OpenMandriva Lx 4.0 Errata - Known Issues

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.

As always users are encouraged to ask questions about anything you don't understand on our forum.


Web Browsers and some e-mail clients don't work on znver1 ISO

Some Web Browsers including default Falkon as well as Chromium and Firefox and Thunderbird e-mail client don't work on the znver1 'Live' ISO and installed znver1 system. This is due to 2 missing packages. To correct this problem install 'nss-shlibsign' and 'lib64freebl3'. To install from command line in Konsole is simply to run this:

$ sudo dnf install nss-shlibsign lib64freebl3

We apologize for any inconvenience users may suffer. This will be corrected for next release.

LibreOffice doesn't start on a few machines

There is a problem with LibreOffice startup observed on one machine so far. This seems to be caused by a problem in the Radeon Vega graphics driver.
The only known workaround is to disable OpenGL acceleration in LibreOffice.
Due to the small number of machines affected, we've opted not to make disabled acceleration the default setting.
To make an affected machine work, run libreoffice --safe-mode and select "Disable Hardware Acceleration (OpenGL, OpenCL)".
After this, LibreOffice should work normally.

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.

Users may use drivers from nvidia web site but they are not supported by OpenMandriva. These can't be supported by OpenMandriva for a number of reasons.

Installing and maintaining any proprietary nVidia drivers is solely the users option and responsibility.

Why doesn't urpmi work?

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. Also there are How To articles in our Forum in the Resources category such as this.

Where did OMCC/drakconf Control Center tool go?

OMCC/drakconf and drakxtools will be replaced with newer, more up to date, software. The first step in this process is dnfdragora available for user testing.
dnfdragora is a replacement for rpmdrake. More software will be added to upcoming releases.

Calamares installer error: /boot/efi esp flag is not set

There is an issue for some multi-boot users using "Manual Partitioning" on UEFI systems with existing partitions. Specifically an existing /boot/efi partition where Calamares sees the /boot/efi partition as incorrectly flagged. So far it appears that this issue affects only a handful of users. It has not been a common problem. Information we have to date suggests this might happen if one has a misaligned /boot/efi or some other similar minor partition error or with very early UEFI computers with something in the computer BIOS. Be assured we are aware of and actively investigating to come to a resolution of this issue.

This is what the Error Message will say if you encounter this:

An EFI system partition is necessary to start OpenMandriva Lx. A partition was configured with mount point /boot/efi but it's esp flag was not set. To set the flag go back and edit the partition. You can continue without setting the flag but your system may fail to start.

However when you go back you will see there is no esp flag to set. So how does the humble Linux multi-boot user correct this?

At this point cancel and close Calamares and open Konsole and do the following:

(Where the X in /dev/sdX is the letter of your chosen drive with /boot/efi partition.)

$ sudo fdisk /dev/sdX

$ p (and notice which is the efi partition)

$ t

(select the partition number of the efi partition)

$ 1

$ w

(Then to check to be sure)

$ p

(And check to be sure your /boot/efi partition is labeled under Type as EFI System)

$ quit

Once your /boot/efi partition is correctly labeled as EFI System return to Calamares installer and installation should proceed without error. If not please report on our Support forum.


There is a well known problem with some (especially newer) NVME SSD's and PCIE devices where the SSD may not be recognized. For our 'Live' ISO there is a workaround described in Release Notes.

Problem is known and being worked on by OpenMandriva developers and upstream developers.

On installed system user may wish to add that workaround to '/etc/default/grub' and run 'update-grub2' to make workaround global. You would use the one that you found to work on the 'Live' ISO.

If (PCIE ASPM=OFF) worked for you then add:


to the lines:



in /etc/default/grub and then run:

$ sudo update-grub2

If (NVME APST=OFF) worked then add instead:

Available Media

While our plan was, and still is, to provide LXQt-only and Basic GUI minimal ISO images, in addition to KDE Plasma desktop system, some unforeseen circumstances prevented us from having them ready at public release time.
