have 2 monitors connected to my pc, but lspci only finds 1.. help


Hi all. ive got this weird problem

ive got 2 identical fujitsu siemes monitors connected to my pc.
The first one on an AGP card and the second one on an onboard connection.

At the moment ive got the same screen on both monitors.. that is..
its cloned. Thats all well and dandy, but now i wanna try xinerama
with an expanded desktop spanning both monitors.. but thats
where my problem comes in.. lspci only shows 1 graphics card (seems to me its the onboard card)
anyone know what i need to do to find my second card?

heres the output from lspci:
midas:~ # lspci
00:00.0 Host bridge: Intel Corporation 82865G/PE/P DRAM Controller/Host-Hub Interface (rev 02)

afaik theres only 1 graphics card on that list.

any and all help appriciated.

nappy

ps: seeing that i DO have X on both monitors, only its cloned...the
signals must somehow find its way there.. but i cant see how!??

pps: using suse 10.2

ppps: header really should say: have 2 graphics cards on my pc, but lspci only finds one

Are you sure you have an AGP card, not a second connector on the integrated graphics?

I assume "00:02.0 VGA compatible controller: Intel Corporation 82865G Integrated Graphics Controller (rev 02)" is the graphics on your motherboard, so lspci isn't listing your AGP card.

What cards do you see in /var/log/Xorg.0.log?

yikes. you are correct. the second card isnt an AGP card after all.
in fact, when i take a closer look at it, it seems that its part of
the mainboard. all my pci(express)/agp slots are in fact free.
So.. what does this mean.. it means that both my monitors are connected
to the mainboard, but at different locations (i.e they are not side by side) like they do on dualcards.

im not sure how to interprent this.. can they be using the same bus
eventhough the DVI/VGA ports are on different locations on the board?

The physical location for the second connector of a motherboard display adapter can be almost anywhere. The physical location doesn't matter for the behavior.

I'm sure that Intel adapter can be configured for xinerama. Maybe it can also be configured for some xinerama-like behavior within its own driver (giving faster performance and mabe other benefits vs. using xinerama). But I have no experience with Intel graphics controllers, so I'm not the one to tell you how to do any of that.
