[Libdlo] Only greenscreen ----searching for suggestions a long time

[Daniel Hindenlang]

Hello,

I want to run my Samsung LD220 Lapfit Monitor with my Notebook running 
Ubuntu 9.10

I've just pluged it in and I only get greenscreen.

Here the dmesg messages:

I search for suggestions for many days and I test a lot of stuff but I 
cant fix it :(

Does anybody know, how I can solve this problem?

Thanks and greetz from germany
