I'm trying to configure Ubuntu 20.04 on my Raspberry Pi 4 without success.
I've tried to use XFCE installing xubuntu-desktop. Everything works without the network manager which says my wifi device isn't ready even if I am online (because I've edited the network-config file). So I cannot change network and Cockpit cannot identify it.
I've created a new SD and this time I've tried to use KDE installing kubuntu-desktop. If I choose LightDM then I can see the login screen but I've receive the error "Failed to start session". If I choose sddm I cannot reach the login screen. Moreover ssh isn't working even if the service is active.
I've followed the official tutorial, nothing more.
I've found a partial solution in other request. To make kubuntu boots correctly tou have to edit the file /boot/firmware/syscfg.txt adding this lines
I don't know why I cannot see wifi networks even if I'm on line but I'll ask this in another question because is more specific.
