That definitely fixed my screen (for now)
There's still the issue with have no mouse, but i probably guess i have to configure it in xorg.conf aswell?
I found a nice howto on configuring X so i guess i have to do some more reading.
To bad i don't have so much time the coming days so i'll fix that one later.
In time i want to have a dual screen setup..
Thanks for your help and getting me on the right track!
