Configure two video cards (ATI and Nvidia)

[ice00]

hi,

Due to the miss of proprietary drivers from AMD for Fedora 12, I have installed a second video card in my system (a Nvidia one) for BOINC calculation. This card is not connected to a monitor.

So in the system I have this two cards:
ATI Shappire Radeon HD2600XT (256MB)
Asus Nvidia Geoforce 6600 (356MB)

The ATI is in the first PCI express device, the Nvidia to the second PCI express:

lspci | grep VGA
01:00.0 VGA compatible controller: ATI Technologies Inc RV630 [Radeon HD 2600XT]
04:00.0 VGA compatible controller: nVidia Corporation NV43 [GeForce 6600] (rev a2)

So I have used this Xorg configuration file (if I let Xorg to configure without the configuration file, it sets NVidia to default card and X files to start):

more /etc/X11/xorg.conf

The Nvidia driver were installed as described in some forum:

1) disabling nouveau in grub configuration

kernel /boot/vmlinuz-2.6.31.12-174.2.3.fc12.x86_64 ro root=UUID=a5d981b4-0ff7-4453-9d61-ef40487d829e  LANG=it_IT.UTF-
8 SYSFONT=latarcyrheb-sun16 KEYBOARDTYPE=pc KEYTABLE=it rhgb quiet rdblacklist=nouveau

2) Take SElinux to alow the driver:

setsebool -P allow_execstack on

With this, the driver is correctly loaded in memory:

lsmod |grep nvidia
nvidia               9624568  0
i2c_core               28976  2 nvidia,i2c_i801

but the Xorg says that not Nvidia Driver where found (see the attack file).

These are the NVIDIA driver installed:

rpm -qa | grep nvidia
xorg-x11-drv-nvidia-libs-190.53-1.fc12.x86_64
kmod-nvidia-190.53-1.fc12.1.x86_64
kmod-nvidia-2.6.31.12-174.2.3.fc12.x86_64-190.53-1.fc12.1.x86_64
kmod-nvidia-2.6.31.9-174.fc12.x86_64-190.53-1.fc12.x86_64
nvidia-settings-1.0-3.2.fc12.x86_64
xorg-x11-drv-nvidia-190.53-1.fc12.x86_64
nvidia-xconfig-1.0-1.fc12.x86_64

What can I do to make NVIDIA driver to work?

Thanks

Blacklisting ATI ? Radeonhd IIRC.

Here the blacklist.conf:

cat /etc/modprobe.d/blacklist.conf
#                                                       
# Listing a module here prevents the hotplug scripts from loading it.
# Usually that'd be so that some other driver will bind it instead,  
# no matter which driver happens to get probed first.  Sometimes user
# mode tools can also control driver binding.                        
#
