Warn01.png These Release Notes are a work in progress and can and will change as we develop OpenMandriva Lx 4


This is a RC product, and it is not aimed to be used in a production environment. It is released for testing and bug hunting. It may have problems. If you download and test this product, please report your findings and problems in the forum and in our issue tracking system. Thank you very much.

OpenMandriva Lx 4.0 RC

The OpenMandriva Lx teams are pleased to announce the availability of OpenMandriva Lx 4.0 RC. OpenMandriva Lx 4.0 is a new release. In order to keep current with latest changes in Linux, computer security issues, and computer code writing there are major changes in OM Lx4.

Detailed below are some of the advances that the distribution has incorporated since OpenMandriva Lx 3.03.


Available Media

Warn01.pngThis section is a work in progress and changes can and will be made as development of OM Lx 4 proceeds.

This release is available as a live media DVD, downloadable in ISO format. These are available on our downloads page.

Live media means you are able to run OpenMandriva Lx straight from a DVD or memory stick (see below) and try it before installing it. You may also install the system to hard disk either from the running live image or from the boot manager.

For the RC release, only the KDE Plasma edition is available:

1. KDE Plasma desktop only full featured (Includes applications that will do most things for most users including multimedia and office software.)

As we get closer to the final release, we're also planning to release Basic and text-only versions (Plans subject to change):

2. Basic GUI with minimal desktop and only basic system packages with Falkon browser.
The concept is for user to then install only packages they wish to use after installing basic system. Also for users with less robust hardware.

3. Text only
Just a minimal system without GUI, e.g. as a base for installing servers. This (obviously) expects the user to be able to handle command line interfaces.

All versions are released for several architectures:

x86_64 Runs on any 64-bit x86 machine - this covers virtually all currently available PC hardware.

znver1 znver1 is a special build for current AMD processors (Ryzen/ThreadRipper/EPYC). While the generic x86_64 version will run on znver1 compatible processors, the znver1 build is known to be both faster and smaller, by optimizing specifically for znver1 processors. We recommend using this build on hardware with current AMD processors.

aarch64 64-bit ARM processors. We currently make builds available for Raspberry Pi and DragonBoard 410c boards. At the moment, these boards work well in text mode, but the X server doesn't come up. Unlike Raspbian, the OpenMandriva version for Raspberry Pi is a full native 64-bit OS that doesn't use 32-bit components.

We are also working on armv7hnl (32-bit ARM processors with NEON unit) and riscv64 (RISC-V boards such as SiFive Unleashed) builds. The armv7hnl build is essentially ready to use (packages are available, but there is currently no install image).

Recommended Hardware

OpenMandriva Lx 4.0 requires at least 2.0 GB of memory, at least 10 GB of hard drive space (see below for known issues with partitioning).

Release is available for x86_64, znver1 and aarch64 architectures, the 32-bit ARM and RISC-V architectures are being worked on, but are not yet available for this release.

Important Note: Graphics Hardware

The KDE Plasma Desktop requires a 3D graphics card that supports OpenGL 2.0 or above. We recommend using AMD, Intel, Adreno or VC4 graphics chips.

Internet Connection

Calamares Installer checks if an Internet connection is available, but OpenMandriva Lx 4 will install just fine even without. It is perfectly OK to simply install as you normally would and proceed to use your new system as normal.

Updating such a system would require being temporarily connected to the internet or downloading the packages elsewhere and transferring them to the installed system and installing the updated packages. But as you are not connected to the internet you could simply use the system and not update for how ever long you see fit.

Virtual Machines

At this time the only virtualization software that OMLx ISOs are tested on is VirtualBox. The same hardware requirements apply when running in virtual machines.

For VirtualBox, however, you must always have at least 2048 MB of memory or OpenMandriva Lx will fail to boot.

Also for VirtualBox it is advisable to install to a fresh VM, as trying to install to an existing one may occasionally fail.

What is Calamares ?

Calamares is an installer framework. By design it is very customizable, in order to satisfy a wide variety of needs and use cases. It aims to be easy, usable, beautiful, pragmatic, inclusive and distribution-agnostic.
Calamares includes an advanced partitioning feature, with support for both manual and automated partitioning operations. It is the first installer with an automated “Replace Partition” option, which makes it easy to reuse a partition over and over for distribution testing.


At this time partitioning LVM and Raid setups with Calamares (the installer) is NOT supported.

Installer and EFI Support

This release of OpenMandriva Lx supports booting and installation with and without UEFI.

Note that secure boot is NOT supported.

