will evaluate any remaining issues, and make a followup decision.

We have one primary objective to meet before 26.04 LTS: make it so seamless that the user does not have to worry about it. This may mean providing an optional Wayland session for 24.04 LTS, just to "get the ball rolling," but we are unsure exactly what this looks like yet. It will be optional for 24.04 LTS but default for 24.10.

But wait, there's more…

There are several other features we are working to include in time for this release; that being said, it is a Long-Term Support release, so we will only be shipping features we are sure we can support. If you would like to make a suggestion, please join us.

We can always use more help! No matter your skill level or your technical experience, there’s something you can help with that can make a huge difference in Lubuntu. Whether you know another language, have some spare time to help us test Lubuntu, are good at writing documentation, or just want to stay “in the know,” get involved!

If you want to contribute to Lubuntu but do not feel you have the time or skills, consider donating to Lubuntu. Another great method to get involved is bug reporting. If you notice an issue, please file a bug. Don’t want to file a bug? Let us know what the problem is (in detail, enough that we can reproduce it) and we can assist you in filing one or do it ourselves.

Lubuntu 23.10 Backports PPA Released with LXQt 1.4

When users first download Lubuntu, they are presented with two options:

  • Install the latest Long-Term Support release, providing them with a rock-solid and stable base (we assume most users choose this option).
  • Install the latest interim release, providing the latest base with the latest LXQt release.

As we have mentioned in previous announcements, Kubuntu and KDE Neon created the idea of a "Backports PPA." This PPA (or repository, in the case of KDE Neon), exists to layer stable feature updates on top of the rock-solid Ubuntu core you know and love. We were inspired by this idea, and decided to create the Lubuntu Backports repository.

Our intention has originally only been to release these updates for Long-Term Support users. However, we have received an overwhelming amount of feedback from users and corporate partners alike, asking us to release these updates for 23.10. Therefore, we are making an exception by creating this additional repository.


This provides a fourth option for users: install 23.10, enable Backports, and get the latest-and-greatest LXQt, without exposing yourself to the churn of a usual development release cycle (which you can also download, if you'd like to help us out) and its instability. That being said, 23.10's Backports are much less tested. Proceed with appropriate caution.

You can enable this repository via the command line, using the following command:

$ sudo add-apt-repository ppa:lubuntu-dev/backports-mantic

Then, you can run Apply Full Upgrade from the LXQt menu. (It will take us a few days to get everything fully migrated over, so be patient if you don't immediately receive these updates.)


PLEASE NOTE: After 24.04 LTS is released, this PPA will be DELETED. It WILL cause apt error messages, halting the process before completion, when you update your system after that point. Please, upgrade to 24.04 LTS when it's released in April 2024, so you do not experience these issues. Also, this PPA is NOT compatible with the 22.04 Backports PPA. Upgrades from 22.04 LTS Backports to 23.10 in general are NOT supported, that does not change with this PPA.

It's a bad idea to enable the Staging repositories if you come across them. Just don't do it, unless you're planning on helping.

LXQt 1.4, Arriving at a Lubuntu Backports PPA Near You

The Lubuntu Team is happy to announce that the Lubuntu Backports PPA with LXQt 1.4 is now available for general use. You can find details on enabling it below.

What is the Lubuntu Backports PPA?

Our Backports PPA is modeled after Kubuntu's. It exists to provide the latest LXQt desktop stack on top of a stable Ubuntu base. (The concept could also be considered similar to KDE Neon.) As time goes on, our development focus will continue to be on new releases, and we plan on landing and testing changes there prior to pushing them to Backports. That being said, this is a perfect middle ground between stability and new features that users of all experience levels will be able to enjoy.

What's new in this release of LXQt?

LXQt About in 1.4


lxqt-menu-data has been created to handle menu files across LXQt. You may experience some slight changes in menu functionality:

Updated menu in LXQt 1.4


Updated file manager settings in LXQt 1.4

You can now specify the terminal to use when selecting Open In Terminal from the context menu.


New Audible Bell option in QTerminal

At last, QTerminal supports an audible bell. We've left this disabled by default, for the time being.


Preliminary support has been added for color profiles in LXImage (Qt).


Many other bugfixes and small changes have been included. Let us know if you run into any issues. More information on this LXQt release can be found here, and on the LXQt website.

Is this a separate edition of Lubuntu?

Nope, this is still the same Lubuntu you know and love, you're just getting new features available on the regular releases earlier than everyone else on the LTS release. You're jumping on an in-between track.

Okay, so how do I enable it?

The Backports PPA is available here. You can add the PPA using the following command: $ sudo add-apt-repository ppa:lubuntu-dev/backports Please note that upgrades from 22.04 to an interim release are NOT supported once Backports is enabled. Please let us know if anything is off.

You, yes you, can help

If you have some time, please consider joining us. If you would like to help us continue the development of the project long-term, you can donate to the Lubuntu project here.

Lubuntu 23.10 Released!

Thanks to all the hard work from our contributors, Lubuntu 23.10 has been released. With the codename Mantic Minotaur, Lubuntu 23.10 is the 25th release of Lubuntu, the 11th release of Lubuntu with LXQt as the default desktop environment.

