[Frugalware] [KDE] Problème de polices

Salut tout le monde !

Voilà, je suis sous Frugalware (une distribution Linux pas très connu mais qui est légère, rapide, efficace et persque toujours à jour), j'utilise KDE comme gestionnaire de fenêtre. Mon souci : les polices ne sont pas bien affiché...
En effet, sur mes polices (DéjàVu), je ne peut pas activer la sous-pixelisation des polices, dans kcontrol, cette option de configuration est grisé... C'est le principale problème puisqu'avec la sous-pixelisation je pourrait baiser le taux d'anticrnelage des polices (le halo qui fait un effet de flou dessus...) et avoir des polices net et fines.
Lorsque je supprime le fichier .fonts.conf situé dans mon /home, les polices se réaffiche plutôt bien mais au prochain redémarrage, elle sont directement reconfigurer sans sous-pixelisation...

Je vous donne mon xorg.conf (j'utilise Compiz-fusion) :
