I have been trying to get a dual monitor set-up working, and am getting no where
with this, so it is time to request help.
I have a Dell Precision T5500 with dual video cards, and I would like to have
one large screen spread across the two monitors. The graphics cards are nVidia
Quadro 600s, with a monitor connected to each DVI output. I am not concerned
about performance, since the most graphics intensive stuff I do is surfing the
web and database development, but I would like to be able to develop in a
terminal on one monitor and see the results in the application on the other
monitor.
This is a stock installation of Squeeze, other than a "custom" 3.5.1 kernel
package made with make-kpkg. I say "custom" because the only configuration I did
was to de-select the paravirtualized (or something close to that) option, and
then compile the kernel, along with all modules.
I am not sure where to start. One thing I have tried to do is to see what xrandr
gives me, and I don't completely understand the output of that. I have included
that output, and a copy of Xorg.0.log below.
At this point I would welcome any suggestions as to what to try next.
All the best,
Nelson

I usually do this with a single graphics card. So my suggestion might
not be useful to you. But...

I would start with lxrandr. Because even me being a staunch CLI
advocate it is sometimes easier to click the mouse. This is simply an
graphical interface to xrandr.
# apt-get install lxrandr
$ lxrandr
It also installs a menu for it under Applications/System/Monitoring
as LXRandR too so you can menu pick it instead of typing it. Then see
if it allows you to turn on and set up both monitors.
Then for batch mode automated startup I have the following in my X11
startup file.
if xrandr --query | grep -q HDMI2; then
xrandr --auto --output HDMI2 --right-of HDMI1
fi
Initially both of my monitors have the same display. Setting the
above command sets my second monitor to the right of my first monitor
and then they display one unified display.
Again, I am using a single graphics card with dual outputs. YMMV.

Unfortunately, lxrandr only shows the single monitor. Another issue I
have is nothing from xrandr nor lxrandr shows an output interface. If
I could get that information I might at least have a place to start. As it
is, the only indications that the two cards are even known to the system
are the Xorg log, and the output of dmesg. Other than that nothing
seems to be aware of the second video card and/or monitor.
BTW, I also realized I forgot to mention that I am using the Xfce
Desktop. I doubt that makes any difference, but figured I should at
least mention it for completeness.
I appreciate the reply.

It is possible that the 'nouveau' driver doesn't do dual monitors with the Quadro
600 cards. i am not to good with these things, looks like it tries 'nouveau,
vesa & FB, and fails. ,
I do run a Quadro dual port card, I use the 'nvidia' driver, the xorg drivers do
not work with my setup. The Nvidia driver comes with a monitor setup app, works
here.

Hi Shane,
No, I do not have an xorg.conf file. In fact I am curious to know how
not having that file works, if anyone would care to point me to a
source of info on that. I'm used to having a configuration file for
almost everything.
In the meantime I may just see if I can find a different set of video
cards, or a dual port card that are/is supported. What are the chances
of finding a list of supported configurations/hardware?
Thanks,
Nelson
