I am running an Arch Linux / Windows 7 dual boot laptop.
The windows partition is mounted under arch and i made the windows fonts usable with ln -s /windows/Windows/fonts/ /usr/share/fonts/WindowsFonts
This works, every program besides luaLaTeX with fontspec has acces to the fonts, e.g. libreoffice.
But i am not able to use the fonts with:
\usepackage{fontspec}
\setmaintfont{Comic Sans MS}
The result is the font-not-found message from fontspec. Under the Windows 7 partition it works just fine.
Any idea?
