I try to change my main font style in a Tufte book document class. Documentation say that it's possible by using the nofonts class option but nothing works. I tried the \setmainfont function, and other tricky solutions, without result. Here are my packages:
\documentclass[11pt, justified]{tufte-handout}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{graphicx}
\setkeys{Gin}{width=\linewidth,totalheight=\textheight,keepaspectratio}
\graphicspath{{graphics/}}
\usepackage{lmodern}
\usepackage{amsmath, amssymb, amsfonts, euscript}
\usepackage{mathabx, mathrsfs, mathptmx}
\usepackage{booktabs}
\usepackage{units}
\usepackage{multicol}
\usepackage{lipsum}
\usepackage{fancyvrb}
\fvset{fontsize=\normalsize}
\usepackage[frenchb]{babel}
\usepackage{titlesec}
\usepackage{bibentry}
\usepackage{xcolor}
\usepackage{enumerate}
\usepackage{enumitem}
\usepackage{microtype}
\usepackage{todonotes}
\usepackage{fontawesome}
\usepackage{listings}
\usepackage{geometry}
\usepackage{theorem}
\usepackage{fancyhdr}
\usepackage[most]{tcolorbox}
\usepackage[framemethod=TikZ]{mdframed}
\usepackage{ifthen}
\usepackage{tikz}
\usetikzlibrary{shadows}
\lstset{language=C}
Thanks for your help.

Best Answer
The problem with your code was, that you were overriding any font settings in the preamble by explicitly selecting fonts with commands like
\renewcommand{\rmdefault}{pplx}.After removing all the explicit font selections
and several other things that dindn't spark joyfrom your code you can now use a font of your choosing. I tried the Linux Libertine and Biolinum Fonts with\usepackage{libertine}:pdffontsshows, that no other fonts were loaded:
