Linux xelatex and type1 font

[syvshc]

Description

I'm an Arch Linux user, when I want to use \setmainfont{Libertinus Serif} to set main font. I straightly met an xdvipdfmx's error:

xdvipdfmx:fatal: Invalid font: -1 (0)

This will not happen on my Windows pc.

I also post it at tex.se: https://tex.stackexchange.com/questions/612718/using-other-fonts-caused-xdvipdfmxfatal-invalid-font-1

And I refered to https://github.com/wspr/fontspec/issues/419 but I didn't find useful information.

Check/indicate

• [x] Relevant for XeTeX
• [ ] Relevant for LuaTeX
• [x] Issue tracker has been searched for similar issues?
• [x] Links to <tex.stackexchange.com> discussion if appropriate

Minimal example demonstrating the issue

\documentclass{article}
\usepackage{fontspec}
\setmainfont{Libertinus Serif}
\begin{document}
    Here are some lines to read. 
\end{document}

Further details

I read https://github.com/wspr/fontspec/issues/419 again.

fontspec does not have anything to do with font lookup, it just uses whatever the engine provides.

It means that the xetex engine choose the type1 version font, not fontspec. So maybe I should ask xdvipdfmx that "Why xdvipdfmx can't deal with 'type1' font on linux?"

I would guess that you configured fontconfig to look for type1 fonts, see
