** Depending first of the font format. PS fonts (or using PS outlines
like OTF), hinting is made with stemH and stemV. TTF (or truetype
outlines) initial hints are "transformed" into TT instructions.
Fontforge is a very good tool to do that, but for TT the best way is to
use Xgridfit by Peter Baker, and his Junicode fonts have this technology.
Fonts are programs inserting tables used by other apps. Now,
all depends how they work in your system. As Rolf said, many
things should explain screen troubles (but not for printing).
AFDKO from Adobe has command lines tools to hint PS fonts only.
If you are Windows user, install cleartypePowerToy. This one could rule
some problems (most of them)

Freetype2, is a very good rendering engine...
Just try a live CD with linux to see changes :-)
I don't know how Scribus uses the font realy, but how this ones
appears on the screen not depending from it, I think. Now, how
your documents are printed ?

** Strangely not only free fonts ! other problems could appears with
too many points, node not at extrem, overlaps, bad direction...
This is also true for fonts converted as web fonts without
followed font format specifications.
I'm working to a "new" TTF (not realy new but more to change
some Table values). The next step will be to work dirrectly with
Xgridfit into FF... under development...
I'm very interesting by feedback off list

** Not sure to understand. Kerning just rules side bearing values
between 2 glyphs like VA or WO. Generaly I make Hint at the end
when nothing more is needen and all changes and adjustments are made.
Maybe I wrong here.
