[lyx-users] How to load a package before the preambule

[Fabien Lafont]

Hello everyone,

I was wondering if it was possible to load a package before the preambule
of the document?

My problem is that I load \usepackage{cmbright}
And if it comes after \usepackage{fontspec} when I use Xelatex the text
switch to latin letters while the maths keep the cmbright font. If I
inverse the two packages I do not have any problem but I can't do it in Lyx
since lyx load automatically fontspec at the beginning

Thanks!

Fabien
