Default ANY working 8x AGP card?

I have not seen any reports of successful installations of any nvidia 8X AGP card with linux. Has anyone been able to achieve this goal? I am presently using Mandrake 9.1 and I have had miserable luck trying to get any nvidia card that supports 8x AGP to work with linux.

Has nvidia quit supporting linux?
What Gives?

Thumbs up AGP rate

On RH9.0 and a PC with AGP 1x/2x and a chipset Intel 82440LX
and a GeForce4 MX440 8x card I figured I fell into the category
of your conclusion. However I wasn't looking for fast 3D graphics,
strange enough I got this card for tv-out (I know I should have got another card ..) However even with the AGP disabled, TV-OUT can
still be made working:

After changing the Option "NvAGP" to "0" I was able to use TV out

Also for the sake of it I also included:
options nvidia NVreg_ReqAGPRate=1
options NVdriver NVreg_ReqAGPRate=1
into my /etc/modules.conf but guess this is not needed
Also read the README with the driver code to see how you
can change the c-code to also force the AGP speed down.

With the following settings in the XF86Config the TV is
showing my monitor screen 1:1 (bulding a mediastation...):

Section "Device"
Identifier "Videocard0"
Driver "nvidia"
BusID "PCI:1:0:0"
Option "NvAGP" "0"
Option "TwinView"
Option "TwinViewOrientation" "Clone"
Option "MetaModes" "640x480,640x480;800x600,800x600"
Option "TVStandard" "PAL-B"
Option "ConnectedMonitor" "CRT,TV"
Option "TVOutFormat" "COMPOSITE"
Option "SecondMonitorHorizSync" "30-50"
Option "SecondMonitorVertRefresh" "60"

EndSection

I agree all is very unstable with AGP & with this driver,
quite sad if you got the card and want to play qa,ur or hl2
on linux.

Perhaps the real kernel tweakers can debug the .c code from
nVidia I noted it all ends when the AGP stuff gets addressed, the PC
then comes to a full stop. Hints are in the direction of the NvAGP flag...
0 : disable agp
1 : use NVIDIA's internal AGP support, if possible
2 : use AGPGART, if possible
3 : use any agp support (try AGPGART, then NVIDIA's AGP)

My FX5900 Ultra seems to be working fine and bios is locked to AGP x8, can play quake3, UT, UT2003 no problem.

SuLinUX:
Which version of linux are you using?
and what kernel version?
Did you have to load any special agp
drivers?
I am so excited to hear that someone has
a working card in linux at 8x speed!

Also what manufacturer made your video card? I.E. eVga, XFX, PNY, MicroStar?

Have a look at my SIG, my FX5900 Ultra is a PNY and I am running the 2.4.20-38 kernel which came with Suse 8.2.

I installed the Nvidia driver off Suse update and games run just as good as windows, I can even use FSAA and Anisotropic filtering.

Does your ASUS motherboard have
the on-board sound option, and does
it work fine in linux? I noticed that you added
a SB Audigy how does that work in linux?
And did you ever try the on-board sound
before installing the audigy?

In fact what options do you have on your
motherboard? I.E. lan, sound, raid, 1394,...?

I just realized something. My computer was
running an AMD Athlon XP 2700+ cpu which uses the DDR 333 memory speed not the DDR 266 speed. I wonder if this is where the problem starts? Does anyone know of a motherboard video card combination that works with the cpu memory bus running at DDR 333 and the video card running at whatever speed it runs at to use AGP 8X with internal DDR video memory?

Hi all

I successfully use agp8x on my computer.
My card is a GeForce 4 Ti 4800 SE 128MB, manuf: Point of View.

Barry Mead noted that he might have problems to get agp8x working due to DDR timings, I don't think that is the issue, because my system runs with 400MHz DDR in DualDDR mode, or maybe I misunderstood him.

I use nvidias agp driver, as linux built in driver lacks support for my nForce2 chipset.

To be able to use nvidias AGP driver you must have AGPGART compiled as a module (or not included at all) in the kernel, and ensure it is not loaded.
You should also place this line in your XF86Config file:

Code:
    Option	"NvAgp"			"1"

/proc/driver/nvidia/agp/ shows this
Code:
bash-2.05b# cat status
Status:          Enabled
Driver:          NVIDIA
AGP Rate:        8x
Fast Writes:     Disabled
SBA:             Disabled
bash-2.05b# ls
card  host-bridge  status
bash-2.05b# cat card
Fast Writes:     Supported
SBA:             Supported
AGP Rates:       8x 4x
Registers:       0x1f000e1b:0x1f004102
bash-2.05b# cat host-bridge
Host Bridge:     PCI device 10de:01e0 (nVidia Corporation)
Fast Writes:     Supported
SBA:             Supported
AGP Rates:       8x 4x
Registers:       0x1f00421b:0x00000102
As you can see SBA and fast-writes is not enabled on my system, as I havn't bothered to enable it yet.

To enable SBA and Fast-writes you have to pass
NVreg_EnableAGPSBA=1 NVreg_EnableAGPFW=1 when loading the nvidia module, or insert this line in your modules.conf:
Code:
options nvidia NVreg_EnableAGPSBA=1 NVreg_EnableAGPFW=1
When you start X, if you get to a black screen or a text screen with a lot of senseless garbage in every color of the rainbow, you have to disable acpi for Nvidias driver to work. You can do this by passing both pci=noacpi and acpi=off to the kernel when booting. This solved this issue for me and others. XFree's nv driver does not suffer from this problem.

Good luck =)

I use a Geforce FX5600 and SuSE Linux 8.2 with kernel 2.4.20-100

I was luck, a quick look at /proc/driver/nvidia/agp/status told that I'm running my card at full speed, 8x !!!

Fast write and SBA are not enabled tough...

I think my AGP slot is only 4x, but my Ti4600 is 8x and works wonderfully. I'm using the kernel's AGPGART rather than NvAGP. NvAGP also worked, but was slower for this particular motherboard.

Thumbs up GeForce 4 MX 440

works for me -
Debian sarge - kernel 2.4.21 customised
with a no name video card.

I must mention that I don't use it at 8x as I don't have an 8x AGP port (only 4x - Abit kt7a motherboard - kt133a chipset).
