I'm using a template that I can't/shouldn't modify. This template forces a font which is not the normal font of latex, how can I restaure the automatic font (I think which is Serif by default)
The template:
\documentclass[12pt, openany]{report}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[a4paper,left=2cm,right=2cm,top=2cm,bottom=2cm]{geometry}
\usepackage[english]{babel}
\usepackage{libertine}
\usepackage[pdftex]{graphicx}
\setlength{\parskip}{1ex plus 0.5ex minus 0.2ex}
\newcommand{\hsp}{\hspace{20pt}}
\newcommand{\HRule}{\rule{\linewidth}{0.5mm}}
\begin{document}

Another question of yours was also taggedbiblatexoriginally, even though it had nothing to do withbiblatex(biblatexis a bibliography package, neither do you load it, no is your question remotely about bibliographies). Please be a bit more careful with tagging in the future. – moewe Aug 25 '15 at 15:00\usepackage{lmodern}since its loadsT1font encoding. By the way, there is no ‘normal’ font in LaTeX. There is a default font (Computer Modern), that most people aren't able to change. It is as though you said Times is the normal font for a M* Office document. – Bernard Aug 25 '15 at 15:02tex/latex/base/*- only the switch. – cfr Aug 29 '15 at 01:20
