libertine + beramono + LuaLaTeX incompatible

Question

Consider the following code:

\documentclass{article}

\usepackage[T1]{fontenc}
\usepackage{libertine}
\usepackage{beramono}

\begin{document}
This is some regular text

\texttt{This is some monospace text}
\end{document}

If I compile this with pdflatex then the result is as expected: the regular text is in the Libertine font, and the monospace text is in the Bera Mono font.

If I compile this with lualatex then the monospace text is in the default (Computer Modern?) font. I expected it to be the same as pdflatex's output.

I have tried passing [mono=false] option to the libertine package, but it makes no difference.

How do I fix this?

Answer 1

If you are happy to switch to lualatex then you probably should use fontspec explicitly. I've installed Bitstream Vera and Libertine on my Mac, and this is how I would use them to get the combination the OP wants:

\documentclass{article}

% \usepackage[T1]{fontenc}
% \usepackage{libertine}
% \usepackage{beramono}

\usepackage{fontspec}
\setmainfont{Linux Libertine O}
\setsansfont{Bitstream Vera Sans}[Scale=MatchLowercase]
\setmonofont{Bitstream Vera Sans Mono}[Scale=MatchLowercase]

\begin{document}
This is some regular text.  \textsf{Sans text}.

\texttt{This is some monospace text}
\end{document}

The names I have used for the fonts are the names that appear in FontBook.app after I have installed them. The Scale parameter helps to make the families look consistent.

Compiling the example above with lualatex produces this:
