I looked at it, first tried the ubuntu image, didnt work, then copied the files from XUBUNTU - it booted
didnt knew the password was ubuntu, took a few tries.
Desktop booted, after a brief BLANK/BALCK Screen - then the top/bottom panels were BLANK and never loaded any panels.
sudo raspi-config works, but didnt do some of the options I tried to change, Enable SSH, VNC and setting WIFI through it.
Right clicked on TOP bar, got the context menu, ADDED panels, Main menu and Network - WiFi worked, connected to network.
But now moving back to Pi 3B and Mate 16.04 - as I need to run ROS…
Can check more and test more if you have some specific things to check.
