I've installed fluxbox just to have a different session to check, and
yes there is the same delay also with fluxbox.

I think /etc/hosts is fine, it just lists the loopback address and the
hosts of my home lan.

When gdm was "waiting" I run:


$ ps ax | grep gdm
12108 ?        Ss     0:00 /usr/sbin/gdm --config=/etc/gdm/gdm-cdd.conf

I've never used pstack, and I hope these data could make sense to you,
because it's greek to me :-)

Many thanks for your answer.
