OpenMandriva Lx 3.01
The OpenMandriva Lx teams are pleased to announce the availability of OpenMandriva Lx 3.01!
Detailed below are some of the advances that the distribution has incorporated since OpenMandriva Lx 3.0.
Available Media
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.
Recommended Hardware
OpenMandriva Lx 3.01 requires at least 2.0 GB of memory (min 1,5GB), at least 10 GB of hard drive space (see below for known issues with partitioning).
If you wish to run the live distribution (the option to Start OpenMandriva Lx at the CD boot screen), you must have at minimum 1.5 GB of memory. At least 2 GB of memory is recommended for optimal performance.
Release is available for x86_64 architecture, The i586 and ARM architectures are being worked on, but are not yet available for this release.
Important Note
The KDE Plasma Desktop requires a 3D graphics card that supports OpenGL 2.0 or above
Virtual Machines
The same hardware requirements apply when running in virtual machines.
For VirtualBox, however, you must ALWAYS have at least 1536 MB of memory or OpenMandriva Lx will fail to boot.
Please ensure that VirtualBox is configured with "Enable PAE/NX" This option can be found under the System>Processor tab.
Also for VirtualBox you must install to a fresh VM, as trying to install to an existing one may fail. This recent problem is being investigated.
Note that if you use qemu, you may need to select an alternative graphics driver other than your distribution default or you will boot to a black screen.
Installer and EFI Support
This release of OpenMandriva Lx supports booting and installation with and without UEFI.
Best system installation experience is provided by Calamares 2.4.5 installer.
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. Calamares 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.
You should be able to boot and install OpenMandriva LX on UEFI machines.
Note that secure boot is NOT supported.
If you are installing beside Windows8 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 installs have been performed with no issues. We would welcome any feedback in this area.
Please see the notes on partitioning here and here
EFI Partitioning
If you wish to to perform an EFI install on an existing MBR disk it will be necessary to convert the disks 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 tables. 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 (330mB) 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 in Calamares otherwise the install will fail. If you fail to observe these steps 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.
Booting from USB
It is also possible to boot this release from a USB storage device. To transfer the live/installation you may use the ROSA Image Writer available from our repos.
Please do not use other usb-writing tools as some Windows tools (e.g. Rufus) truncate the volume name. This breaks the boot process.
urpmi rosa-imagewriter
Or, if you do not have OpenMandriva Lx yet, you can get ROSA Image Writer download links at this page
http://wiki.rosalab.ru/en/index.php/ROSA_ImageWriter
At least 2GB of flash drive capacity is recommended. Persistent storage is not necessary. Note that this will erase everything on your USB!
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.
Booting from ISO file
Grub2 entry ( to be added in /boot/grub2/grub.cfg)

}
}
New Features and Major Changes
OpenMandriva Lx 3.0 is a new release.
LLVM/clang
OpenMandriva decided to give a go for a switch to LLVM/clang 3.9.1 as the default compiler, and finally has replaced GCC. Over 90% of packages in our main repository are built with LLVM/clang.
Benefits for end user:
- Fast compiles and Low Memory Use
- Expressive Diagnostics
- GCC Compatibility
- Better object code generation compared to others
- Object code is optimized for its size
More information can be found here.
Kernel
OpenMandriva Lx uses the latest stable kernel, 4.9.0, by default with BFQ set up as a default I/O scheduler to achieve best performance.
OpenMandriva Lx also features kernel 4.1.18 nrJQL – a powerful variant of the 4.1.18 kernel that has been configured with desktop system performance, responsiveness, and realtime capabilities, in mind.
The new NRJ mode adds CPU and RCU full Preemption and Boost mode, the QL mode adds patchsets which combine to provide further optimisations, including BFS CPU task scheduler, BFQ disk I/O scheduler, UKSM memory management, TOI for suspension and hibernation.
This kernel version is enabled with kernel keys necessary to use the “EDID ovverride” feature, with this we should be able to override an incorrect screen EDID with boot time options, we have included EDIDBINS in the ISOs, a package containing 5 basic firmwares for the most common resolutions so that users may force different resolutions than the ones detected automatically by X.
