NV dual monitor setup ...crashing.

["Martin S. Weber" <Ephaeton%gmx.net@localhost>]

Yo,

I've tried today to setup my new machine (a nice piece of dell t5400)
with two monitors. It has a single Nvidia with two Y plugs so you can
set it up with up to four monitors. I wanted to run two independent
screens on it. Xorg -configure (pkgsrc-2008Q3) spit out a config file
with two 'Device', 'Monitor' and 'Screen' sections ... which sadly
will crash the X-Server. I see both monitors going on for a moment,
but then that's it.

Does anybody have experience with that kind of setup? Some googling
turned up 'Dual Head' option, but that just mirrors the same screen
on both monitors (and I have to plug both into the same 'Card').
As all the files are a bit lengthy, I have uploaded some stuff for
the interested/knowledgable to look at:

http://ayaken.net/dmesg.boot.uranos
http://ayaken.net/xorg.conf.new.uranos
http://ayaken.net/Xorg.out.uranos
http://ayaken.net/Xorg.0.log.uranos

The file 'Xorg.out.uranos' contains both the console messages of
starting Xorg -config xorg.conf.new (which I have renamed afterwards)
as well as a 'bt' from the Xorg.core file, which I duplicate here:

Core was generated by `Xorg'.
Program terminated with signal 6, Aborted.

(gdb) quit

Hints on how to configure / what to do to get this working are
greatly appreciated (and might result in an invitation to consuming
some home-brewed beer if coming from the DC area)
