I have found a lot of question about Xorg not starting by default, but this is actually what I want.
How can I have Linux Mint (17 Quiana) not start GUI, just the shell (I believe that is supposed to be login shell)?
The following should switch of
mdm startup at boot for
echo manual | sudo tee /etc/init/mdm.override
Just remove the
.override file if you want the service to start normal.
You can start the service from the console with
sudo service mdm start
