Triple monitor with intel and SenseVision Club 3d usb to hdmi adapter

Hi,

I have an all in one machine with a single intel VGA:

00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v2/3rd Gen Core processor Graphics Controller (rev 09)

I also have an external monitor which works fine. I would like to use a third monitor through the SenseVision Club 3d usb to hdmi adapter (Chipset: DL-195).

I'm using the udlfb module with the option: fb_defio=1

The monitor attached to the usb to hdmi adapter turns green when the machine starts.

The problem is that I'm able to use only one adapter at the time. So I can use the integrated monitor and the external one attached to the intel VGA or the monitor attached to the usb to hdmi adapter but not all of them together.

Here is my xorg.conf:

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

Section "Device"
	Identifier      "dl1"
	Driver          "fbdev"
#	BusID 			"PCI:0:3:0"
	Option  "fbdev" "/dev/fb1"
EndSection
 
Section "Monitor"
	Identifier "monitor0"
EndSection
 
Section "Monitor"
	Identifier "monitor1"
EndSection

Section "Monitor"
	Identifier "monitor2"
EndSection

Section "Screen"
	Identifier "screen0"
	Device "dl1"
	Monitor "monitor0"
	#DefaultDepth 16
	#DefaultDepth 24 
EndSection
 
Section "Screen"
	Identifier "screen1"
	Device "intel"
	Monitor "monitor1"
	#DefaultDepth 16 
	DefaultDepth 24 
EndSection

Section "Screen"
	Identifier "screen2"
	Device "intel"
	Monitor "monitor2"
	#DefaultDepth 16
	DefaultDepth 24 
EndSection

 
Section "ServerLayout"
	Identifier     "multihead"
	Screen      0  "screen0" 0 0
	Screen      1  "screen0" LeftOf "screen1"
	Screen      2  "screen1" LeftOf "screen2"
	Option    "Xinerama" "on"
EndSection

Switching the screen0 and screen1 positions in the xorg.conf makes work the intel vga. The current configuration enables only the usb monitor. The screen2 is discarded by the xorg stating that none monitor is attached to the device.

I also tried to tinker with the BusID values. Specifying BusID "USB" makes the xorg crash.

Is it possible at all to use three monitors at the time with the current state of art? Any success story with this setting?

Could you please share your working xorg.conf if you have any?

Any suggestion?

Thank you very much.
