Two ways:

A)

1) log into gnome and go to system settings > Display and turn it off that way.
2) then copy ~/.config/monitors.xml to /var/lib/gdm/.config as root

B)

1) Edit /etc/default/grub so that GRUB_CMDLINE_LINUX has

video=VGA1:d

in it

then run

grub2-mkconfig -o /boot/grub2/grub2.cfg

(as root)
