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@lists.freedesktop.org ReportedBy: Russ.Dill@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:
