What modules does your /etc/nsswitch.conf have registered for the
passwd, group, shadow and gshadow databases? A typical setup would look
like this:
passwd: files systemd
group: files systemd
shadow: files systemd
gshadow: files systemd
The new gdm version requires libnss-systemd ("systemd" in
/etc/nsswitch.conf) for its handling of dynamic creation/deletion of
temporary user IDs.
gdm3 Depends on libnss-systemd, and installing that package *should* set
it up in nsswitch.conf automatically, but one possible reason for the
gdm "greeter" (login prompt) not to start up successfully is that this
somehow hasn't happened.
The previous log was already with DEBUG_INVOCATION=1.
I'm surprised by this, I would have expected to see at least one
"GLib-DEBUG" message from gdm at some point in its lifetime.
