Hello Bernhard,
thanks for replying and the hints, see the attachment, sorry about the
grave flag, feel free to change it (looking at the stack may be
something related to the atspi upgrade, I'll try a downgrade, perhaps
not a lightdm bug), currently I can login booting at level 3 and then
startx manually.
Kind regards
Alex
