Notes

This page is a companion to the Release Notes.

This page is currently reflecting RC release. Entries will only be removed when any new RC, and final ISOs is released.

Entries below prepended with "FIXED", have a released update. So if you experience a problem marked fixed, try to do a full update. Some issues may need logout/login or reboot. Some are install or upgrade issues.

Also a non listed issue you see may be fixed if you do a full update.

Note that we will be updating issues from the bugtracker, i.e rc1, rc2, FOR_ERRATA8, IN_ERRATA8, FOR_RELEASENOTES8 as they are decided.

Also see Release Notes Known issues and Bug reporting sections.

Boot

Live images

Installer images

32 bit installer must be on DVD to work as repository

After system install, the Classic Installer ISOs can be utilised as repository, to install software from without using internet.

The 64 bit ISO works for this both when placed on DVD and on a USB stick. The 32 bit ISO do not work as repository from USB.

Graphics

AMD/ATI

mga#28154 - Live media not booting with some Radeon HD GPU or system installed with Classic ISO.

For AMD graphic cards based on Southern Islands family (Tahiti, Pitcairn, Oland, Verde, Hainan) and Sea Islands family (Kaveri, Bonaire, Hawaii, Kabini, Mullins) we are now defaulting to the newer amdgpu driver instead of the older radeon, and want feedback if it works properly or not on your hardware.

If it does not work for you, you can fall back to the older driver by adding the following on kernel command line:

For Southern Island cards:

radeon.si_support=1 amdgpu.si_support=0

For Sea Islands cards:

radeon.cik_support=1 amdgpu.cik_support=0

Nvidia

Nvidia have neglected to fix security issues in their 340 series driver, so we had to drop it from official repos. See Release Notes.

Desktops

Plasma

Wayland session with Nvidia's 455 (current) nonfree-drivers is available by making sure that "nokmsboot" is removed and "nouveau.modeset=0" is passed to Kernel command line. Note mga#27296 - Plasma Wayland session broken

Compiz desktop effects is no longer compatible with Plasma. If you use it in Plasma on Mageia 7 then disable it in Mageia Control Center Hardware -> Configure 3D Desktop effects - before upgrade, and if you don't want Compiz for another desktop environment, uninstall it. After install/upgrade of Mageia, you find desktop effects at System Settings (icon in panel) -> Workspace -> Workspace Behavior -> Desktop Effects.

Dolphin right click extension kde-rootactions-servicemenu is removed as it is unmaintained upstream and have issues.

mga#27147 - Multi-users successive logins, plasmashell no longer runs log on to whatever user after going into sleep

mga#27183 - Default Mageia spectacle integration settings missing in plasma5 systemsettings - sometimes...

mga#27362 - startplasma-x11 spawns zombie process (may make it sluggish)

mga#28095 - Avatar Change not working on Classic Install Mageia 8 but does work on Live

mga#28287 - new plasma workspace does not allow unlocking of widgets when upgrading from older version. Plasma5 desktop and panel widgets cannot be locked/unlocked in Plasma version 5.18 onwards. This means that any such widgets locked before the upgrade cannot be unlocked after. So before upgrading, be sure to UNlock all such widgets. If you do find locked widgets after upgrading, this will unlock them: $ qdbus org.kde.plasmashell /PlasmaShell evaluateScript "lockCorona(false)"

mga#28299 - GTK apps complain about missing window_decorations.css under Plasma

FIXED mga#28311 - Dolphin 20.12.0 segfault while when opening a new tab while there's text in the search field

FIXED mga#28324 - dolphin seg faults

mga#28342 - No shadows on GTK menus in GTK apps under Plasma. - When the theme "Breeze" is set in Systemsettings5 => Application Style => Configure GNOME/GTK Application Style, there is no shadow in GTK right-click and GTK menus. Workaround: Set it to "Adwaita" (which is default).

GNOME

Wayland: By default GNOME uses the Wayland display server. Wayland is still not fully mature, and may not work well on some hardware. Normally GNOME will automatically fall back to using the X.org display server if Wayland fails to start, but in some cases this fails to happen. If the GNOME desktop fails to launch after completing the initial language and locale selection, or if you experience display problems, you can try forcing GNOME to use the X.org display server by adding nowayland to the boot options in the initial boot menu (press e to edit the boot options).

Network: By default the NetworkManager service is enabled in place of the old network management services. You can use the drop-down menu accessible from the top right corner of the GNOME desktop to perform any necessary network configuration. For wired connections, the network is usually configured automatically, and you don't need to do anything. For wireless networks, you will usually need to select an access point and, if it is password-protected, enter the password. Network configuration via the MCC/drakconnect should also work in most cases.

Cinnamon

FIXED mga#28129 (32 bit) Nemo hangs at start from launcher or terminal.

Xfce

mga#24134 - After login the display may show black and white bands or interesting effects for a couple of seconds.

mga#27795 - In Xfce, net_applet does not react to changes in connection status properly

Other

mga#26144 - lxqt broken icon theme as installed - Manual fix here.

Software

Applications that run as root fail to run in grahics mode

mga#28280 - Drakxtools fail to launch in GUI mode after configuring network

Mageia Control Center will fail to start in graphics mode if the hostname for the network is left at its default of localhost.

The current workarounds are to either specify a hostname other than "localhost" during network setup, or before starting MCC, as your normal user in a terminal enter

Konsole.png
[user@computer ~]$ xhost +si:localuser:root
localuser:root being added to access control list

A proper fix will be decided on and implemented before the final ISO images are produced.

This bug has also been shown to affect SDDM in some cases. mga#27601

Mageia Welcome

mga#28328 - Steam cannot be installed with the one-click button proposed with Mageia Welcome if 32bits repositories are not enabled, as it is the case by default. - 32 bit repositories should be enabled to complete the installation.

Flatpak

Plasma Discover and Gnome-software prefer Flatpak over Mageia RPM packages.

Various software

mga#28097 - xviewer seg fault, core dump on 32-bit; also, not in application menus

Miscellaneous

Printing

Printer duplicate - not a bug

You may see your printer shown twice. That is because you are shown all available printers on both local CUPS server (localhost) and all connected CUPS servers. So if you share a printer to the network, which is the default, it will be shown as two on the sharing computer. This behaviour is not specific to Mageia.

Workaround: Tell CUPS to not share the printer queue job on local network if you do not need to use it from another computer. See Mageia Control Center Section Hardware > Printing menu Server -> Settings.

Upgrade issues

Be sure to follow one of the procedures in Release Notes. Avoid screen saver interfering! mga#25251

Upgrade using DNF

Extra kernel flavour installed - DNF use a different method to select kernel flavour than Mageia installer. This may result in that a system that was using desktop kernel, after upgrade have both desktop and server installed, and server used. Easy fix: select at boot the desktop kernel, then uninstall server kernel. mga#28272

Removed packages

Generally, see at end of Release Notes.

VirtualBox

There is no longer a VirtualBox 32 bit host.

Various upgrade issues

Samba

mga#28042 - Upgrade to MGA8 Fails - ERROR:'script' failed for samba-client-4.10.18-1.1mga7.x86_64 - an update to fix this will land in Mageia 7.
