The card is a completely separate card. One can create a very old-fashioned
Xinerama-based dual-head setup using this (save as
/etc/X11/xorg.conf.d/60-dualhead.conf):


Section "Device"
    Identifier "radeon"
    Driver "radeon"
    BusID "PCI:22:00:0"
EndSection

Section "Device"
    Identifier "intel"
    Driver "intel"
    BusID "PCI:00:02:0"
EndSection

Section "Screen"
    Identifier "Screen0"
    Device "radeon"
EndSection

Section "Screen"
    Identifier "Screen1"
    Device "intel"
EndSection

Section "ServerLayout"
    Identifier "DualHead"
    Screen "Screen0"
    Screen "Screen1" RightOf "Screen0"
    Option "Xinerama" "On"
EndSection


This is, however, deprecated, and I'd also like to know the modern way of doing
this :)
