rv100, second video card, tv out

Tue Mar 15 06:49:49 PDT 2011

I don't have physical access to the machine today, so I can't reboot it
to change the primary adapter. Here is an extract from the dmesg when
the ATI card is primary. At first, I tough that the "No TV DAC" message
was relevant, but it is also present when the ATI is primary.
The obvious difference here (I guess that's not so insightful)
is the presence of Connector 2.
