Ok, but the book I am reading mentions X.org and how XFree86 was some kind of part of the X.org organization (if I got it right at all). The confusion for me was if there is a difference between X.org and the xorg.conf-file on my system.
Btw, the book mentioned the tougher licenses but in a more complex way then you mentioned it, sometimes I don't understand way people have to make some things so hard. But thanks anyway.
