           Summary: DVI display detected, but won't turn on (tried latest
                    git)
           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: twhitehead at gmail.com
         QAContact: xorg-team at lists.x.org


I have a HP 8501w with a "ATI Technologies Inc M76 [Radeon Mobility HD2600
Series]" graphics card.  It has a HDMI port on the side of it.  My DVI monitor
is detected when I plug it in via a HDMI to DVI cable, but I can't get any
picture to actually be displayed on it.

I am reporting this against the latest git as of 2008/11/17 (the last commit
being 3d27876d).  I do not believe this is not a regression.  It has never
worked with previous versions for me either.  Attached is a log file and the
stdout/stderr (log level 9) generated by starting up and shutting down Xorg
while the the DVI monitor is plugged into the HDMI port via the HDMI to DVI
cable.

I've also attached a dump of the video rom, as was requested in some of the
other bug reports that I was reading, in the event it is helpful.  Let me know
if I can do anything else.

Thanks!  -Tyson

PS:  Something that might show in the logs is that the local LVDS screen didn't
enable itself for this session.  This seems to be the default with this latest
git when an external display is plugged in, but it is actually okay as I have
verified that I can still enable it via "xrandr --output LVDS --auto".
