this is propably an Ubuntu packaging error; but just to confirm...


... this works on your texlive (2009) distribution with pdflatex?

I get Undefined control sequence. on the noun command. Hmm

Where have you got this from? \noun is not a standard LaTeX macro. – Joseph Wright Sep 28 '11 at 12:43
I use TeX Live 2009 in Ubuntu and I also get Undefined control sequence for \noun. – N.N. Sep 28 '11 at 12:43

This can't work on any TeX distribution, since the neither the LaTeX kernel nor the article class define a command called \noun.

If you used it in the past, it probably was from some package (I don't remember having seen it, though) or defined in the preamble of the document.

In order to write text inside math formulas, load the amsmath package and use \text.

Thanks for your answers, I just found out \noun is LyX-specific: \newcommand{\noun}[1]{\textsc{#1}} So I was really looking for \textsc :-) – eisbaw Sep 28 '11 at 13:20