If you wish to perform an EFI installation on an existing MBR disk it will be necessary to convert the disk partition table to the newer GPT partitioning scheme. To do this you need to use the gdisk tool. A typical invocation would be 'gdisk /dev/sda': the existing partition table will be converted in memory to the GPT scheme. Warnings will be issued about potential data loss, the disk will not be altered until you write the partition table by pressing "w". You are advised to back up any important data.

There may be occasions where the conversion cannot be performed, this will usually be due to insufficient space at the beginning or end of the disk to write the partition table. It may be necessary to delete or resize a partition to create the needed space, gparted is your friend in these circumstances.

There is still a need to create an efi partition to contain the boot equipment and this must be created while running the Calamares installer. When the installer reaches the partitioning stage the / (root) partition should be removed and a small (330 MB) FAT16 or FAT32 partition created at the start of the drive. If diskspace is critical then a smaller partition may be used, but be sure to set it as FAT16 or FAT32 in Calamares otherwise the installation will fail. If you fail to observe these steps the installation of the boot loader will fail. Subsequently partition the disk in the normal way. Please share your experiences on the forums so that we may improve this aspect of the installation.

If you are installing beside Windows 8, 8.1, 10 or similar EFI booted OS as a precaution please ensure that you have recovery disks and you have backed up any important data. Our testing has been limited with this configuration, but successful installations have been performed with no issues. We would welcome any feedback in this area.

Changing Partition Type

Please note that Calamares cannot convert one partition type to another and preserve partition data. If you run Calamares from the live image it is not possible to change an existing partition type. Trying to do this generates an error message. In order to do this you must first delete the partition and recreate it as the type that you wish.

Booting from USB

It is also possible to boot this release from an USB storage device. To transfer the live/installation image you may:

- Use the ROSA Image Writer available from our repos

sudo dnf --refresh install rosa-imagewriter

Or, if you do not have OpenMandriva Lx yet, you can get ROSA Image Writer download links at this page
At least 4 GB of flash drive capacity is recommended. Persistent storage is not necessary. Note that this will erase everything on your USB!

Please do not use other usb-writing tools as some Windows tools (e.g. Rufus) truncate the volume name. This breaks the boot process.

- Via dd

You may alternatively dd the image to your USB stick:

dd if=<iso_name> of=<usb_drive> bs=4M

Replace <iso_name> with the path to the ISO and <usb_drive> with the device node of the USB drive, i.e. /dev/sdb.

SUSE Studio ImageWriter has also been tested and works for burning ISO images to USB storage device.

Booting from ISO file

Grub2 entry ( to be added in /boot/grub2/grub.cfg)

submenu "OpenMandriva (64 bit)" {
        set isofile=/home/user/OpenMandrivaLx.4.0-PLASMA.x86_64.iso
        set isoname=OpenMandrivaLx_4.0
        loopback loop $isofile

        menuentry "OpenMandriva" {
                linux (loop)/boot/vmlinuz0 root=live:LABEL=${isoname} iso-scan/filename=${isofile} rd.live.image toram --
                initrd (loop)/boot/liveinitrd.img


New Features and Major Changes

OpenMandriva Lx 4.0 is a new release. In order to keep current with latest changes in Linux, computer security issues, and computer code writing there are major changes in OM Lx4.

Package Management (change from URPMI to DNF)

Major changes for OM Lx 4 include switching from rpm5/URPMI to rpm.org/DNF for package management. This will require users to get used to new commands if they use command line, DNF. There is an overlay package for those used to urpmi/urpme called dnf-URPM. It will translate a lot of the more common urpmi and urpme commands to dnf while users get use to the dnf commands. This is meant to be a transition package while users get used to dnf. This package will need to be installed by user. To install dnf-URPM open Konsole and run:

   sudo dnf install dnf-URPM

In addition to dnfdragora mentioned above Discover is working with dnf.


OpenMandriva provides LLVM/clang 8.0.1 as the default compiler, GCC is also available. Over 90% of packages in our main repository are now built with LLVM/clang.

Benefits for end user:

  • Faster compiles and Low Memory Use
  • Expressive Diagnostics
  • GCC Compatibility
  • Better object code generation compared to others
  • Object code is optimized for its size
  • OpenMP support enabled by default

More information can be found here.


OpenMandriva Lx uses the latest stable kernel, 5.1.0, by default BFQ is set up as a default I/O scheduler to achieve best performance.
By default an UKSM is enabled to manage memory efficiently.


