Multiseat with 2 different GPU's


I have integrated intel GPU and discrete NVidia GPU. I'm trying to get a multiseat system working but so far I've only been able to get one GPU to display at a time. Both of my seats work if I only use one at a time like "startx -- -layout Seat1" but when I try to get both of them to work at the same time only Seat0 works.

My xorg.conf:
Code:
Section "ServerLayout"
	Identifier     "Seat0"
	Screen         "Screen0" 0 0
	InputDevice    "Mouse0" "CorePointer"
	InputDevice    "Keyboard0" "CoreKeyboard"
	Option         "AutoAddDevices"	"off"
EndSection

Section "InputDevice"
	Identifier  "Keyboard0"
	Option      "Device"	"/dev/input/by-id/usb-USB_USB_Keykoard-event-kbd"
	Driver      "evdev"
	Option	     "XkbModel"		"evdev"
	Option	     "XkbLayout"	"fi"
EndSection

Section "InputDevice"
	Identifier  "Mouse0"
	Driver      "mouse"
	Option	    "Protocol" "auto"
	Option	    "Device" "/dev/input/mouse0"
	Option	    "ZAxisMapping" "4 5 6 7"
EndSection

Section "Monitor"
	Identifier   "Monitor0"
	VendorName   "Monitor Vendor"
	ModelName    "Monitor Model"
EndSection

Section "Device"
	Identifier  "Card0"
	Driver      "nouveau"
	BusID       "PCI:1:0:0"
EndSection

Section "Screen"
	Identifier "Screen0"
	Device     "Card0"
	Monitor    "Monitor0"
	SubSection "Display"
		Depth     24
	EndSubSection
EndSection

Section "ServerLayout"
        Identifier     "Seat1"
        Screen         "Screen1" 0 0
        InputDevice    "Mouse1" "CorePointer"
        InputDevice    "Keyboard1" "CoreKeyboard"
	Option         "AutoAddDevices"	"off"
EndSection

Section "InputDevice"
	Identifier  "Keyboard1"
	Option      "Device"	"/dev/input/by-id/usb-145f_Trust_Keyboard-event-kbd"
	Driver      "evdev"
EndSection

Section "InputDevice"
	Identifier  "Mouse1"
	Driver      "mouse"
	Option	    "Protocol" "auto"
	Option	    "Device" "/dev/input/mouse1"
	Option	    "ZAxisMapping" "4 5 6 7"
EndSection

Section "Monitor"
        Identifier   "Monitor1"
        VendorName   "Monitor Vendor"
        ModelName    "Monitor Model"
EndSection

Section "Device"
        Identifier  "igpu0"
        Driver      "intel"
        BusID       "PCI:0:2:0"
EndSection

Section "Screen"
        Identifier "Screen1"
        Device     "igpu0"
        Monitor    "Monitor1"
        SubSection "Display"
                Depth     24
        EndSubSection
EndSection
What am I doing wrong here or is it just not possible for Xorg to use two different graphics drivers at the same time?

For starters, you want an instance of Xorg for each session for each seat.

The rest will kind of depend on your distribution, can you give some details?
