It=E2=80=99s a common misconception that I shared years ago =E2=80=94 =
but GNUstep is not really a full environment. It really is a set of =
libraries that let you write Objective-C apps =E2=80=94 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 =E2=80=9Ca GNUstep environment=E2=80=9D =E2=80=94 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=E2=80=99t 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=E2=80=99=
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=E2=80=99d =
expect that the advice you read was trying to make you do this.)

Now, the error you=E2=80=99re getting means that your OS is not actually =
running GDM as the login manager or that it even has it installed. Given =
it=E2=80=99s Ubuntu, I=E2=80=99d expect that it=E2=80=99s 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 =E2=80=94 this doesn=E2=80=99t mean you=E2=80=99ll 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=E2=80=99s =
easy to start it back up, as long as there=E2=80=99s 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=E2=80=99s SystemPreferences to switch from NeXT-like theme to =
the GTK theme. (Assuming it=E2=80=99s installed.)

To avoid confusion with numerous other =E2=80=9Csystem=E2=80=9D =
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=E2=80=99s =
installed =E2=80=94 do note that UNIX is case sensitive. You=E2=80=99ll =
get the right one because nearly nobody else but GNUstep uses upper-case =
characters in app binary names. :-)

Good luck!=
