It seems like there is no "force" flag for the Greek letters in
"unicodesymbols". This means that Greek Unicode-chars are kept as-is

* This is good for the pdfstring

  http://milde.users.sourceforge.net/LGR/).

Thank you so much Guenter! I've copied over "lgrxenc.def" [1],   
"lgrenc.dfu" [2] and "textgreek.sty" [3] to the local  
"/usr/share/texmf-texlive/tex/latex/base/" directory, ran "sudo  
texhash afterwords" and went ahead to run pure LaTeX code (through  
TeXmaker):

The "expanded" minimal working example looks like:

--%<---
\documentclass[greek,english]{scrbook}
\usepackage[LGRx,T1]{fontenc} % define LGR and T1 encodings
\usepackage[utf8]{inputenc} % standard UTF-8 input encoding
\usepackage[greek,english]{babel}
\usepackage[unicode]{hyperref}
\usepackage{bookmark}

Full success :-) Yet, within LyX the sigma(s) come out as either "c"  
or "sv" out(?)!