Support lifespan

With Lubuntu 23.10 being an interim release, it will follow the standard non-LTS support period of nine months; this means that Lubuntu 23.10 will be supported until July 2024. Our development focus going forward will be on Lubuntu 24.04 LTS and future releases, so only critical bugfixes and security updates will be provided.

If you choose to use Lubuntu 23.10, we STRONGLY recommend upgrading to 24.04 LTS soon after it is released, but before Lubuntu 23.10 hits end of life. If this is not suitable for you, but you still enjoy new features on a regular basis, we would recommend staying on Lubuntu 22.04 LTS with Lubuntu’s Backports enabled.

We are in the process of landing updates to Lubuntu Update Notifier for all currently-supported stable releases to add a graphical path to version upgrades.

Installation

You can download Lubuntu 23.10 here. If you would like to upgrade your existing 23.04 installation, please visit our manual page describing the process. Common Ubuntu instructions can be found here.

Known Issues and Notable Changes

System Installer

We are once again utilizing Calamares 3.3 Alpha 2 in Lubuntu 23.10, as it has proven to be highly reliable since its initial use in Lubuntu 22.10.

During testing, we did note that if you attempt to create an encrypted installation without a passphrase, Lubuntu will be installed unencrypted. This is unlikely to be a problem for most users as disk encryption requires a passphrase for it to be effective. More information can be found here.

Artwork

We have a new wallpaper (which is also used as at the login screen), created one of our Lubuntu Members; Walter Lapchynski, with a bit of assistance from Ubuntu Studio’s Erich Eickmeyer. Thanks to both Walter and Erich.

Lubuntu 22.04.3 LTS is Released!

Thanks to all the hard work from our contributors, Lubuntu 22.04.3 LTS has been released. With the codename Jammy Jellyfish, Lubuntu 22.04 is the 22nd release of Lubuntu, the eighth release of Lubuntu with LXQt as the default desktop environment.

Support lifespan

Lubuntu 22.04 LTS will be supported for 3 years until April 2025. Our main focus will be on this and future releases.

What’s The Difference Between Lubuntu 22.04 LTS And This Release?

Lubuntu 22.04.3 is a set of images produced for convenience so that a fresh install of the latest Lubuntu LTS does not require as many updates after install (as Lubuntu continues to release Stable Release Updates and security fixes to make your experience as smooth as possible and to fix any bugs, if you want to help us out with this, see below, we always need more help). If you do system updates regularly, you are already running Lubuntu 22.04.3 LTS, and if you install Lubuntu on a system using a Lubuntu 22.04 LTS image and do system updates, that system will also then be running Lubuntu 22.04.3 LTS.

This Lubuntu 22.04.3 media also contains the updated HWE 6.2 kernel stack (from Lubuntu 23.04) where prior 22.04 media contained only the 5.15 GA kernel stack or 5.19 HWE kernel stack.

What is Lubuntu?

Lubuntu is an official Ubuntu flavor which uses the Lightweight Qt Desktop Environment (LXQt). The project’s goal is to provide a lightweight yet functional Linux distribution based on a rock-solid Ubuntu base. Lubuntu provides a simple but modern and powerful graphical user interface, and comes with a wide variety of applications so you can browse, email, chat, play, and be productive.

You can find the following major applications and toolkits installed by default in this release:

  • LXQt 0.17.0 – more information here.
  • Qt 5.15.3
  • Mozilla Firefox will be shipped as a Snap package with version 116 and will receive updates throughout the support cycle of the release.
  • The LibreOffice 7.3.7 suite.
  • VLC 3.0.16, for viewing media and listening to music.
  • Featherpad 1.0.1, for notes and code editing.
  • Discover Software Center 5.24.7, for an easy, graphical way to install and update software.

You can find a variety of other applications installed which aim to enhance your experience while staying out of the way of your normal workflow.

Please note: The change of firefox to snap package, results in the browser being slower to start. It does not impact execution or subsequent runs during that session. The reason for this is the setting up of the confined environment in which snaps run, and decompress the squashfs, with privacy and security benefits. This is noticeable on first run especially with live media having improved significantly when compared to prior Lubuntu 22.04 LTS media.

If you’d like to use LXQt 1.2 on your existing, or new Lubuntu 22.04.2 LTS install, then please see how to upgrade it with the use of the Lubuntu Backports PPA link here.

Lubuntu 20.04 LTS End of Life and Current Support Statuses

Lubuntu 20.04 (Focal Fossa) was released April 23, 2020 and will reach End of Life on Friday, April 28, 2023. This means that after that date there will be no further security updates or bugfixes released for your Lubuntu packages. We highly recommend that you upgrade to Lubuntu 22.04 LTS as soon as possible if you are still running Lubuntu 20.04.

After April 28th, 2023, the only supported releases of Lubuntu will be 22.04 (until April 2025), 22.10 (until July 2023), and 23.04 (until Jan. 2024). All other releases of Lubuntu will be considered unsupported, and will no longer receive any further updates (or support) from the Lubuntu team.

You can find instructions on how to install or upgrade Lubuntu in our manual.