The CONFIG_ACPI_CUSTOM_DSDT key allows loading of a customised acpi table. Details will be found on our Wiki in the kernel pages.
Highlight:
HT/SMT NICE feature added and enabled by default for a better responsiveness and realtime behaviour on all PC with HT (Hyper-Thread), improving performance of foreground applications at the expense of background ones.
Your desktop / gui / applications will remain fast even if you run folding@home, mprime, seti@home etc.
A more effective and precise control on the nice levels of server apps for its proper balancing and tuneups.
Please, see: https://wiki.openmandriva.org/en/Kernel for more information.
systemd
Default init system is systemd with version 232. By default are enabled:
- systemd-networkd
- systemd-timedated
- systemd-timesyncd
- systemd-resolved
Xorg
We have upgraded Xorg to version 1.19.0, and Mesa to 13.0.2, 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).
Wayland
We are working on many new and interesting shells using new display technology based on Wayland 1.12.0 version.
For now Weston and KDE Plasma 5 are working out of box. KDE Plasma 5 running on wayland is still experimental and not recommended for daily use.
libinput
All the input devices like keyboard, mouse, touchpad and others are now handled though libinput 1.5.4 version library by default.
Desktop
The oma-welcome, or Welcome to OpenMandriva Lx has been updated to reflect the new version. This application introduces 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 a desktop.
KDE Plasma 5.8.4
We have ve upgraded to the latest and greatest version of the KDE Plasma desktop. If you don't know what KDE Plasma is, learn more at their website.
KDE Frameworks are updated to 5.29.0 version.
KDE Applications are updated to 16.08.3 version.
We are using Plasma-discover as a main tool for updating distibution. Plasma-discover is a Qt5 frontend for PackageKit.
Our distribution is running with Qt 5.6.2 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.
KF 5.29.0
We have implemented full KDE Framework that allows user to get all of benefits of Plasma 5 desktop.
Calligra Suite 3.0.0
Calligra Suite is a graphic art and office suite written in Qt4 and supports KDE Plasma 5. (A port to Qt5 is currently in progress, but not yet included in the 3.0 release). It is possible to install whole calligra suite after installation is finished.
Krita 3.1.1
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
SDDM is new and lightweight displaymanager, written in Qt5 with QML and provides new features and benefits to enduser, compared to KDM.
LXQt 0.10.0
We have prepared LXQt for our Release. LXQt is a lightweight desktop fully written in Qt5.
By default SDDM is used as display manager.
xfce4 4.12.0
xfce4 is very lightweight environment based on GTK+2.0 and GTK+3.0, featuring speed, low request on resources combined with great look.
LibreOffice 5.2.3
The latest LibreOffice featuring much faster load times and many bug fixes.

You may wish to suspend desktop effects when running Firefox is in full screen mode, as it speeds up scrolling.
Chromium 55.0.2883.75
A Chromium web browser is available to install it on running system either by using urpmi, discover or rpmdrake.
urpmi chromium-browser-stable
If you wish to try an experimental version with newer features (but not quite the stability), you can also try
urpmi chromium-browser-dev
The -stable and -dev versions can coexist on the same installation.
Java 8
The OpenMandriva Java stack has been entirely rebuilt to version 8 and is completely functional.
We currently provide Eclipse Luna by default.
Printing
Improved support for printing, with an emphasis on the latest HP printers. Printing support is based on Cups 2.1.3 and ghostscript 9.19.
Sound
ALSA is updated to version 1.1.3
Pulseaudio version is 9.0, you can find more information about features here.
Multimedia
The SMPlayer media player is now 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.
Cloud service
We added support for owncloud.org via owncloudclient package.
LCMS
We have updated our LCMS to version 2.x, also all software which was dependant on older library has been rebuilt to meet new one.
libarchive
We have decided to make better use of libarchive, and starting from this 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
Perl base package has been updated to 5.20.3 version. All perl related software in main repository has been rebuilt to meet new version.
Python
Python has been updated to 3.4.4 version and starting from now it became default python interpreter over python 2.x.
Virtualization
We provide support for:
- qemu
- docker
- virtualbox
You can install and run these out of the box.
