"LyX is an advanced open source document processor running on many Unix
platforms. It is called a "document processor", because unlike standard
word processors, LyX encourages an approach to writing based on the
structure of your documents, not their appearance. LyX lets you concentrate
on writing, leaving details of visual layout to the software. LyX automates
formatting according to predefined rule sets, yielding consistency
throughout even the most complex documents. LyX produces high quality,
professional output -- using LaTeX, an open source, industrial strength
typesetting engine, in the background.

Special thanks should go to Matthias Ettrich who started it all."

"After I founded the [KDE] project, I was busy with the stuff nobody else
wanted to do, like the terminal emulation, the window manager, the desktop
panel, session management..... Luckily these things changed while the
project evolved. Currently I'm mostly working on the libraries (DCOP), the
new window manager kwin and on improving Qt according to the wishes of the
KDE Team."

Thanks, that was the hint I needed.  Mathematica is expecting the Xrdb to be
initialized by XDM, but XDM isn't running.  If I initialize it with a call
to xrdb in the Mathematica startup script, it works with an
empty .Xdefaults, and no   /usr/X11R6/lib/X11/app-defaults/XMathematica
file.  

I'm really not sure what changed from the previous configuration because I
was not explicitly calling xrdb in my bin/mma, which I now do.

Now, back to creating structured documents using Mathematica with XML...