For further details please refer to our forum post.

Lubuntu 23.04 Released!

After months of clawing our way through development, testing, and bug fixing, the Lubuntu team is thrilled to shell-ebrate another successful release cycle! We’ve finally pinched a working copy of the Lubuntu operating system, and it’s our biggest catch yet: Lubuntu 23.04 Lunar Lobster, the 24th release of Lubuntu and the tenth to feature LXQt as its default desktop environment. So let’s all shell-ebrate with some Lunar Lobster puns!

Support lifespan

With 23.04 being an interim release, it will follow the standard non-LTS support period of nine months; this means that 23.04 will be supported until January 2024. Our development focus going forward will be on 23.10 and future releases, so only critical bugfixes and security updates will be provided. If you choose to use 23.04, we STRONGLY recommend upgrading to 23.10 once it is released, before 23.04 hits end of life. If this is not suitable for you, but you still enjoy new features on a regular basis, we would recommend staying on 22.04 LTS with Lubuntu’s Backports enabled.

You can download 23.04 here. If you would like to upgrade your existing 22.10 installation, please visit our manual page describing the process. Common Ubuntu instructions can be found here.

Known Issues and Notable Changes

LXQt

A bug in LXQt results in duplicate menu entries for the Calamares installer, showing the following:

While either of these options work, we recommend using the desktop icon.

While LXQt 1.3.0 has already been released at this time, it was released after Lubuntu 23.04’s Feature Freeze. As a result, Lubuntu 23.04 ships with LXQt 1.2.0 with 1.2.1 point releases updates for a few components. We intend to ship LXQt 1.3.0 or later with Lubuntu 23.10. LXQt 1.3.0 will also be backported to Lubuntu 22.04 LTS if possible.

System Installer

In Lubuntu 22.10, we chose to ship an (at the time) very recent alpha testing version of the Calamares installer, Calamares 3.3 Alpha 2. This worked quite well, and over the past several months Calamares 3.3 has been battle-tested by our developers, our testing team, and our users of Lubuntu 22.10, with no high-impact bugs discovered in Calamares itself. We have therefore chosen to continue shipping Calamares 3.3 Alpha 2 in Lubuntu 23.04.

During testing, we did note that if you attempt to create an encrypted installation without a passphrase, Lubuntu will be installed unencrypted. This is unlikely to be a problem for most users as disk encryption requires a passphrase for it to be effective. More information can be found here.

User password requirements

During testing, we discovered that it was possible to instruct Calamares to create the initial user account with a blank password. This was not the result of a bug in Calamares, but was rather due to incorrect configuration in Lubuntu. Due to the security implications of this, and because of a bug in XScreenSaver that could result in the user being locked out if the password is blank, we have chosen to require that some password be provided during the installation process, even if that password is only one character long. More details can be found in the official bug report.

If you fully understand what you are doing and do not want a password, there are several ways of disabling most or all password-based authentication in Lubuntu. These methods are documented on our Discourse forum here. We highly recommend that most users do not remove or otherwise disable their system’s password for security reasons.

PipeWire

Lubuntu previously used the PulseAudio audio system to provide rich audio functionality to our users. However, recently Ubuntu and its flavors have been gradually shifting to using the PipeWire audio server in place of PulseAudio. PipeWire offers several advantages over PulseAudio, including improved Bluetooth support, and more powerful management features for complex audio-related workloads. In order to offer these improved features to our users, Lubuntu has replaced the PulseAudio audio system with PipeWire in Lubuntu 23.04.

Screensaver

Since Lubuntu 20.04, the default screensaver has been “Flurry”. Due to reports of screensaver glitches on certain hardware, we have switched the default screensaver in Lubuntu to GL Matrix. This screensaver features a 3D “digital rain” effect that we have found to be aesthetically pleasing. If you have changed the screensaver yourself, you will probably not notice this change. If you find the new screensaver unappealing, you can change it back to the original “Flurry” screensaver (or to any of the other pre-installed screensavers) using the Screensaver application.

Picom

Lubuntu 22.10 and earlier run with no X compositor by default. (An X compositor is an application that can help provide various graphical effects and possibly smooth out screen tearing.) For those who benefited from X compositing, the Compton compositor was provided. We began also providing the Picom compositor (which is based on Compton but is more well-maintained) in Lubuntu 21.04. Starting with Lubuntu 23.04, we have switched entirely to Picom, and have enabled X compositing by default. This will allow effects like panel transparency to work out of the box rather than requiring that the compositor be manually enabled.

If you discover that X compositing is causing problems for you, or if you are experiencing significantly more screen tearing than in previous versions of Lubuntu, you can turn X compositing off by going to the Application Menu -> Preferences -> LXQt Settings -> Session Settings. You can then find and uncheck the “Picom (X compositor)” entry under “LXQt Modules”, and then click “Close”. X compositing should be disabled the next time you log in.

Artwork

We have refreshed the wallpaper, the default background for the login screen, the installer welcome image, and the installer slideshow for Lubuntu 23.04. This updated artwork was provided by one of our Lubuntu Members, Aaron Rainbolt.
