Yeah, I meant title==subject, I was hoping it was clear enough for everyone.
Why did you copy it ? ^^

That sounds like what is documented here, with the solution at the end:

$ apt show dbus-user-session
Package: dbus-user-session
Version: 1.12.24-0+deb11u1
[... some output snipped for brevity ...]
Description: simple interprocess messaging system (systemd --user integration)
  D-Bus is a message bus, used for sending messages between applications.
  Conceptually, it fits somewhere in between raw sockets and CORBA in
  terms of complexity.
  On systemd systems, this package opts in to the session model in which
  a user's session starts the first time they log in, and does not end
  until all their login sessions have ended. This model merges all
  parallel non-graphical login sessions (text mode, ssh, cron, etc.), and up
  to one graphical session, into a single "user-session" or "super-session"
  within which all background D-Bus services are shared.
  Multiple graphical sessions per user are not currently supported in this
  mode; as a result, it is particularly suitable for gdm, which responds to
  requests to open a parallel graphical session by switching to the existing
  graphical session and unlocking it.
  To retain dbus' traditional session semantics, in which login sessions
  are artificially isolated from each other, remove this package and install
  dbus-x11 instead.

Will keep that under the elbow, but it *seems* a systemd problem (see other posts, like the ycombinator link, first post is exactly my problem).
