Fedora 13 with 2 NVIDIA grapic cards

[Sodiac]

Hi.

I'm trying to get my Fedora 13 to run with two NVIDIA quadro 600 grapic cards.
I need to be able to connect 4 screens with a different picture on each screen.
At the moment the initial OS install runs fine untill I start installing the NVIDIA driver for the quadro 600 cards.

When I reboot my machine after installing the driver it crashes in the booting face just as the graphical(init 5) interface is about to start.

I'v tried running one "quadro 600" card and one "quadro NVS 295" card to see if it could work if I had two diferent cards connected, but then I wasnt eaven able to install the OS.

If I only use one "quadro 600" card evrything works fine, eaven after the driver install. so I'm guessing Fedora 13 doesnt allow the installation of two graphic cards?

Did you blacklist nouveau

su -
sed -i '/root=/s|$| rdblacklist=nouveau nouveau.modeset=0|' /boot/grub/grub.conf
mv /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r)-nouveau.img
dracut /boot/initramfs-$(uname -r).img $(uname -r)

I believe so.
Seeing as it works with only one grapic card physically installed. I only run into troubles when I try to install a 2nd card.

Try allocating more virtual memory


su -
sed -i '/root=/s|$| vmalloc=256m|' /boot/grub/grub.conf

Thanks, I'll try that asap

Sorry about the late reply. Took some time finding out how to get my machine to boot.
I tried it out with no result.

You'll probably have to boot up in run level 3.
run lspci to get the BusID of both cards.
then edit /etc/X11/xorg.conf to add a second "Device" section
should look something like this: just substitute your card names & numbers

Section "Device"
Identifier "GeForce GTX 285"
Driver "nvidia"
VendorName "NVIDIA Corporation"
BusID "2:0:0"
EndSection

Section "Device"
Identifier "GeForce GTX 285"
Driver "nvidia"
VendorName "NVIDIA Corporation"
BusID "5:0:0"
EndSection

dug up some more documentation; It's for F16 but the same rules should apply.

sounds like you'll need a device entry for each screen & link it to a specific card..

I have 3 boxes running dual cards, so I know it's not a Fedora issue. One box has a GTX275 Paired with a 9800GTX+, so mis-matched cards are ok as long as they can use the same driver.

My set up has a monitor connected to only one card, the second card is only for crunching numbers.
