[Tex/LaTex] Making Verbatim and Beamer play nice

beamerverbatim

I'm writing a beamer presentation on basic math type-setting in latex and I've been trying to use verbatim to display how math equations are typed. Using fragile this works, but I still get several annoying error messages every time I compile, so I'm never sure if I have an actual error or if beamer is just complaining about verbatim. The current offender would be:

\begin{verbatim}
\[
  X := \bigcup_{n \in \Mb N}\coprod_{\lambda \in \Lambda} 
       (X_\lambda \cap Y_\lambda ) \vee \Mb S^{n}.
\]
\end{verbatim}

I get error messages along the lines of:

LaTeX Font Warning: Font shape `OT1/cmss/m/n' in size <4> not available
(Font)              size <5> substituted on input line 11.

l.10   \end{verbatim}

Are there any workarounds for this, something I can change in the code to make these error messages go away?

It seems that you use this hack of mine. (I told you that I wouldn't suggest using it, but I feel honored that you like it ...) However, as I wrote there, the hack is designed for the CM fonts only, so you shouldn't use it with the standard beamer fonts.

That said, I can't reproduce the error. I used the code Stefan Kottwitz had in the first version of his answer, and added my hack in the preamble. This compiles nicely.

Herbert's answer was helpful! However, for the sake of completeness, here's the correction of the second part of my code from the question:

\begin{minipage}{0.85\linewidth}
   \begin{semiverbatim}\small
       \uncover<1->{\\begin\{tikzpicture\} }
       \uncover<1->{  \alert<1>{\\draw [step=.2cm,gray!50,thin] (-1.5,-1.5) 
                      grid (1.5,1.5);}}
       \uncover<2->{  \alert<2>{\\draw (-1.5,0) -- (1.5,0);} }
       \uncover<3->{  \alert<3>{\\draw (0,-1.5) -- (0,1.5);}}
       \uncover<4->{  \alert<4>{\\draw[red,line width=2pt] (0,0) circle (.8cm);}}
       \uncover<5->{  \alert<5>{\\draw[green,line width=2pt] (-1,-1) 
                      rectangle (1,1);}}
       \uncover<6->{  \alert<6>{\\draw[blue,line width=2pt] (-.5,-.5) 
                      parabola (1,1);}}
       \uncover<1->{\\end\{tikzpicture\}}
   \end{semiverbatim}
\end{minipage}

Thanks you all!

[Tex/LaTex] Author and institute don’t appear when adding background image to title page in beamer

If all you want to do is to add an image in the background for the title page, the method described in the linked answer is not the most appropriate one, since setting the title page template demands setting all the elements of the template and their attributes (which is part of your problem (see below)).

A more convenient approach is to locally (inside a group) set the background canvas template:

\documentclass{beamer}

\setbeamercolor{background canvas}{bg=black}
\setbeamercolor{normal text}{fg=white}
\setbeamercolor{title}{fg=white}

\title{The title}
\author{The Author}
\institute{The Institute}

\begin{document}

\begingroup
\setbeamertemplate{background canvas}{%
\includegraphics[width=\paperwidth,height=\paperheight]{mushrooms}}
\begin{frame}
\maketitle
\end{frame}
\endgroup

\begin{frame}
test
\end{frame}

\end{document}

If you, however, want to completely change the title page template by setting the template from scratch, then:

Your title is not centered because your current settings don't tell LaTeX that you want it centered; in fact, the minipage you are using for the title is way too big, as you can see by temporarily disabling the colors and framing it:

\documentclass{beamer}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{libertine} % or any other font package (or none)
\newcommand*\quotefont{\fontfamily{LinuxLibertineT-TLF}} % selects Libertine for quote font
\usepackage{tikz}
\usefonttheme[onlylarge]{structurebold}
\setbeamerfont*{frametitle}{size=\normalsize,series=\bfseries}
\setbeamertemplate{navigation symbols}{}

%\setbeamercolor{background canvas}{bg=black}
%\setbeamercolor{normal text}{fg=white}

\pgfdeclareimage[width=\paperwidth]{mybackground}{bigdata410}

\setbeamertemplate{title page}{   
        \begin{picture}(0,0) 
            \put(-30,-163){%
    %            \pgfuseimage{mybackground}
            } 
            \put(0,-110.7){%
            \centering
                \frame{\begin{minipage}[b][45mm][t]{226mm}
                \centering
                    \usebeamerfont{title}{\inserttitle\par}
                \end{minipage}}
            }  
            \end{picture}
    } 
\title{Lost in data}
\author[Author et al.\@]{Author}
\institute{University of }
\date{}

\begin{document}

\begin{frame}
  \titlepage
\end{frame}
\end{document}

enter image description here

Change 226mm to \textwidth and use \centering inside the minipage:

