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.
Nvidia have neglected to fix security issues in their 340 series driver, so we had to drop it from official repos. See Release Notes.
1) 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 to edit the boot options).
2) 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.
Upgrade using dnf
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.
