I copied the layout file under /usr/share/lyx/layouts and executed "Reconfigure". I can't see the new class. Any hints?
You will see in the console when LyX is reconfigured, if LyX could find the LaTeX-class "achemso". I guess that you haven't correctly installed the LaTeX-package "achemso" to your LaTeX distribution. (Daniel replied me that it works for him.)
