Hello Yes I agree with Hans, you can change the default runlevel to 2 which gives you a terminal then when you are ready, run gdm3 (starts X automatically) or 'sudo init 5' to load the default window manager.
Do some research into init runlevels and I think it will help you a great deal with a lot of things. Regards Am Mittwoch, 3. Mai 2017 schrieb Hans : > Am Mittwoch, 3.
