Ignoring page numbers in backup slides

I am using the beamer document class in latex to make a presentation. I will have a number of back up slides which are there for offline viewing, reference etc. Beamer has a feature that shows the progress through the presentation as {page#}/{total pages} on each slide. I would really like it if {total pages} was equivalent to my total number of pages w/out counting the back up slides (I don't want to discourage my audience on the first page!). Does anyone know how this can be done?

This can now be achieved with the following option on all "backup" slides:

\begin{frame}[noframenumbering]{My Title}
\end{frame}

Source

This will cause the final number (e.g. 25/25) to be displayed on such pages.

As always, a matter of taste.

I have defined two commands to do this:

\newcommand{\beginbackup}{
   \newcounter{framenumbervorappendix}
   \setcounter{framenumbervorappendix}{\value{framenumber}}
}
\newcommand{\backupend}{
   \addtocounter{framenumbervorappendix}{-\value{framenumber}}
   \addtocounter{framenumber}{\value{framenumbervorappendix}} 
}

You can then use \beginbackup and \backupend before and after your backup slide to adjust the number of slides.

For my beamer template I also like to add

\setbeamertemplate{footline}{
  \leavevmode%
  \hbox{%
  \begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,center]{author in head/foot}%
    \usebeamerfont{author in head/foot}\insertshortauthor~~(\insertshortinstitute)
  \end{beamercolorbox}%
  \begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,center]{title in head/foot}%
    \usebeamerfont{title in head/foot}\insertshorttitle
  \end{beamercolorbox}%
  \begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,right]{date in head/foot}%
    \usebeamerfont{date in head/foot}\insertshortdate{}\hspace*{2em}
    \insertframenumber{} \hspace*{2ex} % hier hat's sich geändert
  \end{beamercolorbox}}%
  \vskip0pt%
}

in the definition of the \beginbackup command to hide to total page number in the backup slides, otherwise you'll get something like "24/18".

Using all this, your slides will be numbered like "x/Y" for all slides before the backup, where Y is the total number of slides before the first backup slide, and the backup slides will continue the numbering of the previous slides.

Partha

This can be done with the appendixnumberbeamer package. Just add \usepackage{appendixnumberbeamer} to the preamble and use \appendix before the first backup slide.

To manually fix the total frame count to a certain number, say 25, you could add the following command

\renewcommand{\inserttotalframenumber}{25}

right after the \begin{document} command.

You can also add the \appendix command right before the beginning of your backup slides, so that the corresponding sections/subsections do not appear in the table of contents/navigation structure.

It should be possible to tweak the renewcommand above so that it automatically uses the last frame number before the appendix, but I don't know how to do it.

Just insert

\renewcommand{\inserttotalframenumber}{\pageref{lastslide}}

after \begin{document}, and place the marker

\label{lastslide}

on your last slide.

Fanfan, thanks for your answer, your answer steered me to this sty file that one can include in a beamer document class that will automatically count only the number of frames before the appendix, and then restart the a separate count for the appendix slides, pretty neat.

Thanks also to Jérôme LELONG for having this available online.

You can put all of your backup slides in appendix and use the appendixnumberbeamer package.

\documentclass[12pt]{beamer}
\usepackage{appendixnumberbeamer}
\begin{document}
\begin{frame}{Frames that counts}
\end{frame}
\appendix
\begin{frame}{Backup slides}
\end{frame}
\end{document}

The great command \insertpresentationendpage will take care of your problem. Just place \appendix at the begin of your backup slides.

\documentclass[t]{beamer}

\usepackage[absolute,overlay]{textpos}
\setbeamertemplate{navigation symbols}{}

\def\insertpresentationendframe{\inserttotalframenumber}
\makeatletter
\g@addto@macro{\appendix}{\immediate\write\@auxout{\string\@writefile{nav}{\noexpand\headcommand{\noexpand\def\noexpand\insertpresentationendframe{\the\c@framenumber}}}}}
\makeatother

\setbeamertemplate{footline}{%
    \begin{picture}(54,12.5)(0,0)
    \put(0.9,0.52){%
        \begin{minipage}[b][12.5mm][c]{112.5mm}
        \raggedleft
        \insertframenumber/\insertpresentationendframe
        \end{minipage}
    }
    \end{picture}
}

\begin{document}

    \begin{frame}
        slide in the main part
        \only<2>{blub}
    \end{frame}

    \appendix
    \section*{Backup}

    \begin{frame}
        \frametitle{backup}
        not counting in the total frame number
    \end{frame}

\end{document}

Another possibility - which was recently added to beamer - is to use the appendixframenumber template:

\documentclass[t]{beamer}

\setbeamertemplate{footline}{
  \hfill%
  \usebeamercolor[fg]{page number in head/foot}%
  \usebeamerfont{page number in head/foot}%
  \setbeamertemplate{page number in head/foot}[appendixframenumber]%
  \usebeamertemplate*{page number in head/foot}\kern1em\vskip2pt%
}

\begin{document}

    \begin{frame}
        slide in the main part
        \only<2>{blub}
    \end{frame}

    \appendix
    \section*{Backup}

    \begin{frame}
        \frametitle{backup}
        not counting in the total frame number
    \end{frame}

\end{document}
