I am preparing a poster presentation and due to historical reasons I am using beamerposter class for this. At some point I realized that the hyphenation in beamer is "switched off" because authors of the package know that there should be no hyphenation in the presentation. However, for the poster presentation, missing hyphenation looks ugly.
What is the correct way to use hyphenation with beamerposter? The solution from Hyphenation in Beamer Presentations works, but needs some extra work by fitting the formatting to other parts of the presentation.
MWE:
\documentclass[final,xcolor={cmyk}]{beamer}
\usepackage[english]{babel}
\usepackage{kantlipsum}
\usepackage[orientation=portrait,size=a0]{beamerposter}
\usepackage{ragged2e} % justify text
\begin{document}
\begin{frame}{}
\begin{columns}[t,onlytextwidth]
\begin{column}{.49\linewidth}
\begin{block}{Deafault Beamer behavior}
\kant[1-2]
\end{block}
\begin{block}{Hyphenation works here}\justifying\leftskip=4ex\rightskip=4ex
\kant[1-2]
\end{block}
\end{column}
\begin{column}{.49\linewidth}
\end{column}
\end{columns}
\end{frame}
\end{document}
Note that to make them look similar I need to change leftskip and rightskip to correct value which depends on the theme.
