Hello I'm hoping someone can help me out with this.
I've been using debian sarge for some time now with 2 nvidia cards and 4 monitors everything worked find. I've now decided to give etch a try, and noticed that x86config is now replaced with xorg.conf. By documentation things should work similar, however try as I might I can't get muliti screens to work.

For testing I've just used 1 card and 2 screens I've set up the following

Section "Device"
Identifier "Card0head0"
Driver "nv"
BusID "PCI:0:9:0:0"
Screen 0
Endsection

Section "Device"
Identifier "Card0head1"
Driver "nv"
BusID "PCI:0:9:0:0"
Screen 1
Endsection

I've set up 2 monitors and 2 screens

in the server layer I've set up my screens, if I use one screen eg

Screen "Screen0"

it works great. However if I add a second screen with

Screen "Screen1" Below "Screen0" it crashes. This happens if I use

Screen 0 "Screen0" 0 0
Screen 1 "Screen1" Below "Screen1"



The error I get is
*************************************************************
NV: No matching device section for instance (BusID PCI:0:10:0) found

fatal server error

Requested entity already in use XIO: fatal IO error 104 (connection reset by peer) on Xserver "0:0" after 0 requested (0 known process) with 0 events remaining.

Although my second graphics card is on pci10 I'm not addressing it in my device set up, also if i try to use just one screen from my second card it won't work either, also if I try to use a single screen from card 0 usng the second head it doesn't work either. I'm now starting to this their is a problem with either etch or Xconf or the documentation is incorrect. I should add the etch I'm using is netinstall testing. Thanks

lspci -X should give you those numbers, but i don't think that this is the problem, I think you should hv a look on the nvidia driver manual.. well I think you don't use the nvidia driver as you put nv on the driver section... why don't you try that?

Hi found the answer, there is a problem, he's the answer I'm sure other people will have he same problem.

1 don't use nv driver download nvidia.

2. after you install etch make sure you apt-get install xserver-xorg-dev, you need this or your nvidia KLM's will install incorrectly.

So
a install etch
b apt-get install x-server-xorg-dev
c install nvidia drivers.


There's a few other answers on the net about moving files around, but you don't need to do any of that if you install the xserver-xorg-dev
