Proprietary NVidia drive makes my machine halt [Kubuntu 8.04/AMD64]

Binary package hint: nvidia-glx-new

Hi,

I have a AMD Athlon(tm) 64 Processor 3200+ with a ASUS K8N motherboard and a XFX GeForce 6800 XTreme 256MB DDR3 AGP.

I had the same system with Kubuntu 7.10 (i386) and all works perfectly. But I made the upgrade to Kubuntu 8.04 (AMD64) and, whenever I first start my machine, it's halt while loading X. When I cold reboot the computer (push the reboot button) it's load normally.

I'm sending some file to better understando my problem, if you need some test or some others files, please, call me, right?

Thanks a lot,
Alexandre

My aperture size in BIOS is already configured to 256 MB (see the dmesg-boot-normal.txt attachment). Any value brings the same result.

Adding the parameter "iommu=memaper=2" (or any other value) results machine freezing in every boot (instead of the first only, without the parameter).

Any help?

Can you add the following option to the Device section of your xorg.conf?

Option "NvAGP" "0"

then restart the Xserver (or your computer) and see if you can still reproduce the problem (both with and without "iommu=memaper=2")

Hi Alberto.

Thanks for the feedback.

Using this option, the agpgart still apper, but X don't freeze, either with and without "iommu=memaper=2". I think it's a good workaround, but I believe that we still have a problem with agpgart. Then, if you want to continue testing to find the problem, I will be glad to help.

Best regards,
Alexandre

The problem is that if you can't reproduce the problem with NvAGP 0 it means that it's likely that your motherboard (rather than the graphics driver) is what is causing the lockups.

[Alberto Milone (albertomilone)]

Maybe you could try to upgrade the BIOS and see if the problem goes away.

I checked again and my BIOS is in latest version (1011). But I remember clearly that it's work fine in 7.10/i386 version. Then, I guess it can be one of two things:

- A problem with AMD64 architecture, not present in i386 architecture
- A problem with kernel 2.6.24, not present in kernel 2.6.22

The worst scenario is if the problem is with both: kernel 2.6.24 in AMD64 architecture.

What do you think if I "graft" 7.10 AMD64 kernel and modules to see what happens? It's far less complicated than install 7.10 i386 or AMD64, at least, for while.

Best regards,
Alexandre
