           Summary: HDMI-A-1 Does not work if disconnected at power-up
                    (But claims it does)
           Product: DRI
           Version: unspecified
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel at lists.freedesktop.org
        ReportedBy: Russ.Dill at gmail.com


I have an "ATI Mobility Radeon X1600" (ChipID = 0x71c5). It has four outputs,
VGA-1, LVDS-1, HDMI-A-1, and SVIDEO-1.

I'm running 2.6.37 final (Ubuntu 2.6.37-12.26) and the Ubuntu xorg edgers
1:6.13.99+git20110110.0e432dff-0ubuntu0sarvatt version of
xserver-xorg-video-ati. I'm pretty sure this has something to do with a display
being plugged into VGA-1 as well.

When I plug my laptop into the docking station which the monitor is plugged
into, I get:
