Beamer outline disappearing

Question

I'm using making my first set of Beamer slides for an upcoming presentation and noticed the outline on the top of the slides doesn't have the same coloring as that shown for the particular theme I'm using.

This image is what the outline looks at the beginning of the presentation and when I get to the section "Introduction" the highlight color changes to black, so it disappears.

The Warsaw theme though shows this going to a brighter white? Any idea on why this might be happening? I'm working in Lyx but exported to a .tex file to see if that might help, but nothing changed. I'm also on Ubuntu 18.04.

In attempting to create a MWE I found the following code is what causes the problem

\ifx\hypersetup\undefined \AtBeginDocument{% \hypersetup{unicode=true, bookmarks=true,bookmarksnumbered=true,bookmarksopen=false, breaklinks=false,pdfborder={0 0 1},backref=false,colorlinks=true,pdftitle={The LyX User's Guide}, pdfauthor={LyX Team}, pdfsubject={LyX}, pdfkeywords={LyX}, linkcolor=black, citecolor=black, urlcolor=blue, filecolor=blue, pdfpagelayout=OneColumn, pdfnewwindow=true, pdfstartview=XYZ, plainpages=false} } \else \hypersetup{unicode=true, bookmarks=true,bookmarksnumbered=true,bookmarksopen=false, breaklinks=false,pdfborder={0 0 1},backref=false,colorlinks=true,pdftitle={The LyX User's Guide}, pdfauthor={LyX Team}, pdfsubject={LyX}, pdfkeywords={LyX}, linkcolor=black, citecolor=black, urlcolor=blue, filecolor=blue, pdfpagelayout=OneColumn, pdfnewwindow=true, pdfstartview=XYZ, plainpages=false} \fi

This is being put in by Lyx. How do I change this?

Solution In Lyx under Document -> Settings -> PDF Properties if you uncheck the box Customize Hyperref Options, you'll get the correct output for your Beamer presentations.

Answer 1

Remove all this messing with the \hypersetup from your document. Beamer makes a lot of effort to set all colours suitable to the current theme and your new setup just throws away all these settings and makes the links black.

As a side effect you will also get more sensible pdf meta information which will contain the author and title of the presentation instead of these uninformative lyx stuff.

\documentclass{beamer}


\usetheme{Warsaw}

%\ifx\hypersetup\undefined
%  \AtBeginDocument{%
%    \hypersetup{unicode=true,
% bookmarks=true,bookmarksnumbered=true,bookmarksopen=false,
% breaklinks=false,pdfborder={0 0 1},backref=false,colorlinks=true,pdftitle={The LyX User's Guide},
% pdfauthor={LyX Team},
% pdfsubject={LyX},
% pdfkeywords={LyX},
% linkcolor=black, citecolor=black, urlcolor=blue, filecolor=blue, pdfpagelayout=OneColumn, pdfnewwindow=true, pdfstartview=XYZ, plainpages=false}
%  }
%\else
%  \hypersetup{unicode=true,
% bookmarks=true,bookmarksnumbered=true,bookmarksopen=false,
% breaklinks=false,pdfborder={0 0 1},backref=false,colorlinks=true,pdftitle={The LyX User's Guide},
% pdfauthor={LyX Team},
% pdfsubject={LyX},
% pdfkeywords={LyX},
% linkcolor=black, citecolor=black, urlcolor=blue, filecolor=blue, pdfpagelayout=OneColumn, pdfnewwindow=true, pdfstartview=XYZ, plainpages=false}
%\fi
