           Summary: dual head not working on sapphire radeon 4670 (HDMI,
                    DVI)
           Product: xorg
           Version: 7.4
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: prusnik at gmail.com
         QAContact: xorg-team at lists.x.org


I just bought Sapphire 4670 Ultimate with DVI, HDMI and VGA output and replaced
a 4350 dual DVI card.
I tried activate dual head but apparently, from what I gather the driver or
xorg does not consider that I have 2 monitors it only ever defaults settings to
the monitor that is connected to the DVI and then forces the same settings to
HDMI connected monitor.
If I try to via randr or gnome display settings to uncheck mirror (or say
right-of under randr) then on both monitors I see the right-of part of the
display. It looks as though the left screen (HDMI one) does not get the proper
output.

Under windows 7 displays are correctly layed out automatically (HP left -
basic, Philips right-of - extended) so the card is able to do that.

Also the previous dual DVI card (4350) could properly handle dual head with
these settings I'm describing.

I'm attaching the xorg logs and the config.

I user latest mesa/drm and radeon driver in kms mode, with kernel 2.6.32.
