Fonts in Lyx

[Néstor]

Hello,

I would like to format a book, I like to use two fonts, one for normal
chapters, another one for some special chapters. The special font
should be looking like handwritten, script.

I have tried to install Kurier font which is the closest choice, but
no luck, it says "uninstalled", even if I have installed it by hand.

When I choose to use any font, I select one, it complaints.

Thank you.
