For jessie/systemd,

# systemctl set-default multi-user.target

and, to revert,

# systemctl set-default graphical.target

you don't want a DE (like me).

There are several recent threads in this list about getting the
right video drivers and X servers installed. Most of it goes
over my head because my hardware is so old.
