No, it's the other way round. With pdflatex, the page is rotated (as it should be), not with the other drivers, as long as you do not pass the correct driver (dvipdfm or dvips) as a package option to pdflscape.
Jürgen, LyX is installed here with pdflatex as the default driver, accessed via Ctrl-x h. What I need to learn is why the second page of the MWE does not rotate into landscape orientation using pdflatex (and neither do the three landscape oriented pages in the real document.) Where do I look for the reason? Thanks, Rich