Default init system is systemd with version 240


We have upgraded Xorg to version 1.20.4, and Mesa to 19.0.3, which brings the latest free drivers for the best performance. A Compose cache is now incorporated which speeds up application startup time and reduces memory usage especially in locales with large Compose tables (e.g. all UTF-8 locales).

We are using modesetting driver by default for nVIDIA, Intel and AMD graphics cards as well as Adreno GPUs.

With end of 02 October 2017 a S3TC patent has expired, and we have included S3TC texture compression in our Mesa.


We are working on many new and interesting shells using new display technology based on Wayland 1.17 version.
KDE Plasma 5 running on wayland is still experimental and not recommended for daily use. Testing and feedback of Wayland is welcome.


All the input devices like keyboard, mouse, touchpad and others are now handled though libinput 1.13.1 version library by default.


The oma-welcome or Welcome to OpenMandriva Lx application introduces the users to OpenMandriva Lx and shows them some of the features we have, as well as providing quick links to common tasks such as updating, installing new software, and configuring the desktop.

KDE Plasma 5.15.5

We have upgraded to the latest and greatest version of the KDE Plasma desktop. Learn more at KDE Plasma website.
KDE Frameworks are updated to 5.57.0 version. We have implemented full KDE Frameworks that allows user to get all of benefits of Plasma 5 desktop
KDE Applications are updated to 19.04.1

Our distribution is running with Qt 5.12 version.

Important notice! Plasma 5 make heavy use of Qt5 OpenGL. This means that the minimal system requirement is to have a graphics card that can support OpenGL 2.0 or newer version.

Calligra Suite 3.1.0

Calligra Suite is a graphic art and office suite written in Qt5 and supports KDE Plasma 5. It is possible to install whole calligra suite after installation is finished.

Krita 4.1.8

Krita is a creative sketching and painting application. It was part of Calligra up to version 2.9 and became a project independent from Calligra since then. It has already been ported to Qt5 and is included in the install image.


SDDM is a new and lightweight displaymanager written in Qt5 with QML and provides new features and benefits to enduser compared to KDM.

LXQt 0.14.0

We have prepared LXQt for our Release. LXQt is a lightweight desktop fully written in Qt5.

By default SDDM is used as display manager.

LibreOffice 6.2.4

The latest LibreOffice featuring much faster load times and many bug fixes.
LibreOffice 6.2.4 has much improved KDE Plasma integration.

Falkon 3.1.0

Falkon is a full featured web browser using Qt5WebEngine as a rendering engine. More information can be found here.

We encourage you to give Falkon a try as a new experience in the web browsers world.

Firefox 66.0.2

The latest Firefox Quantum with its new graphical interface and all the latest features.
You may wish to suspend desktop effects when running Firefox is in full screen mode, as it speeds up scrolling.

Chromium 74.0

A Chromium web browser is available to install it on running system either by using dnf, Discover or dnfdragora.

sudo dnf --refresh install chromium-browser-stable

If you wish to try an experimental version with newer features (but not quite the stability), you can also try

sudo dnf --refresh install chromium-browser-dev

The -stable and -dev versions can coexist on the same installation.

Java 12

The OpenMandriva Lx Java stack has been rebuilt on top of OpenJDK 12, and we have added support for Java Modules (jigsaw) and JAR libraries in the RPM provides/requires generators. We've also started adding module information (module-info.class) to packages providing JAR libraries. Migrating the remaining Java packages to newer systems will happen over the next releases (adding module support to any related package that gets an update). This should enable much better packaging of Java related packages in the future.


Printing support is based on Cups 2.2.10 and ghostscript 9.26.


ALSA is updated to version 1.1.8

Pulseaudio version is 12.2, you can find more information about features here.


The SMPlayer media player is included, using MPV as its default backend. If you live in a country that allows it, you may want to install the various codecs from the restricted repository for improved codec support.

We have enabled LAME support by default. With 2017 start all the patents related to MP3 are expired. By default our ffmpeg, gstreamer, and other media frameworks now supports LAME.


We have decided to make better use of libarchive, and starting from OM Lx 3 release by default we use:

  • bsdtar as a default tar program
  • bsdcpio as a default cpio program

Detailed features and benefits can be found here.


Perl base package has been updated to 5.28 version. All perl related software in main repository has been rebuilt to meet new version.


Python has been updated to 3.7.3 version and starting from now it became the default python interpreter over python 2.x.


We provide support for:

  • qemu
  • docker
  • virtualbox

You can install and run these out of the box.


