There are two things to do about this:
1) it is possible to define your own command for translation between LaTeX
and dvi/pdf (Edit/Preferences/Converters) which will be your own shell
script removing from .tex file offending lines (it is called vlnlatex and
there is a link to it called pdfvlnlatex -- if you want to call it
otherwise you have to fix line 5):
#!/bin/sh
LATEX='latex'
ZAKLAD=$(basename $1 .tex)
if [[ $(basename $0) == "pdfvlnlatex" ]]
then
PROG="pdf$LATEX"
else
PROG=$LATEX
fi
if ( grep -q '^\\documentclass.*{manual}' $ZAKLAD.tex )
then
# assuming GNU sed
sed -e '/\\IfFileExists{url.sty}/,+1d' \
< $ZAKLAD.tex > $ZAKLAD.ptex
else
cp $ZAKLAD.tex $ZAKLAD.ptex
fi
$PROG $ZAKLAD.ptex
Of course, the alternative option would be to ask developers (i.e., to file
a wish) to allow us to edit WHOLE preamble (at least in layout files),
because the current situation when LyX puts into .tex file some commands
and _user has no way how to influence it_ is insane.
