           Summary: xorg sets wrong resolution when 2 monitors are
                    connected
           Product: xorg
           Version: git
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: benderamp at gmail.com
         QAContact: xorg-team at lists.x.org


I have xorg 7.6 from opensuse factory, ATI r600 card with opensource driver. 2
monitors connected with DVI: 

- DVI-0 - monitor with 1280x1024 preferred resolution connected with DVI2DVI
cable
- DVI-1 - TV with 1028x720 preferred resolution connected with DVI2HDMI cable

If both cables are connected when system boots, I receive 640x480 in kdm and
also on the desktop (both on dvi-0 monitor and on dvi-1 tv). I can fix this in
kde system config "display and monitor"/"size and orientation" module even
without restarting X, but when I reboot comp, the resolution is again reset to
640x480.

If I remove DVI-1 cable (with TV) and resboot, I receive correct 1280x1024 on
DVI-0 monitor both in KDM and on the desktop automatically without making any
additional configuration.
