Thanks for your prompt reply.
Unfortunately this doesn't work either. I already tried this settings as
this was one of the modelines I found with google.

I also tried the newest Ubuntu Live-CD with the same results (xserver
1.4). But I will check again, if this version auto-detects the edid
values correctly.

And even worse, my monitor doesn't provide any error output. I just
stays black.

Maybe this problem is really because my video card can't provide the
right signal?
Is there anybody out there who runs a radeon 9000 with a resolution of
1920x1200px?

Best regards,
	Andre
