OK, now I see the rationale: tufte-book loads geometry by default, so geometry options are easy to clash if we set them directly in LyX.
Instead of disabling geometry in LyX document settings, is it possible to disable \usepackage{geometry} in the source in the case of Provides geometry 1 ? I mean only add \geometry{paperwidth=...}. Otherwise we have to add the TeX code to the preamble manually. Thanks!
