I missed one obvious clue, thinking that Xorg.log was the strategic place to look.
/var/log/messages (search olpc-dm) shows - "olpc-dm.service holdoff time over, scheduling restart" - and then "xauth: file /var/tmp/olpc-auth/.Xauthority does not exist" googling "Xauthority create olpc" does not give a good hit, but suggests I should learn olpc-utils better.
