PS:
I know this looks like a blog ;-)
You get the same result with the following document
#+BEGIN_SRC org
,#+STARTUP: beamer
,#+LATEX_COMPILER: lualatex
,#+OPTIONS: toc:nil
,#+LATEX_CLASS: ltx-talk
,#+LATEX_CLASS_OPTIONS:
,#+TITLE: Testing =ltx-talk=
,#+BEAMER_THEME:
* A frame
- First
- Second
- Third
,# Local variables:
,# org-latex-hyperref-template: nil
,# org-latex-packages-alist: nil
,# org-latex-default-packages-alist: nil
,# End:
#+END_SRC
if you add the following in your emacs config:
#+BEGIN_SRC emacs-lisp
(use-package ox-beamer
:ensure nil
:after org
:config
(add-to-list 'org-latex-classes '("ltx-talk" "\\DocumentMetaData{tagging
= on}
\\documentclass{ltx-talk}\n")))
#+END_SRC
But I don't know if that is enough or you really need to add \frametitle{}
or you can add the title after the frame.
Again, I'll need people interested in testing all this ;-)
