Xelatex or Lualatex vs. utf8 inputenc
look for “document convertion” in the ubuntu desktop guide and install those few packages.
here’s a MWE with no feature what-so-ever
vi no-feature.tex
\documentclass[a4paper]{article}
\begin{document}
\title{some title}
\author{some author}
\maketitle
some text
\end{document}
the geometry package is implicit as the a4paper option gets passed to it.
build the document
xelatex no-feature.tex # create aux xelatex no-feature.tex evince no-feature.pdf &
and in case you got bib, do that before
xelatex codeblock.tex biber codeblock.tex
the last defined language becomes the default (here english)
\usepackage[russian,english]{babel}
% ngerman frenchb
\usepackage[labelformat=empty]{caption}
\usepackage[cm]{fullpage}
\usepackage{url}
% remove section numbers and keep the toc
\renewcommand{\thesection}{}
\renewcommand{\thesubsection}{}
\renewcommand{\thesubsubsection}{}
here’s a MWE with a table of content
xelatex toc.tex # create aux xelatex toc.tex evince toc.pdf &
\usepackage{fontspec}
\setmainfont{FreeSerif}
\setsansfont{FreeSans}
\setmonofont{FreeMono}
