Hi,
I am running OpenSuse 10.2 on Intel Core Duo mqchine using 2
Nvidia 7600 512 Mb cards. I want to run four monitors on this machine
but when I plug them in, Suse detects only two. How can I fix this
problem?
Also, I want to get the function keys to work (as they don't
seem to work at the current moment). Any advice on this?
Before you start, check output of:
/sbin/lspci
to see is the second Nvidia 7600 adapter recognized.
If it is not listed than there is BIOS or other hardware problem that
prevents use of second Nvidia 7600 adapter.
If lspci shows 4 adapters than try to go to YaST -- Hardware -- Display
and see what it shows?
The other place where I would look is /etc/X11/xorg.conf where you will
be able to see 2 sets of entries, probably for 1 of video adapters.
Making copy of present information for first 2 screens, section by
section, and changing numbers from 0 and 1 to 2 and 3, and changing BusID
(PCI bus ID) for second adapter should bring another 2 screens up, unless
there are some limitations in X server.
Below I listed what is different in sections that should exist for 4
monitors of the same kind connected to 2 adapters:
Section "Monitor"
Identifier "Monitor[0]"
Section "Monitor"
Identifier "Monitor[1]"
Section "Monitor"
Identifier "Monitor[2]"
Section "Monitor"
Identifier "Monitor[3]"
Section "Modes"
Identifier "Modes[0]"
Section "Modes"
Identifier "Modes[1]"
Section "Modes"
Identifier "Modes[2]"
Section "Modes"
Identifier "Modes[3]"
Section "Screen"
Device "Device[0]"
Identifier "Screen[0]"
Monitor "Monitor[0]"
Section "Screen"
Device "Device[1]"
Identifier "Screen[1]"
Monitor "Monitor[1]"
Section "Screen"
Device "Device[2]"
Identifier "Screen[2]"
Monitor "Monitor[2]"
Section "Screen"
Device "Device[3]"
Identifier "Screen[3]"
Monitor "Monitor[3]"
Section "Device"
BusID "1:0:0"
Identifier "Device[0]"
Section "Device"
BusID "x:x:x"
Identifier "Device[1]"
Section "Device"
BusID "x:x:x"
Identifier "Device[2]"
Section "Device"
BusID "x:x:x"
Identifier "Device[3]"
The x:x:x you can pick up from command
/sbin/lspci
Edit:
Section "ServerLayout"
to add another 2 screens.

Thanks for the help! However, I am just a newbie to Linux and
my command like knowledge is close to zero. So although I can reach
the sbin directory, I really do not know the command for displaying
the output of the Ispci file or editing the xorg.conf file. I do
really understand what you are trying to say but lack of command line
knowledge is acting like a major bottleneck. It would help me if you
are slightly more detailed, cut-pasting your commands from the Konsole
would be of great help. Thank you so much!

Rohan,
OK.
In the other post you mentioned that no graphic in runlevel 5.
Obviously something went wrong with /etc/X11/xorg.conf file.
You mentioned in third separate post same PCI BusID, that will not work.
That is the reason I asked you to check first with command
rohan@linux:~> /sbin/lspci
what is found on the system. That is the command that you have to type on
command prompt in user terminal.
If system see only one card or one half of 2 cards than we have to find the
way to bring that in order first, if possible.
I have forgotten to say to make backup copy of xorg.conf, it is time to do
that now.
You are in the text mode. Login as root and change directory:
linux:~# cd /etc/X11
linux:/etc/X11 # cp xorg.conf xorg.conf-4screens
This will save your changes, as I guess there is a little to edit, to bring it
in order. The
linux:~#
is command prompt, you have to type only what comes after #.
To list all xorg.conf files:
linux:/etc/X11 # ls xorg*
xorg.conf xorg.conf-4screens xorg.conf.md5 xorg.conf.install
xorg.conf.saxsave
The xorg.conf.saxsave is the best candidate to copy back to xorg.conf, if it
is missing than use xorg.conf.install, the xorg.conf.md5 is only md5 check
sum of current xorg.conf:
linux:/etc/X11 # cp xorg.conf.saxsave xorg.conf
linux:/etc/X11 # init 3
if you don't see command prompt, press Enter and it will appear. Now we can go
back to graphic mode:
linux:/etc/X11 # init 5
Main Menu--System--Terminal--Terminal Super User Mode
to start Terminal (or Konsole). It will ask you for a password, give root
password.
Now, let we see what cards are recognized.
linux:~# lspci
will list all PCI devices, you can copy and paste it to email and we can go
from there.
The same you can do with xorg.conf-4screens:
linux:~# cat /etc/X11/xorg.conf-4screens
<here you will see longer listing, scroll to the begin and copy and paste it
to email.
