It is recommended that you read the latest release notes on our wiki.

Release 3

The OpenMandriva Lx teams are pleased to announce the availability of the release 3!

Detailed below are some of the advances that the distribution has incorporated since OpenMandriva Lx 2014.1. Apart from the enhancements 233 bug have been resolved since the 2014 release.

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're 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.

Important Note

The live media currently comes with no predefault mirrors. This means that there are currently no mirrors accessible to urpmi. The mirror list is updated/refreshed periodically.

It may be that you have installed this release very early, so the mirrorlist may not yet be due for update - so urpmi will refuse to work. There are two ways to correct this problem:

  1. Wait a few hours until the mirror list is due for an update.
  2. Force a refresh by running su -c 'rm -f /var/cache/urpmi/mirrors.cache', entering the root (administrator) password when prompted.

Recommended Hardware

OpenMandriva Lx 3 requires at least 1,5 GB of memory (min 1GB), at least 10 GB of hard drive space (see below for known issues with partitioning), and for best compositing performance a suitable accelerated 3D graphics card.

If you wish to run the live distribution (the option to Start OpenMandriva 3 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.

Releases are available for i586 and x86_64 architectures. ARM architectures are not available for this release.

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 2.1 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.


Where it is seen 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 precaustion 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.

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 (254mB) fat32 partition created at the start of the drive. 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 (Rufus) truncate the volume name. This breeaks the boot process.

urpmi rosa-imagewriter

Or, if you do not have OpenMandriva Lx:
Windows (32-bit)
Linux x86 (32 bit)
Linux x86_64 (64 bit)
Mac OS

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.

New Features and Major Changes

OpenMandriva Lx 3 is a new release.

LLVM/clang

OpenMandriva decided to give a go for a switch to LLVM/clang as a default compiler, and finally has replaced GCC. Over 90% of packages are rebuilded with LLVM/clang in our main repository.

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 infor can be found here.

Kernel

A new Kernel 3.18.11 nrJQL – a powerful variant of the 3.18.11 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 229. By default are enabled:

  • systemd-networkd
  • systemd-timedated
  • systemd-timesyncd
  • systemd-resolved

Xorg

We've upgraded Xorg to version 1.18.2, and Mesa to 11.2, 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).

We recommend that users change the composite manager in KDE from XRender to OpenGL mode. This gives transparency the proper blur effect. This also allows our theme and it's decorations to be shown at their best.

Wayland

We are working on many new and interesting shells using new display technology based on Wayland. Currently planned are:

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.

Desktop

The oma-welcome 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 5.6.0

We'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.

KF 5.x

We have implemented full KDE Framework that allows user to get all of benefits of Plasma 5 desktop.

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 alpha 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 4.4.2

The latest LibreOffice featuring much faster load times and many bug fixes.

Firefox 45.0.1

The latest firefox with it's new graphical interface and all the latest features.

You may wish to suspend desktop effects when Firefox is in full screen mode, as it speeds up scrolling.

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.

Sound

ALSA is updated to version 1.1.0

Pulseaudio version is 8.0, you can find more information about features here.

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 5.20.2 version. All perl related software in main repository has been rebuilt to meet new version.

Python

Python has been updated to 3.4.3 version and starting from now it became default python interpreter over python 2.x.

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

Upgrading to 3

Upgrading between releases always has the potential to cause some problems. Upgrading is supported and we do test upgrades, but due to the huge range of packages and hardware configurations that are possible, the upgrade may cause unexpected problems. Therefore we recommend that you always perform fully backup your system prior to any upgrading attempt, since there can be a chance for a loss of data. In particular be aware that upgrading between MDV-based packages and OMV-based packages may be the most problematic and should be avoided if possible.

We hope that upgrading between OpenMandriva Lx releases will become easier in the near future.

Upgrading from previous OpenMandriva Lx Releases

If you do NOT receive an upgrade notification from the Online Update applet, you may have to update your system.

If mdkapplet crashes trying to upgrade, you may have to update the packages on your system first.

If you still do not receive a notification (we may not have pushed it to all systems) or wish to do a manual upgrade, you may step through the following procedure.

As root, run the following commands:

urpmi.removemedia -a
urpmi.addmedia --distrib --mirrorlist 'http://downloads.openmandriva.org/mirrors/openmandriva.2015.0.ARCH.list'

Substitute ARCH with your architecture, e.g. i586 or x86_64.

Then run the following commands:

urpmi --auto --auto-select --replacefiles 2>&1 | tee /root/upgrade.log

Reboot when completed. The upgrade log is stored in /root/upgrade.log.

Upgrading from 2011.0

Please upgrade to 2013.0 first by following the procedures outlined in the 2013.0 release notes before upgrading to 3.

Changes to Hardware Support

Graphics Support

Graphics support has improved with the latest drivers however there are still issues with some hardware.

NVIDIA Graphics Cards

NVidia graphics cards are all 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. The reverse engineered nouveau driver gives moderately good support for these older cards and for some dual-screen work(Publishing) it is actually better as it supports screen rotation on a second monitor which is useful for monitors with rotatable screens.

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 Cards

Intel graphics cards are supported with the latest kernel we have, including newer 4th generation Intel graphics cards.

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

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.

Service responsible for 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 BETA release offers KFE Plasma 5, LXQt and xfce4 as desktop environments.

Media Sources

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. The usage of these packages vary by country - OpenMandriva Lx is not responsible for their usage! If you believe that their usage is unallowed in your country, please disable the restricted repositories.

