           Summary: S-Video incorrectly detected on RV515
           Product: xorg
           Version: unspecified
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: bacn at zhasha.com
         QAContact: xorg-team at lists.x.org


When X starts it will incorrectly report that a monitor is connected through my
Mobility Radeon X1400 (M54/RV515) S-Video port, even though no cable is in the
port. This then causes GDM at least, to select the best common mode between the
LVDS and S-Video, which happens to be 1024x768, thus showing a stretched and
blurry picture on the LVDS.

This happened for the first time on the Fedora 12 live-cd. Approximately 1 or 2
weeks prior to the F12 release I had used Rawhide with no such bug.

Reproducibility:
Every time

Steps to reproduce:
Start the F12 live-cd or any F12 installation on the appropriate card.

I have attached the VBIOS for my card on recommendation of airlied. Hope this
helps and thank you in advance.
