lightdm does not add seats after full system upgrade

Hi,
after a very long time I recently did a full system upgrade on one of my machines. Since that update, lightdm will not start any GUI, the /var/log/lightdm/lightdm.log looks like this:

[+0.00s] DEBUG: Logging to /var/log/lightdm/lightdm.log

# lightdm --show-config
   [LightDM]
A  start-default-seat=true
A  run-directory=/run/lightdm

   [Seat:*]
A  session-wrapper=/etc/lightdm/Xsession

Sources:
A  /etc/lightdm/lightdm.conf

The start-default-seat option was first not set, I uncommented it without any effect. No other log files get modified, no entries in the journal. What am I missing?

What's the full journal for a boot?

journalctl -b 0  | curl -F 'file=@-' 0x0.st

Why I run Arch? To "BTW I run Arch" the guy one grade younger.
And to let my siblings and cousins laugh at Arsch Linux...
