Default Problem upgrading Geforce2 MX to 6800 GS AGP

Hello, I run ubuntu linux 6.10 and have used a Geforce2 MX card with the nvidia drivers very happily on various linux distributions for many years.

I purchased a Geforce 6800 GS AGP card and am having trouble getting it working.

I swapped the cards and rebooted the computer. X starts, but then all opengl program crashes. glxgears seg faults after a second or two and the game X2 hangs the whole computer.

I tried reinstalling the drivers but this made the situation worse, when starting X the system would hang, or the graphics would be scrambled (just lines and colours on the screen). I have switched back to the Geforce 2 MX and it works fine.

When x hanged on the 6800, the xorg.0.log file was truncated without any meaningful errors or warnings.

The README document doesn't really address upgrading cards. Was it naive to just switch the cards and hope for the best?

Thanks,
Luke

Please generate and post an nvidia-bug-report.log.

Hi, I couldn't run the bug report after starting an opengl program, as it hangs the entire computer. I did run it before running opengl, so here it is.

Other systems including the ones listed above include:
high pitch frequence from speakers after crash
opengl program hangs at slightly different point each time

Regards,
Luke

I have a few questions:
0) Does this reproduce with a more recent (2.6.17.x) kernel?
1) Does this reproduce if you set NvAGP to 0 in xorg.conf ?
2) Have you verified that you're using the latest BIOS for the motherboard?
3) If you boot with the acpi=off and/or noapic kernel parameters, does that have any impact?

Thanks,
Lonni

Hi,

1. it does reproduce when NvAGP is set to 0 in xorg.conf
2. I am running latest BIOS for the motherboard
3. I booted with acpi=off and it still hangs at a random spot a second or two when running an opengl program.
as for 0. (new kernel) - I am hoping not to have to upgrade from 2.6.15 to 2.6.17 unless I can help it.

Does this sound like a hardware problem, or is it most likely a software problem?

Regards,
Luke

I don't think its a hardware problem, however there are many different potential software points of failure.

Did you boot with 'noapic'?
I'd still suggest testing a newer kernel too.

Thanks,
Lonni

I tried with noapic, and also with acpi=off and then with both (noapic and acpi=off) ... same effect. I have also noticed that while the system hangs seconds after an opengl program starts, it also crashes after several minutes anyway when just using X (2D stuff).

As for upgrading the kernel from 2.6.15 to 2.6.17, I don't think that is an option until the next version of ubuntu is released, as I don't want to get off the deb package system by compiling my own.

I can't get over how difficult it is to troubleshoot this card!

Thanks,
Luke

Hi,

In xorg.conf, as well as adding:
Option "NvAGP" "0"

I added:
#from ubuntuforum
Driver "nvidia"
BusID "PCI:1:0:0"
Option "RenderAccel" "Off"
Option "IgnoreDisplayDevices" "DFP,TV"
Option "NoRenderExtension" "Off"
Option "AllowGLXWithComposite" "Off"

Now there is an improvement - when I run x2 instead of the whole computer hanging, it only seg faults. This has allowed me to run a nvidia-bug-report again.

Does this narrow down my problem?

Thanks,
Luke

I don't see a segfault in your bug report, however I do see a kernel Oops from x2. The nvidia driver doesn't appear anywhere in that Oops. I'd still like to know whether this problem persists with a newer kernel that doesn't have PREEMPT support.

It sounds like setting NvAGP to 0 along with disabling RenderAccel is what changed the behavior? Can you please confirm whether just those two changes make the difference, or if just disabling RenderAccel helps?

Thanks,
Lonni

I will test that at the next opportunity. However, X just crashed for me a moment ago. However, X actually restarted this time (it didn't take the entire system out). For the record, Xorg.0.log has the following lines:

Those messages in your X log are harmless and aren't related to the crash.

OK, I was unable to get any 3D app running with this card with kernel 2.6.15, so I put my Geforce2 MX card back in and have been using that for the last two months.

I have upgraded my OS to ubuntu 6.10 (edgy eft), which uses kernel 2.6.17, as suggested on this thread.

The geforce2 mx card works fine, glxgears runs, as does x2.

I put in the 6800 GS and now glxgears segfaults again.

I have noticed that when I do lspci, I get
"01:00.0 VGA compatible controller: nVidia Corporation Unknown device 00f6 (rev a2)"
For my Geforce 2 MX, I got the name of the card (eg nVidia Corp. Geforce 2 MX). So I wonder if I should get "nVidia Corp 6800 GS" from lspci instead of a generic unknown device? It makes me think the card is not being registered properly due to hardware/power issues?

Any suggestions?
Luke
