Hi, die 16 Bit Farbtiefe kannst du in deinem /etc/ Verzeichnis in der Datei XF86Config in der Screen-Section die zu deiner Grafikkarte gehoert mit dem eintrag DefaultColorDepth 16 einstellen. Bei mir steht der eintrag in der Screen Section fuer den SVGA Treiber, da die Matrox Millienium den SVGA-Treiber benutz. Fuer deine Grafikkarte musst du die entsprechede Screen Section aendern. Als Beispiel hier ein Auszug aus meiner XF86Config: ....
