# textblock and \setbeameroption{show notes on second screen}

Anonymous created an issue

Hi,

I may have found a bug when using textblock and \setbeameroption{show notes on second screen}

== Normal case == Here is a simple example : two frames. There is a textblock on the second.

{{{ \documentclass{beamer} \usepackage[latin1]{inputenc} \usepackage[absolute,overlay]{textpos}

\begin{document}

\begin{frame}
Frame 1
\end{frame}

\begin{frame}
Frame 2
\begin{textblock}{5}[0,0](5,5)
Mon textblock
\end{textblock}
\end{frame}


\end{document} }}}

Here every thing is okay. The textblock appears on the second slide.

== The bug ==

Then, I want to display the notes with \setbeameroption{show notes on second screen} {{{ \documentclass{beamer} \usepackage[latin1]{inputenc} \usepackage[absolute,overlay]{textpos}

\usepackage{pgfpages} \setbeameroption{show notes on second screen=right}

\begin{document}

\begin{frame}
Frame 1
\end{frame}

\begin{frame}
Frame 2
\begin{textblock}{5}[0,0](5,5)
Mon textblock
\end{textblock}
\end{frame}


\end{document} }}}

MikTex 2.7

I didn't explained the result...

When I use \setbeameroption{show notes on second screen=right}, the textblock appears on the first slide instead of on the second slide.

Bump!

Indeed. It seems that beamer and textpos don't work very well together in dual-screen mode. I will look into it after the first release.

Oops! Sorry for this double post, and for the "Bump!" (I didn't know the effect on this button...)

Thank you rivanvx.

The problem seems to to be related to dual-screen mode in particular, but to any transformations performed by pgfpages (scaling, nup, whatsoever), which internally is used by a lot of beamer features. Apparently, pgfpages transformations just have no effect on the content inserted by textpos. Both perform their manipulations at shipout-time, which probably is the reason for the troubles.

Unfortunately, I have not yet found another way to put stuff to absolute coordinates on beamer slides. (I have tried with TiKZ "current page" node, which works fine in text documents, but with beamer slides the result wasn't really absolute positioning.)

2. This is ultimately due to the same cause as #176, which is really about how PDFs work. (I realise this may be non-obvious, but that is my take.)
