You must manually configure /etc/X11/xorg.conf

Mine is (relevant parts only):

# xorg configuration

Section "ServerLayout"
        Identifier     "ATI dual head configuration"
        Screen      0  "Default Screen" 0 0

        InputDevice    "Keyboard0" "CoreKeyboard"
EndSection

Section "Module"
    .......

EndSection

        Identifier   "Panel-1"
        VendorName   "Monitor Vendor"
        ModelName    "NEC MultiSync LCD1700NX (Digital)"
        # Comment all HorizSync and VertSync values to use DDC:

EndSection
