xorg.conf

A 1920x1080 LCD monitor on DVI output is driven
semingly at half dot clock, monitor displays "33 kHz x 30 Hz"
horizontal and vertical frequencies, for a 1920x1080x60Hz mode.

The image is somewhat unsteady, and grayscales look dithered, as if 
it uses less than 8 bits per pixel.

After about one minute, monitor switches off.

This only happens on the DVI output, the VGA is running fine.

Hardware is a Kontron kt690-mITX board, with embedded ATI RS690
graphics. 

I'm running ubuntu jaunty, with xorg-edgers ppa, which be quite update with
respect to the radeon driver        
xserver-xorg-video-ati 1:6.12.99+git20091009.f4407962-0ubuntu0tormod~jaunty. 

I've tried to switch modes with xrandr, works fine on VGA, but 
on DVI the same symptoms persist, even in different resolutions.
Always the monitor complains about frequencies out of range, and vertical
refresh is about 30 Hz.

I'll attach my xorg.conf and the Xorg.0.log.

BTW, the board also has a LVDS connector, which is empty, but Xorg 
wants to drive it at 1280x800, so try to disable that output with an extra
monitor section with the line
Option "Disable" "true"

not sure if that actually works, xrandr reports the LVDS anyway.
Turning it on with xrandr gives an CRTC error though.

If I set 
Option "Ignore" "true"
for the LVDS, xorg fails completely, saying it does not find any screen!

But that is maybe another bug...
