Xorg.0.log starting X verbosity 7
driver: radeonhd-1.2.5 (local-overlay); xrandr-1.2.3
graphic card: Radeon HD 4670 (MSI R4670)
I can't get my second port of the graphic card working.
I'm using 2 monitors the one plugged into the first port of my card always show X fine but the second one does only show a black screen or grey small vertical stripes on black background.
If I set something like a resolution using xrandr the second monitor reacts for a short time and shows a gray big grey horizontal stripe.
I tested the card against failures using Windows Vista and the vesa driver. Both display the desktop on both monitors which means the card isn't broken and both monitors are working.
One monitor is connected using DVI and the other using VGA with DVI-VGA converter.
I tried forcing a resolution for both screens and setting up dual screen in Xorg.conf.

update of Xorg.log after using git-sources
Does this issue occur with the preferred ati driver (xf86-vide-ati)? If so, please move this to the Driver/Radeon component.
Development of radeonhd has pretty much halted and development focus is on the ati driver. Please see http://www.x.org/wiki/radeonhd
If the issue does not exist in the ati driver (or if there is no response to this message), this bug will be closed as WONTFIX unless someone contributes a patch.
Closing due to lack of response. Please reopen and move to the Driver/Radeon
component if this issue persists with xf86-video-ati