Games
We provide many of the games which have been ported to Linux. By using of PlayOnLinux you can play games usually available only on the Windows(tm) platform. Of course Steam package is also available and can be installed using urpmi, rpmdrake or plasma-discover.
To give it a go, enable the non-free repositories, and
urpmi steam
More information can be found on our page dedicated to games.
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 3.0 Releases
Upgrade is simple, just check your discover, or rpmdrake for new packages and install them. You can also run this command from your root:
urpmi --auto-update
Upgrading from OpenMandriva Lx 2014.x and older
Currently for OpenMandriva Lx 2014.x and older a fresh install is recommended.
Changes to Hardware Support
Graphics Support
Graphics support has improved with the latest drivers however there are still issues with some hardware.
To access XFDrake, the DrakX video configuration tool go to Om-Welcome>Configure>Configure video drivers or go to Configure your Computer>Hardware>Set up the graphical server.
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's binary driver as it supports screen rotation on a second monitor, which is useful for monitors with rotatable screens.
NVIDIA's binary drivers (which provide better performance and better support for the very latest NVIDIA GPUs) are currently supported by the XFDrake, the DrakX video configuration tool. In some cases it may be necessary to install older drivers using the command line. These drivers are available from the OpenMandriva repositories.
ATI Graphics Cards
The latest ATI graphics cards are supported; however, we have not had any concrete feedback about its usage. Your mileage may vary.
If you are using Radeon HD7770 or if you experience a black screen at boot and you know that you have an ATI/AMD grahics card please add the command below to the grub2 cmdline:-
xorg.blacklist=ati
To do this at when booting the iso press the "TAB" key; the kernel bootline will be displayed at the bottom of the screen, go to the end of it and add any options required there. Press enter to boot. If you need to enter a kernel parameter while boot an installed system the procedure is slightly different. At the boot screen press the "E" key and this will bring up the Grub editor. Search for the first line that begins with "linux" go to the end of it and add the option there. To boot press F10.
Intel Graphics Chips
Intel graphics chips are fully supported.
For 6th generation Skylake GPUs, you should use kernel 4.6 instead of 4.1.18-nrjQL.
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 file a bug at issues.openmandriva.org
Laptops with dual graphics cards
Please report any issues experienced
Changes to Installation
Installer
We are using Calamares as our default installer.
Calamares is an installer framework. By design it is very customizable, in order to satisfy a wide variety of needs and use cases.
Calamares aims to be easy, usable, beautiful, pragmatic, inclusive and distribution-agnostic.
Unused Hardware & Language Removal
This feature has been re-enabled. It prompts you to run it at first boot, and you may run it any time afterwards from the oma-welcome application (Welcome to OpenMandriva Lx).
Changes to the DrakX suite of tools
Boot Configuration
We now default to using grub2-editor to control the boot loader.
Proprietary Drivers
We now install proprietary drivers for nVIDIA and AMD correctly.
Firewall
We have deprecated drakfirewall in favour of 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 KDE Plasma 5, LXQt and xfce4 as desktop environments.
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.
contrib
contrib represents community maintained packages. These are not supported by the core OpenMandriva Lx team, and depend on package maintainers to update it.
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.
Other Changes
Monitor EDID Loading
The "EDID override" feature is now available and allows a monitor with incorrect (or no) EDID to be enabled at kernel boot A package "edidbins" has been included in the ISOs which provided five binary files to support the most common resolutions. These may be called from the kernel command line at boot such that screen resolution may be force to that which the user desires. Obviously a facility like this should be used with care as it has the potential to damage your monitor. In order to enable one of the supplied edid's you need to add the following line to your kernel command line "drm_kms_helper.edid_firmware=edid/1280x1024.bin" obviously you can select your resolution from those supplied which are.
1024x768 1280x1024 1600x1200 1680x1050 1920x1080
As things currently stand these resolutions are available as soon as the root directory is mounted. If you want these resolutions for plymouth then you will need to incorporate the edid binary file in the initramfs. Dracut the image builder does not currently support this. The current approach would be to unpack the initramfs, add the necessary files and then repack.
