Bug#627568: [xserver-xorg-video-nouveau] Dual head problem: Flicker on 2nd monitor using GeForce 8500 GT

Just as a little bit of extra info:-
I think there is a problem with the reading of the EDID on the 2nd
graphics card output with the nouveau driver on this nVidia card.
I tried a much more modern monitor in the 2nd output and there was still
no reading of the EDID.
(I ran: xrandr --prop )
The drm_kms_helper.poll=0 kernel parameter still fixed the blinking.
The primary output on my card is a standard VGA connector.
This 2nd output (physically) is a DVI-I output running in analogue mode.
I use an adapter to change the connection to VGA as I don't have a
monitor with a connector of any type other than VGA.
I don't know if this adapter has a bearing on the monitor's ability to
report its EDID to the card?
Cheers!
