Sorry, ben er even een paar dagen niet meer mee bezig geweest. Ik heb inmiddels de HD 3450 vervangen door een HD 5XXX series.De 3450 is namelijk unsupported door de AMD drivers.... Echter is nu de situatie wat anders. Als ik de open source drivers gebruik werken de drie monitoren wel en kan ik de desktop ook over deze monitoteren verdelen. Alleen is alles dan zo ontzettend traag, dus ik heb de AMD drivers nodig ivm met performance.
Nu heb ik de laatse drivers geinstalleerd en zie ik 3 monitoren in de Catalyst Control Center. Mijn monitoren heb ik zo aangesloten:
Apu >>>Monitor 1 (HDMI) , Monitor 2 (VGA)
GRAKA >> Monitor 3 (VGA)
Ik kan echter de 3e monitor, die op de Graka is aangesloten, niet selecteren om mijn destop op uit te breiden. Bij de overige 2 monitoren heb ik de mogelijkheid om multi display desktop te kiezen, bij de derde monitor alleen single display destkop. Deze toont nu ook een mooi grijze achtergrond met een X als cursor

Ik heb al wat lopen spelen met xorg.conf, deze (niet correcte) heb ik nu:
