Welcome to the Lubuntu flavour wiki page

The objective of the Lubuntu project is to create a variant of Ubuntu that is lighter, less resource hungry and more energy-efficient by using lightweight applications and LXDE, The Lightweight X11 Desktop Environment, as its default GUI.

Lubuntu is targeted at PC and laptop users running on low-spec hardware that, in most cases, just don't have enough resources for all the bells and whistles of the "full-featured" mainstream distributions. Members of the team take care of LXDE and other packages that are part of Lubuntu. Lubuntu received official recognition as a formal member of the Ubuntu family, commencing with Lubuntu 11.10. Even though Lubuntu is a lightweight distribution, it does not mean you will not be able to run all applications that other distributions are currently offering. It does mean that it is prepared and developed for low-specification computers. Nonetheless, you can run any application available in the official repositories, as long as your hardware can bear with it.

Please join us and contribute to an exciting international Free and Open Source Software project. We look forward to working together with you.

The default "Desktop" installer requires 384-800 MB of RAM (depending on selected options.) If you have problems, please use the alternative installer.

Get Lubuntu

To download Lubuntu and see the various options available head over to Get Lubuntu. This section discusses both the standard installs and those required for computers with low memory (RAM), old chipsets (i586) and low disk-space (netbooks). Make sure to read the release notes!

Upgrading from last release

When upgrading, it is recommended that you back up your own data.

The update manager GUI will offer you the next release of Lubuntu (it shows as Ubuntu, but updates Lubuntu); Alternatively, launch LXTerminal and enter

sudo do-release-upgrade

Please NOTE: Upgrade details (along with all detail on this page) apply to legacy releases of Lubuntu using LXDE. Lubuntu switched to the newer LXQt desktop with Lubuntu 18.10 meaning the instruction here ended after upgrading to Lubuntu 18.04 LTS.

If you read later release notes (eg. https://lubuntu.me/focal-1-released/) you'll read

• "Note, due to the extensive changes required for the shift in desktop environments, the Lubuntu team does not support upgrading from 18.04 or below to any greater release. Doing so will result in a broken system. If you are on 18.04 or below and would like to upgrade, please do a fresh install."

Lubuntu vs Ubuntu

Both Lubuntu and Ubuntu share two major important things: same Core System and same Repositories. Lubuntu and Ubuntu belong to the same family and talking about each as totally different two systems is not correct since they have some things in common. Thus, we use the same Forum Area and share many Wiki Pages.

The differences between Lubuntu and Ubuntu are:

• Different DE - Lubuntu uses LXDE while Ubuntu uses Unity as the default DE on releases up to Lubuntu 18.04 LTS. Lubuntu uses LXQt from Lubuntu 18.10.

• Different Default Applications

Other than that, they are the same. The DE is what makes Lubuntu a lightweight OS, and of course the selected applications too because we make sure to use the lightest applications which are not resource hungry. However, you are still free to use any application available in Ubuntu’s repositories, as long as your computer can run it.

Lubuntu is recognized as a member the Ubuntu family by the developers of Ubuntu.

As of 14.04, long term support (LTS) versions are available.

Lubuntu vs Windows 7

For those of you who are feeling that your computer is not working anymore with Windows 7 because, say, it is getting slower, here is a chart comparing Lubuntu’s starting applications and the most used softwares in Windows 7:

IRC channels

Internet Relay Chat (IRC) is a form of real-time Internet chat. It is mainly designed for group (many-to-many) communication in discussion forums called channels, but also allows one-to-one communication via private message.

LXQt

LXQt is the Qt port and the upcoming version of LXDE, the Lightweight Desktop Environment. It is the product of the merge between the LXDE-Qt and the Razor-qt projects: A lightweight, modular, blazing-fast and user-friendly desktop environment. For more information on LXQt and the latest developments bringing it to Lubuntu, see here.
