What I ment was to receive (after booting) a login prompt in tty1 console;
then, if and when I need it switch to a new tty and call 'startx'
Michael's reply was perfect: it did exactly what I wanted ;-)

I'll keep in mind your suggestions: for the time being I'm not sure I
understand them well.

Many thanks to you all (Greg, Michael and youself) for the rapid and
efficient answers.

After upgrading to Stretch I'm unable to find a way to boot with no GUI.

You haven't provided your meaning for "text mode".

Greg and Michael's replies answer how to stop booting to a GUI login manager.

If instead what you wish is to avoid seeing any GUI effects, but do want to see 
boot messages from kernel and scripts as init proceeds, you need to ensure they 
have not been turned off by quiet or splash parameters on the kernel cmdline. 
Also, Plymouth may have been installed, which is a more sophisticated form of 
GUI splash during boot. Maybe all you need to do is purge Plymouth, and/or 
eliminate quiet and/or splash from your kernel cmdline (purge them from both 
GRUB_CMDLINE_LINUX_DEFAULT= and GRUB_CMDLINE_LINUX= in /etc/default/grub, then 
run update-grub).

To temporarily boot into text mode, edit the kernel command line in grub
and add "systemd.unit=multi-user.target"

If you want to make this change permanent, run "systemct set-default
multi-user.target"

The default is graphical.target, which will start your display manager,
like gdm3.

Michael

The easiest way is to remove whatever display manager is running by
default.  This works in every version of Debian and is super easy.

However, some people want to keep the display manager installed, but
prevent it from running at boot time.  This is much more difficult
and will involve understanding how your init system works.

In jessie and stretch, the default init system is called "systemd".
It doesn't use /etc/rc*.d/[KS]* symlinks to control services.  Instead,
you use commands to control it:

systemctl status gdm3
systemctl disable gdm3
systemctl stop gdm3

and so on, where "gdm3" is the name of the service that you want to
manage.  See "man systemctl" for some more details on that particular
command, or "man systemd" for a more general starting point.

There may even be some special magic required for display managers,
above and beyond the init system.  If systemctl disable doesn't work,
then report back and let us know which DM it is.  Maybe someone will
know the magic involved in disabling it.

... or you could just remove the package.  That will always work.
