Hello everyone
I'm an admin of the Geekos Italia group on Telegram, a support group for
openSUSE. 
We have see that, during the installation, most people do not compile the
network section, they press "forward" "forward" "forward". In doing so, it does
not correctly configure the network and at first reboot start by default wicked
instead of Network Manager.
we would like to suggest you to modify the defautl settings, so that they are a
little clearer and that you can configure Network Manager.
Thanks in advance for your prompt reply.
