SAfter the reboot, the fonts were ok and I was able to edit the /etc/hosts file and /etc/resolv.conf which i then rendered immune to NM and cohorts with a chattr +i,
Then I ran whatever acts like NM, set it up for static and it pings yahoo.com .
Set /etc/hostname to match the hosts file for that card and rebooted. And I finally found where to set the default desktop to xfce4, then took that u-sd to another m5 and edited the hostname, rebooted and its still working, running octoprint to drive a new 3d printer I got setup yesterday.
But despite installing ALL of the xfce4 stuff, the system won't change to it, and the screenblanker is still an instant crash switch, nothing will wake it back up.
This installer works, but leaves out stuff to allow another desktop that actually works to be switched to. Get rid of the graphical app launcher in favor of xfce4's menu's, and make the screen blanker work w/o killing an app the gui started. There is no way in armbian-config, nor in settings to chose which desktop. I have no clue what I did to the first one I posted about to get xfce4 to work.
Oh, and a sudo reboot is actually a full powerdown, the power must be recycled to reboot it. That also needs fixed.
Thank you for the helpful responses to other questions of mine.
Take care & stay well everybody.
