One thing is that if you are running a server, superfluous messages like aboutX11 not being set can really [...]I don't fully understand if this is really the same issue, but I have an instance of Octave running in a CGI and creating a PNG plot. Even if Istart the plotting commands with figure("visible","off") I get warning: X11 DISPLAY environment variable not set in Apache's error log for each invocation of the CGI script. This happens even with Octave 3.2 rc4.
That warning is from Octave's src/display.cc, which determines the resolution (dpi) and size of the screen.
The warning is not triggered by using the graphics backend, but is part of the initialization process.
