intel driver with ADD2 card - getting dual independent displays working

[Dan Naughton]

I've been at this for a few hours, I have both DVIs from the ADD2 card
working in clone mode, but I can't get them to work independently.
There is one snippet in the Xorg.0.log file that looks suspicious:


(II) intel(0): Output configuration:
(II) intel(0):   Pipe A is on
(II) intel(0):   Display plane A is now enabled and connected to pipe A.
(II) intel(0):   Pipe B is off
(II) intel(0):   Display plane B is now disabled and connected to pipe B.
(II) intel(0):   Output TMDS-1 is connected to pipe A
(II) intel(0):   Output TMDS-2 is connected to pipe A
(II) intel(0):   Output TV is connected to pipe none

I think I want it to say : Output TMDS-2 is connected to pipe B

I can't find anything anywhere that says what TMDS-1,2 are.  I was
assuming in was SDVO 1&2 from the ADD2 card.  I think that's all
that's left.  My motherboard has has the 945GM on it with VGA,LVDS,TV
and the two SDVO outputs.  I think I shut off the VGA and LVDS screens
with the "bogus" screen section.
