           Summary: DVI-1 connector doesn't work; Radeon HD 3470
           Product: xorg
           Version: 7.4
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: freedesktop at juch.cc
         QAContact: xorg-team at lists.x.org

The DVI-1 connector doesn't work with the following PCI-E card (Sapphire HD
3470, passively cooled) and the current radeon driver from git:

01:00.0 VGA compatible controller: ATI Technologies Inc Mobility Radeon HD 3470

The card has two DVI connectors. xrandr output says that the DVI-1 output
should be working, when I take a screenshot, it has the correct dimensions.

   720x400        70.1  

At Xorg startup the monitor connected to DVI-1 seems to be initialized because
the monitor wakes up from standby, but immediately displays "No signal
detected" and goes to standby again.

When I swap the connected DVI cables, the other monitor works (in fact only the
monitor connected to DVI-0 works), so no hardware defect. I previously used
this setup successfully with fglrx and radeonhd.

The problem seems not to be related to DPMS ('sleep 5; xset dpms force off'
doesn't help).

Xorg log and config are attached.
