No, it just means that the OpenGL engine can't find a matching GL visual
for that Xserver visual. It's a warning, nothing fatal.

I remember it has an oprtion to set the resolution via command line (like Mozilla now as a GUI item for resolution/quality in the print options dialog) but I do not remember the details.

See "xphelloworld" usage:
-- snip --
% xphelloworld -h
usage:  ./xphelloworld [options]
-printer printernname   printer to use
-printargs args [ arg=value , ... ]
        args:   tofile=<filename>
                papersize=<paper name>
                orientation=<orientation>
                resolution=<DPI>
                plex=<plex>
                title=<string>

Maybe Paul can clarify that situation a little bit (CC:'ing him for
that) ...
