Default Possible Graphics Card Problem on Ubuntu 6.10

This is a post I made in the Windows Forum section, which I think could also be addressed by the community here in the nVidia Linux Forum:

Title: Possible Graphics Card Problem on XP
Msg:
I have an nVidia GeForce4 MX 440 card. Whenever I browse the Internet (using XP), I often find my PC either crashing or hanging still often when I visit a webpage requiring flash (which is virtually most websites). I have tried to reformat my PC and all but no luck. I also tried reinstalling, updating, and even downgrading my Flash Player but it didn't solve anything.

I don't know if this will help, but my PC (which also has a Linux Ubuntu 6.10 Installed) also hangs and crashes in a similar situation under the Ubuntu 6.10. However, with the proprietary nVidia driver uninstalled, my computer doesn't crash. So, I thought maybe my graphics card is the problem.

Is this so? If yes, does anyone know how to fix it?

It doesn't have to be the video card. Especially in this case. Don't be fooled by the fact that it's only happening with the graphics driver installed. The hardware video card driver usually involves more complex instructions due to the fact it have performance in mind compared to the 'nv' driver. Things like the Render extension, which is the one thing I would suggest you try to disable first.

Also be sure to do a memtest86 (should be in grub or on your installation CD).

Last but not least try to set your AGP rate lower (eg. 1x and move up from that). You can read about changing that in the readme file.

How is reading the "If you have a stability problem, PLEASE read this first" post not a solution to your problem?

It's documented in the README file.

But first you could try and set it in the system BIOS.

Lithorus,

Thank you very much! I changed my AGP rate in my system BIOS from x4 to x1, and currently, I'm not experiencing the problem anymore. Thank you again!

May I just ask what does the AGP rate do?

Thank you again! You helped me solve my age-old problem.

Sometimes my pc freeze again, this is a little section of my xorg.conf:

Code:
Section "Device"
    Identifier     "NVIDIA Corporation NV18 [GeForce4 MX 4000 AGP 8x]"
    Driver         "nvidia"
    Option         "AGPMode" "4"
    Option         "NvAGP" "2"
    Option         "NvAGP" "0"
EndSection

it's necessary that i change agp rate in bois settings?

i work with windows, non only with ubuntu, and win works well with nvidia driver...

Glad you got it working
AGPRate is the speed of AGP port. The latest agp cards can support 8x, but since the communications involves not just the graphic cards, but also the chipset/motherboard there can be incompabilities. AGP seems to have been haunted by a few incompabilities and I believe it's due to that fact that it has evolved while beeing used. Eg. AGP started at about 1/2x and ended up with 8x in the latest version. PCI express have from the beginning started on 16x which seems to hold for quite some time. Not even sure that current chipsets can saturate all the bandwidth in practice anyway.
