[Libdlo] only greenscreen --- Samsung LD220 and Ubuntu 9.10

[Daniel Hindenlang]

Hello,

I get a new Samsung LD220. Now I want to use it with USB on my Notebook. 
I just pluged it in and the dmesg is:
> [  230.735419] DisplayLink device attached
> [  230.735581] ret control msg 0: 4 1500fffffff1

After this I changed the xorg.conf:

Section "Device"
    Identifier    "Configured Video Device"
    Driver        "vesa"
EndSection

Section "Monitor"
    Identifier    "Configured Monitor"
EndSection

Section "Screen"
    Identifier    "Default Screen"
    Monitor        "Configured Monitor"
    Device        "Configured Video Device"
EndSection

Section "ServerLayout"
        Identifier      "Server Layout"
        Screen  0       "Default Screen" 0 0
        Screen  1       "DisplayLinkScreen" Rightof "Default Screen"
EndSection

Section "Device"
        Identifier      "DisplayLinkDevice"
        driver          "displaylink"
        Option  "fbdev" "/dev/fb0"
EndSection

Section "Monitor"
        Identifier      "DisplayLinkMonitor"
EndSection

Section "Screen"
        Identifier      "DisplayLinkScreen"
    Device          "DisplayLinkDevice"
        Monitor         "DisplayLinkMonitor"
 EndSection


When I reboot now I only get a greenscreen on the LD220 and my xserver 
doesn't start. The tty's are broken too.

Any suggestions??

Sorry for my bad english.

Regards and merry christmas,
