It’s a common misconception that I shared years ago — but GNUstep is not really
a full environment. It really is a set of libraries that let you write
Objective-C apps — not an environment as such. Think GTK and glib, not GNOME;
or think Qt, not KDE.
Individual users (some core devs among them) often set up something that looks
like “a GNUstep environment” — but the project really ships nothing of the sort
at this time.
Efforts are often underway outside the core project to provide such an
environment; for instance, currently NEXTSPACE
(https://github.com/trunkmaster/nextspace
<https://github.com/trunkmaster/nextspace>) is under development. I don’t think
it ships in any of the distributions at this time.
Easiest way to get something that could be seen as a GNUstep environment is to
pick the WindowMaker session in your login manager, then start things like the
gWorkspace.app, Recycler.app, etc.

(Note: Given you mentioned you are running Ubuntu 16.04, I think I’m safe in
assuming you are running an X11-based environment, and not Wayland based
environment.)
GDM is your login manager. These days, login managers run the X11 server for
you, and let you sign in.
When people recommend you stop GDM, they effectively tell you to stop the X11
server and end any running sessions more than anything else. (They may actually
want you to reload GDM configuration, but I’d expect that the advice you read
was trying to make you do this.)
Now, the error you’re getting means that your OS is not actually running GDM as
the login manager or that it even has it installed. Given it’s Ubuntu, I’d
expect that it’s running lightdm instead. Now, do keep in mind, if you stop
lightdm, just like with GDM and other login managers, you /will/ end up
terminating your graphical session — this doesn’t mean you’ll be able to see
GNUstep without GNOME, but that you will be signed out *and* dropped to a fully
text based environment. (This is the only thing that can happen, given that you
will terminate the X server. It’s easy to start it back up, as long as there’s
no bugs and you can actually see the text display. But, be warned.)
What you instead want to do is install WindowMaker, and, when asked for
username and password by lightdm, choose WindowMaker.
WindowMaker is not part of GNUstep, but it has the appropriate look&feel.
Alternatively, you may want to run under GNOME or Unity, but use GNUstep’s
SystemPreferences to switch from NeXT-like theme to the GTK theme. (Assuming
it’s installed.)
To avoid confusion with numerous other “system” configuration utilities that
may be installed on your system, instead of using the launcher menu, you can
literally type this into terminal to launch GNUstep's globally-installed
SystemPreferences, if it’s installed — do note that UNIX is case sensitive.
You’ll get the right one because nearly nobody else but GNUstep uses upper-case
characters in app binary names. :-)
Good luck!
