NVIDIA: could not open the device file /dev/nvidia0 (Input/output err)

Just installed Arch64 and installed xorg, configured with nvidia-xconfig, but when it starts it fails:

NVIDIA: could not open the device file /dev/nvidia0 (Input/output error)
Failed to initialize the NVIDIA graphics device PCI:1:0:0

lspci

VGA compatible controller nVidia Corporation G94 (GeForce 9600 GT) (rev a1)

cat /proc/driver/nvidia/cards/0

model: Unknown
IRQ: 18
Video BIOS: ??.??.??.??.??
Card type: PCI-E
DMA Size: 32 bits
DMA Mask: 0xffffffff

This is on

kernel26 2.6.32.9-1
nvidia-96xx 96.43.16-1

/dev/nvidia0 exists ... but with cat it shows nothing.
Any ideas what could be wrong? (I'm on Windows at the moment, please help me! )

Already did that, and also put it in modules() in rc.conf. No luck.

Does it work if you install 195.36?

edit: Take it out of the modules array in rc.conf.  You don't need to do that.

Tried installing the 'nvidia' package, but it gives an error about "API mismatch something something".

EDIT: already tried not having nvidia in modules() array

you are using the wrong nvidia package. for your card you need nvidia and nvidia-utils.

rmmod nvidia
pacman -S nvidia nvidia-utils
modprobe nvidia

Give what you have. To someone, it may be better than you dare to think.

As I said earlier, that gives some kind of "API mismatch" error when starting X.

1. pacman -Rd your current nvidia packages.
2. install nvidia nvidia-utils
3. Reinstall xorg
4. make sure you've fully updated your system.
5. Make a minimal xorg.conf

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    Option "RandRRotation" "true"
    Option "NoLogo"        "true"
    Option "Coolbits"      "1"
EndSection

or run nvidia-xconfig

6. Reboot.

make sure you completely remove the older driver. if you still have a problem, post the error log here