We provide many of the games which have been developed for or ported to Linux.
By using of PlayOnLinux you can also play games usually available only on the Windows(tm) platform.
Of course Steam package is also available and can be installed using dnf, dnfdragora or plasma-discover.

To give it a go, enable the non-free repositories, and

sudo dnf install steam

ISO build tools

Previously livecd-tools were used to build OpenMandriva ISO images. Due to code complication and its limits, we moved to build own ISO image build tool.

omdv-build-iso is written as a bash shell script, which works out of box on ABF and in userland.

Upgrading from previous OpenMandriva Lx Releases

Currently a fresh install is recommended.

In order to keep current with latest changes in Linux, computer security issues, and computer code writing there are major changes in OM Lx4. A Fresh install is recommended. Upgrading from OM Lx 3 is not recommended. We strongly advise not to try upgrading from earlier versions. If you want to try upgrading anyway, make sure you've backed up all your data, and try the script available here.

Changes to Hardware Support

Graphics Support

Graphics support has improved with the latest drivers. We managed to reduce issues by using by default DRM subsystem and modesetting driver for AMD, intel and nVIDIA graphics cards.

If any users have special needs they will need to be configured from command line. If you need help please contact us at our forum or IRC room.

NVIDIA Graphics Cards

This release includes the reverse engineered nouveau driver, which gives moderately good support for most NVIDIA cards. For some dual-screen work it is actually better than NVIDIA binary driver as it supports screen rotation on a second monitor, which is useful for monitors with rotatable screens.

The drivers from nvidia website are not supported. This is not possible for a number or reasons.

We strongly recommend against using the proprietary drivers. They are impossible to support, and break frequently. If you install them, you do so at your own risk.

AMD/ATI Graphics Cards

AMD closed source driver is not supported (abandoned upstream) , Open source drivers are fully supported and only limited by Kernel/mesa BUGS or missing upstream (AMD) firmwares for newer Cards.

If you need help please contact us at our forum or IRC room.

Intel Graphics Chips

Intel graphics chips are fully supported.

Miscellaneous Graphic Cards

We have not had feedback from users. Should you have an unusual graphics card that is not performing as it should please contact us at our forum or IRC room. If issue persists please file a bug at issues.openmandriva.org.

Proprietary Drivers

Proprietary drivers not available for Lx 4 RC release. When they are available user will need to install and configure these from command line.

The drivers from nvidia web site are not supported. This is not possible for a number or reasons.


We have since OM Lx 3 used firewall-config, which relies on firewalld.

The service responsible for starting the firewall is enabled by default.

Booting with systemd

Systemd has now been moved into the initramfs and the result is super-fast booting. Switching runlevels has changed. Instead of adding the target runlevel, as before, there are now specific boot options. Namely, the following options must be appended to the kernel command line:

  • Rescue Mode: systemd.unit=rescue.target
  • Text Mode: systemd.unit=multi-user.target
  • Graphical Mode: systemd.unit=graphical.target

Desktop Environments

This release offers the KDE Plasma 5 desktop environment. LXQt is available in repos for users to install and test.

Media Sources

  • main

main is the core packages maintained by the OpenMandriva Lx team. This includes anything included in the install images as well as many more applications considered important.

  • unsupported

unsupported represents community maintained packages. These are not supported by the core OpenMandriva Lx team, and depend on package maintainers to update it. There are many packages in unsupported that will not install and others that install but do not work properly. Users are welcome to use whatever they find in this repository that is working.

  • restricted

restricted contains libraries that aren't installed by default due to legal concerns (such as patent issues). The usage of these packages vary by country - OpenMandriva Lx is not responsible for their usage! If you believe that their usage is disallowed in your country, please disable the restricted repositories.

  • non-free

non-free contains applications and drivers that are distributable, but do not meet the definitions of Free Software. While we can adjust the packaging of such applications, we do not have the source code and therefore can not fix problems caused by anything in this repository.

Helping the Project

The OpenMandriva development teams (Cooker & QA) are always looking for new contributors to assist in creating and maintaining packages and to assist bugfixing and testing. You are welcome to join us and help us in this work which is not only rewarding but also tremendous fun!

If you feel that your talents do not lie in the realm of software, then the OpenMandriva Workshop group, which is made up from the artwork, documentation, translation and Communication teams, is always open for the submissions of artwork and translations. New contributors who would like to help with these wide-ranging tasks should see the wiki for more details, and to learn how to join! Alternatively you may use our Forum.

It also costs time and money to keep our servers up and running. If you can, please donate to keep the lights on!
