# How to change the footer of madrid theme in latex

I am using madrid theme in beamer using following code,

\documentclass{beamer}

\usecolortheme{beaver}
\usepackage{utopia}
\usepackage[normalem]{ulem}
\usepackage{graphicx}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage[utf8]{inputenc}
\usepackage{mathtools}
\usepackage{multicol}

\usefonttheme{professionalfonts}

\title[Title]{Title}
%\author{M. Saiful Bari\inst{1} \and Mr X\inst{2}}
\author{My Name\inst{1}}
\institute{
\inst{1}
Sample University testing and testing
}

\date{20 June, 2017}

\begin{document}

\frame{\titlepage}

\section{test}

\end{document}


The following output is generated,

Here see that my "Name and Institution" at the footer is cut down. How to extend more position for "Name and Institution". I have seen many post regarding the customization. I am new to latex. Please provide comment while writing code so that I can customize the theme by myself.

• Untested: Try \author[Short Version]{Long Version}. Short Version goes into the footer. – Dr. Manuel Kuehner Aug 19 '17 at 11:05

Basically the same as How to modify the margin in the footline of beamer?

Adjust the width of the three beamercolorboxes by modifying wd=.4\paperwidth, you just have to make sure that the sum of the widths still adds up to 1.

--

• you don't need graphicx, as beamer already provides this functionality
• I don't see any justification to use multicol in beamer, as beamer has it's own environment for columns.
• if you look into your log file you will see that utopia gives the message This package is to be regarded as obsolete.
