Correct me if I am wrong but wasn't the OP "Using monitors attached to
TWO video cards together?"?

Vilmos, thanks. If you could post the contents of your xorg.conf, I
would be very grateful. Thanks a lot.

OK. All machines have nvidia cards, and we use the bin nvidia driver.
I am going to describe two machines.

1. one nvidia card, X.Org X Server 1.4.2, Release Date: 11 June 2008

$ lspci | grep -i vga # lines broken to honor line length

2. this is a rather old and special-use machine.
three nvidia cards,

XFree86 Version 4.3.0.1

This second machine is the box where after bootup, sometimes we need
to restart X a couple of time so all the cards are seen and in order.

Writing and testing the xorg.conf file:

Once you wrote a section of the conf file, test it. Your main testing
section is the ServerLayout. Once you wrote a Device/Screen section,
test it in the ServerLayout section. Don't worry about the multi-monitor
stuff yet. Just ensure that all videocards/heads are configured correctly.
Essentially your ServerLayout section will only have one Screen statement
and the relevant keyboard/mouse confs.

Once all heads are ok, then you can start to do the multi screen stuff
in ServerLayout.

Actually, it may be because you are an ignoramus at Googling.

Well, maybe you can point me to some up to date writeup on this, then?

Apparently this guy did it with Ibex, If you are still running Hardy
LTS it might be applicable, and still it point in the right direction
for Lynx... it was the first hit on googling...

http://ubuntuforums.org/showthread.php?t=53966

That link is old as hell.

In relation to WHAT?

Lots of links are old but valid.

I have to agree. I don't recall which version OP was trying to make this
happen. If it is 8.04 LTS then it is very applicable. Also even though
in 10.04 they have changed xorg, you still can use xorg.conf to tweak so
it still might be useful.


10.04.

Right now, I have a computer with ONE card and THREE monitors. It sits
right next to me and I am about to start messing with it.

A lot of cards have three outputs but only two internal pipelines,
therefore you can't make three outputs work at once with those cards.

That's true for the onboard video of this new motherboard I'm using.
VGA, DVI, and HDMI outputs are present, but you can use only the following
combinations:

VGA+DVI
VGA+HDMI

Actually, I was pleasantly surprised. I thought I would have
to install a spare Radeon card.

I'd love to know if the reason that onboard share video usually doesn't

work with, say, an AGP card, is hardware or something regarding
software. I don't follow why similar chipsets when used in a notebook do
work as dual head. It seems odd.

Hmmmm. I have access to a third monitor. Time to play with a second audio
card?

Well, this mobo does do dual head. I've got a meter's worth of horizontal
desktop space.
