Hello, I would like to report that inserting a list of listings creates errors with book document classes.
Environment: I compiled LyX 2.4.2.1 on Ubuntu 22.04 with Qt6 enabled. Steps to reproduce: 1. Create a new document: File > New 2. Set the document class to one of the book classes, for example Koma-Script Book 3. Insert a list of listings: Insert > List/Contents/References > List of Listings 4. Try to compile the PDF document: Document > View [PDF (pdflatex)] Expected result: The document is compiled successfully. Actual result: Various errors depending on the document class. Additional information: This is the LaTeX code typically generated by LyX when adding a list of listings: \documentclass{scrbook} \usepackage[T1]{fontenc} \usepackage[utf8]{inputenc} \usepackage{listings} \renewcommand{\lstlistlistingname}{\inputencoding{latin9}Listings} \begin{document} \lstlistoflistings{} \end{document} Adding the following ERT at the beginnig of the document prevents errors : \renewcommand{\lstlistlistingname}{Listings} I suspect the errors are happening because LyX automatically add a line in the preamble that contains \inputencoding{latin9} -- lyx-devel mailing list lyx-devel@lists.lyx.org http://lists.lyx.org/mailman/listinfo/lyx-devel
