So to be sure I know what steps make it work, and what I had to do to get things like Ethernet and sound working, here is the complete list of steps I went thru after starting over with an Ubuntu Server install for the Raspberry 4 - 19.10.1 (
http://cdimage.ubuntu.com/releases/19.1 ... pi3.img.xz).
sudo dhclient -v (To get Ethernet Connectivity)
sudo apt update && sudo apt upgrade -y
sudo apt install xubuntu-core^ slick-greeter
(Create /etc/lightdm/lightdm.conf)
sudo nano /etc/lightdm/lightdm.conf
(Add lines:)
[SeatDefaults]
greeter-session=slick-greeter
(Save and Exit)
sudo reboot
Once rebooted I can connect to a Wifi 2G Network fine, but the Ethernet Connection dosn't work unless you open a Terminal and Issue the "
sudo dhclient -v" command
(to add the FireFox Browser Open a Terminal and issue the following command:)
sudo apt-get install firefox
(to add the LibreOffice Open a Terminal and issue the following command:)
sudo apt-get install libreoffice-common
(to add the VLC Media Player Open a Terminal and issue the following command:)
sudo apt-get install vlc
(to add the Synaptic Package Manager Open a Terminal and issue the following command:)
sudo apt-get install synaptic
(Now use Synaptic to install Software store)
(Now use Synaptic to install Update Manager)
(After each reboot to have Ethernet connectivity you will need to open a terminal and issue the "
sudo dhclient -v" command).
(In /boot/firmware/usercfg.txt I added a line to allow sound on the HDMI monitor:
dtparam=audio=on. I accidentally found this while googling Raspberry Pi 4 sound driver)
