HelloYes 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

For testing purposes just move gdm out of the way, Just move /usr/bin/gdm to /
root, when everything is working fine, move it back.
So you have a good way to test and go to default later.
You can also try to force initlevel (I do not know, if this is still working
in debian), so it will not run into rc5 (with X) but to rc2 (no X). I guess,
there are people who know better than me, which runlevel is without X.
I did this 10 years ago and forgot about it.
Hope this helps
