Ok, the file has been edited per your instructions. However, Fast Writes is still disabled. If it helps, here's the entry for my video card in my xorg.conf file:
Code:
Section "Device"
Identifier "NVIDIA Corporation GeForce 6200 AGP"
Driver "nvidia"
BusID "PCI:1:0:0"
EndSection
and here is the modules section:
Code:
Section "Module"
Load "dbe"
Load "ddc"
Load "dri"
Load "extmod"
Load "freetype"
Load "glx"
Load "int10"
Load "type1"
Load "vbe"
Load "GLcore"
EndSection
According to glxinfo, my drivers are:
Code:
OpenGL version string: 2.0.2 NVIDIA 87.56

1) Can you post the content of this?
sudo nano /etc/modprobe.d/nvidia-kernel-nkc
2) Did you enable Fast Writes in your BIOS?

2) Yes.
Re: HOWTO:Nvidia AGP FastWrites and Side Band Addressing
I reviewed the original Gentoo Wiki entry and noticed this:
Code:
cat /proc/driver/nvidia/agp/host-bridge
which output the following:
Code:
Host Bridge: PCI device 1106:0204
Fast Writes: Not Supported
SBA: Supported
AGP Rates: 8x 4x
Registers: 0x1f000a0b:0x00000b02
So, it's not a problem with tseliot's guide, Ubuntu, the NVIDIA drivers or the card itself, but it appears to be a problem with the motherboard's AGP interface. Even though I cannot enable Fast Writes, I found a working alternative with nvclock. I will attempt to upgrade the BIOS to see if this will correct the problem or not.
Re: HOWTO:Nvidia AGP FastWrites and Side Band Addressing
Worked for me with an Nvidia 6800nu and an Abit IS7.
Re: HOWTO:Nvidia AGP FastWrites and Side Band Addressing
Code:
cat /proc/driver/nvidia/agp/status
Status: Enabled
Driver: NVIDIA
AGP Rate: 4x
Fast Writes: Enabled
SBA: Disabled
Code:
cat /proc/driver/nvidia/agp/host-bridge
Host Bridge: PCI device 1039:0745
Fast Writes: Supported
SBA: Supported
AGP Rates: 4x 2x 1x
Registers: 0x1f000217:0x00000114
Code:
cat /proc/driver/nvidia/agp/card
Fast Writes: Supported
SBA: Not Supported
AGP Rates: 4x 2x 1x
Registers: 0x1f000017:0x1f000114
why in host-bridge output sba is supported and in card output is not supported???
i have a 3d prophet 2 mx gforce2 (nvidia-based)
Re: HOWTO:Nvidia AGP FastWrites and Side Band Addressing
Theres no agp in my /proc/driver/nvidia
lsmod shows me agpgart is loaded
whats my problem?

can you post:
1) the model of your card
2) the output of this command:
Code:
lspci -n | grep 0300
Re: HOWTO:Nvidia AGP FastWrites and Side Band Addressing
floyd@tchs:~$ lspci -n | grep 0300
01:00.0 0300: 10de:0141 (rev a2)
it's a geforce 6600 pci-e
duh
I just rembered agp are the cards that are not pci-e, right?
