It is unclear to me, from what you say, whether this problem arose
after the upgrade to stretch, or was also a problem in jessie, before
the upgrade.

Not me. Maybe somebody smart will chime in.

But until they do, I'll tell you 3 things I might try.


Thing 1:

There is some information of interest in the "Virtual Terminals"
section of this discussion:

  http://0pointer.de/blog/projects/serial-console.html

The last paragraph of that section says:

| Secondly, tty6 is especially reserved for auto-spawned gettys and
| unavailable to other subsystems such as X. This is done in order to

So you might check whether tty6, in particular, is available. Do
Ctrl-Alt-F6, and see if you get a login prompt.


Thing 2:

If that doesn't work, I wonder what files you see in
/etc/systemd/system/getty.target.wants/ ?

  $ ls /etc/systemd/system/getty.target.wants

You could ask systemd to, from now on, prepare some more VTs at boot
by soft-linking lib/systemd/system/getty@.service into that directory.

As root, to arrange for a VT on tty2, you could do...

  # DESTDIR=/etc/systemd/system/getty.target.wants
  # ln -s /lib/systemd/system/getty\@.service $DESTDIR/getty\@tty2.service

...and so on, for tty3, tty4, etc...

  # ln -s /lib/systemd/system/getty\@.service $DESTDIR/getty\@tty3.service
  # ln -s /lib/systemd/system/getty\@.service $DESTDIR/getty\@tty4.service


Thing 3:

If you don't want to wait for reboot, don't feel like making big plans
for the future, and just want a VT now, as root do something like

  # systemctl enable getty@tty8.service
  # systemctl start getty@tty8.service

and then Ctrl-Alt-F8.

Hope this helps.
