moin moin,
turns out xorg.conf can still be used. Created a file with a screens
section and a virtual entry and both displays work.
That should be able to run dual digital displays. But it may require the
mad driver to do it. It should be a shared ramdac and gpu. So unless the
did something weird on port it should work with the right driver in play.
mad driver? Is that the UPS guy from the show? :)
It would be awesome if I could get both working via digital. I didn't
retry that after getting virtual setup.
Previous tries didn't work because bios and boot up wouldn't display if
both were plugged in, so I was already having problems before X. I need to
be able to see boot up because I currently intentionally require an
interactive boot process. While the interacive could involve unplugging
and replugging a cable, I'd rather not.
I'll try a few things, though.

moin moin,
because there is so much difference in how they implement VGA (limited
resolution, analog out, sync pulses, etc) and digital they many "dual
head"
display drivers have one of each to make sure that what ever type of
display you have, they can drive at least one. So I fear that you quest
for
2 digital displays is likely to fail, or require new hardware, not just
new
software.
Ah, so one chip for digital that can feed one display and another chip for
analog. Kinda what I was figuring.
What are you using for video? X? You might need Xinerama to get full use
of
both screens.
I would prefer to use xrandr. Besides, Xinerama is so 2000's :).
In either case, I still think it needs to be able to drive that much
display. Not sure why the proprietary driver can and the Free Software
driver can't.

moin moin,
It looks like I can get 2 out of 3 as long as the two aren't HDMI and DVI
:(. With cables plugged into both ports I can't even see post. Remove one
and suddenly lights are on.
Using either HDMI or DVI with VGA works, though.
Now I just need to figure out why wheezy demands on cloning the output.
I'm hoping to find a solution that doesn't require installing the
proprietary driver :).
ciao,