\documentclass{beamer}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{libertine} % or any other font package (or none)
\newcommand*\quotefont{\fontfamily{LinuxLibertineT-TLF}} % selects Libertine for quote font
\usepackage{tikz}
\usefonttheme[onlylarge]{structurebold}
\setbeamerfont*{frametitle}{size=\normalsize,series=\bfseries}
\setbeamertemplate{navigation symbols}{}

%\setbeamercolor{background canvas}{bg=black}
%\setbeamercolor{normal text}{fg=white}

\pgfdeclareimage[width=\paperwidth]{mybackground}{bigdata410}

\setbeamertemplate{title page}{   
        \begin{picture}(0,0) 
            \put(-30,-163){%
    %            \pgfuseimage{mybackground}
            } 
            \put(0,-110.7){%
                \frame{\begin{minipage}[b][45mm][t]{\textwidth}
                    \centering
                    \usebeamerfont{title}{\inserttitle\par}
                \end{minipage}}
            }  
            \end{picture}
    } 
\title{Lost in data}
\author[Author et al.\@]{Author}
\institute{University of }
\date{}

\begin{document}

\begin{frame}
  \titlepage
\end{frame}

\end{document}

Perhaps you also want to reduce the height?

There's no title nor institution since your settings for the title page template don't have the corresponding inserts; where do you want this information to appear? Use \insertauthor, \insertinstitution at the desired locations. For example:

\documentclass{beamer}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{libertine} % or any other font package (or none)
\newcommand*\quotefont{\fontfamily{LinuxLibertineT-TLF}} % selects Libertine for quote font
\usepackage{tikz}
\usefonttheme[onlylarge]{structurebold}
\setbeamerfont*{frametitle}{size=\normalsize,series=\bfseries}
\setbeamertemplate{navigation symbols}{}

\setbeamercolor{background canvas}{bg=black}
\setbeamercolor{normal text}{fg=white}

\pgfdeclareimage[width=\paperwidth]{mybackground}{bigdata410}

\setbeamertemplate{title page}{   
        \begin{picture}(0,0) 
            \put(-30,-163){%
                \pgfuseimage{mybackground}
            } 
            \put(0,-110.7){%
                \frame{\begin{minipage}[b][45mm][t]{\textwidth}
                    \centering
                    \usebeamerfont{title}{\inserttitle\par}\vfill
                    \usebeamerfont{author}{\insertauthor\par}\vfill
                    \usebeamerfont{institute}{\insertinstitute\par}
                \end{minipage}}
            }  
            \end{picture}
    } 
\title{Lost in data}
\author[Author et al.\@]{Author}
\institute{University of }
\date{}

\begin{document}

\begin{frame}
  \titlepage
\end{frame}

\end{document}

enter image description here

Once you are happy with the settings, delete (or comment out) the \frame command:

\documentclass{beamer}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{libertine} % or any other font package (or none)
\newcommand*\quotefont{\fontfamily{LinuxLibertineT-TLF}} % selects Libertine for quote font
\usepackage{tikz}
\usefonttheme[onlylarge]{structurebold}
\setbeamerfont*{frametitle}{size=\normalsize,series=\bfseries}
\setbeamertemplate{navigation symbols}{}

\setbeamercolor{background canvas}{bg=black}
\setbeamercolor{normal text}{fg=white}

\pgfdeclareimage[width=\paperwidth]{mybackground}{bigdata410}

\setbeamertemplate{title page}{   
        \begin{picture}(0,0) 
            \put(-30,-163){%
                \pgfuseimage{mybackground}
            } 
            \put(0,-110.7){%
                \begin{minipage}[b][45mm][t]{\textwidth}
                    \centering
                    \usebeamerfont{title}{\inserttitle\par}\vfill
                    \usebeamerfont{author}{\insertauthor\par}\vfill
                    \usebeamerfont{institute}{\insertinstitute\par}
                \end{minipage}%
            }  
            \end{picture}
    } 
\title{Lost in data}
\author[Author et al.\@]{Author}
\institute{University of }
\date{}

\begin{document}

\begin{frame}
  \titlepage
\end{frame}

\end{document}

There are several ways to remedy this warning; load a font containing the missing font size (lmodern, for example) or use \let\Tiny\tiny.
