Hello Ernesto,
Could you send a LyX file that shows the problem?
Concerning the packages that get added to the preamble, I have a few
remarks:
These packages are already used by LyX as needed. You should not need
to specify them.
\usepackage{graphicx}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{babel}
This command is probably not useful, as amsmath provides the
equivalent \boldmath:
\usepackage{bm}
These packages may be useful but maybe only in some cases. They should
probably be used in the preamble of the document.
\usepackage{dcolumn}
\usepackage{url}
\NRCurl{url}
\usepackage{array}
This is probably useful:
\renewcommand{\topfraction}{.95}
\renewcommand{\textfraction}{.05}
\renewcommand{\floatpagefraction}{.95}
\numberby {equation}{section}
\setcounter{equation}{0}
These macros really look like something people _may_ want to use, but
that are not really required:
\newcommand{\PreserveBackslash}[1]{\let\temp=\\#1\let\\=\temp}
\let\PBS=\PreserveBackslash
\let\p=\phantom
\let\mc=\multicolumn
\newcommand\T{\rule{0pt}{2.6ex}}
\newcommand\B{\rule[-1.2ex]{0pt}{0pt}}
In general, I think nothing should be added to the preamble of the
layout file, but rather in the preamble of a template, so that people
can modify the code.
