[Libdlo] Can't startup displaylink device correctly under ubuntu 9.10

[responder.member]

hi all,
 
I was tried to use my device link device under the latest ubuntu 9.10 (64
bit) on my laptop (Acer 4736G with NVIDIA G105M) with no luck.
 
My "Buffalo GX-DVI/U2" can be detceted correctly when I plugged it into the
system.
The screen will become green as mentioned by Bernie.
 
Then I followed the instruction of
http://mulchman.org/blog/?p=21
&
http://libdlo.freedesktop.org/wiki/Ubuntu9.04
 
The xf86-video-displaylink can be compiled correctly.
However, I found the following errors on Xorg.0.log
=====
(II) LoadModule: "displaylink"
(II) Loading /usr/local/lib/xorg/modules/drivers//displaylink_drv.so
(II) Module displaylink: vendor="X.Org Foundation"
        compiled for 1.6.4, module version = 0.0.1
        ABI class: X.Org Video Driver, version 5.0
(II) DL: driver for : displaylink
(WW) Falling back to old probe method for displaylink
=====
 
The following is my  xorg.conf. (w/ or w/o Xinerama didn't help.)
=====
Section "Screen"
        Identifier      "Default Screen"
        DefaultDepth    24
EndSection
 
Section "Module"
        Load    "glx"
EndSection
 
Section "Device"
        Identifier      "Default Device"
        Driver  "nvidia"
        Option  "NoLogo"        "True"
EndSection

        driver          "displaylink"
        Option  "fbdev" "/dev/fb0"
EndSection

        Identifier      "DisplayLinkMonitor"

        Monitor         "DisplayLinkMonitor"
        SubSection "Display"
                Depth   24
                Modes   "1400x1050"
        EndSubSection
EndSection

======
 
 
I also tried to mark the NVIDIA's section and let DisplayLink be the default
ouput.
The X can show without the login screen.  : (
I must miss something but just can't find where.
 
Please kinldy show me some hints about it.
 
Thanks in advance.