Other Changes

Monitor EDID Loading

The "EDID ovverride" 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.

Errata

As with any release, there are still issues and bugs that may not have been resolved. This page documents those that may cause inconvenience and where possible details how they may be worked around.

Booting Live DVD/USB

If you have a problem booting the live image with some hardware please report a bug detailing your hardware and any observations that you make if you are affected by this problem.

Partitioning with Small Disks

When using the custom partitioning tool to divide up the hard disk/s be aware that there is a minimum size requirement a root partition that contains the /usr directory of at least 5.0Gb. If the partition is made smaller that this the partition manager will not function correctly.

Due to the adoption of systemd the use of a separate /usr partition is no longer possible. It is still permissible to have a separate /usr/local partition.

Workaround: If you receive an error message stating that the partition is smaller than the minimum requirement then do not try to resize it as this will fail; instead, use the auto-allocate function which will automatically create a partitioning scheme for you, which you may then delete or change to suit your own requirements. This will clear the error.

Local Network Sharing

The firewall service, firewalld is now enabled by default, if required it may be disabled via the OMA Contol Centre under the system entry. Additionally to aid local networking both nfs and samba ports are open over and above the usual ssh and other services.

Parental Controls

Parental Controls are currently non-functional.

Workaround: None available at the moment.

Partitioning: General Information

When using the custom partitioning tool to divide up the hard disk/s be aware that there is a minimum size requirement a root partition that contains the /usr directory of at least 5.0Gb. If the partition is made smaller that this the partition manager will not function correctly.

Due to the adoption of systemd the use of a separate /usr partition is no longer possible. It is still permissible to have a separate /usr/local partition.

Admin Privelidges: The wheel group

Please note that the first user created on the system is part of the wheel group, which allocates special privileges that are usually only allocated for the root user. Users in wheel can bypass certain password dialogues to change system settings.

Workaround: This is intended behaviour. If you wish to disable this, remove users from the wheel group.

Black Screen at Boot

There is an issue with systems that have two different graphics adapters but only one of them is operational. Typically this is a Nvidia GPU combined the either Intel or AMD/ATI. Due to the automated nature of driver selection in modern systems if the non-functional GPU is automatically selected then X will load the matching driver. Thus the working GPU never gets setup resulting in a black screen. We have recently added a new boot command line option to allow an Xorg driver to be blacklisted thus allowing the correct driver to be detected.

To use this feature you must edit the grub2 command line. You can do this by selecting your desired boot option and then pressing TAB. To the end of the line add the following:-

xorg.blacklist=<driver to blacklist>

To determine which driver needs to be blacklisted is probably best achieved by booting the system to a text mode and checking which driver has been loaded at boot time. A procedure for doing this is detailed below. In some circumstances this may not be possible and you will need to resort to your motherboard/Graphics card specifications or trial and error. It will be necessary to permanently add the line to the grub2 command line that boots the installation. This is described below.

There are other circumstances where a black screen may be encountered. For example if you wish to use the proprietary driver for your graphics adapter it may be necessary to inhibit the kernel mechanism that loads the free drivers. In these circumstances adding

nomodeset 

or

nokmsboot

to the kernel command line will normally be enough to allow installation of the OS or running with the manufacturers drivers . If necessary the command may be added permanently by editing /etc/default/grub at the GRUB_CMDLINE_LINUX_DEFAULT label and adding the required command. Then run update-grub2


To boot to text mode:-

1: Boot from the DVD/USB stick and at the grub selection screen select the livecd option and press TAB. Edit the grub command line by and add the command

"systemd.unit=multi-user.task nomodeset" 

to the end and boot the machine. This will bring you to a command prompt where you can login.

2: Login as root and then type lsmod | less and observe the output. Look for the loaded graphics driver by finding the drm entry the graphics driver will be listed here. It will be typically nouveau, radeon or i915 (there may be others). The name used here will be the name to add to the xorg.blacklist= parameter

Backlight Issues

There are some machines with Intel GPU's (Netbooks particularly) that may still give a black screen even with everything set up correctly; this is due to the screen backlight logic being inverted. This may be fixed by adding i915.invert_brightness=1 parameter to the boot command line. This may be needed in addition to the xorg.blacklist= parameter.

Boot to a dracut prompt

If this happens all is not lost. This may be indicative of the lack of disk driver for your hardware. Dracut indicates that it has produced a bug report which you can copy to a memory stick and then attach to a bug report you will need to mount your memory stick. Assuming it is FAT formatted then plug it in and type 'dmesg' the device name of your memory stick should be visible it will be in the form /dev/sd<x> the bracketed x will vary depending on how many drives have been found on your machine if for example you have one other drive then the entry might read /dev/sdb. Create a new directory /mnt with 'mkdir /mnt' then type 'mount -t vfat /dev/sdb1 /mnt' and the drive should be mounted. (Note the 1 added to the device name). You should then be able to copy files to your memory stick with 'cp <files> /mnt/' . Please take the trouble to report this type of problem as receiving these reports is the only way we can improve our distribution.

Contact, Bug Reporting, Discussion

You are invited to discuss this release on our:

Please report bugs to our bugtracker.

For us to get the most information about your situation, it is a wise idea to install omv-bug-report:

urpmi omv-bug-report

Then, as root:

omv-bug-report.sh

will generate an archive containing system information that can be attached to a bug or mailed to a maintainer. This will greatly assist them in the diagnosis of the problem being reported.
