Quadro FX 3400 PCI-E not swapping buffers?

[siersmak]

I've got the following configuration, built on the nForce Professional 2200 chipset:

dual 250 Opterons
8 GB RAM
Nvidia Quadro FX3400
250 GB SATA HD

I've installed Suse 9.2 x86_64 on this machine, with the X86-64 NVIDIA driver version 1.0.7174 installed. If I pass the 'noapic' option to Grub, I can start X windows. Hardware acceleration is enabled, but some of my OpenGL apps are behaving strangely. glxgears reports around 15000 FPS, which is great, but the apps that behave strangely appear that they are not consistently swapping buffers. Basically, the app draws the scene normally for a period of time, then it will suddenly stop drawing the scene -> the first sign of trouble is that the scene will get corrupted (it appears that there isn't enough video memory, even though I am certain there is because it looks fine on cards with much less memory). If I resize my app, the app begins drawing the scene normally again.

This is not exactly repeatable, but it happens frequently enough to be a problem.

I have never had this problem on any of my AGP NVIDIA cards. Was the PCI-Express a bad choice??

I hope someone has some advice for what I can do.

Thanks,
Ken

I've narrowed down the problem quite a bit since I posted my original vague post.

I'm getting Xid errors on this card, seems similar to http://www.nvnews.net/vbulletin/showthread.php?t=49117, but on a PCI Express Quadro card. Usually, the problem will manifest itself as my app simply failing to redraw the scene correctly, and it will return to drawing correctly if I resize my app. On occasion, X will lockup with these Xid errors, and I'll have to login remotely and reboot the machine. Here's myore information about my system:

dual 250 Opterons
8 GB RAM
MOBO: nForce Professional 2200 Chipset
Nvidia Quadro FX3400
250 GB SATA HD
Suse Linux 9.2 X86-64
Kernel 2.6.11-7
NVIDIA graphics driver: 1.0-7174
NVIDIA NFORCE driver: 1.0-0301

Here's my most recent bug report...

Hi siersmak, unrelated to your problem - have you tried using your FX 3400 with pseudocolor overlays? I wonder if this card can do the advertised full 8-bit deep overlays, not 5-bit (as the lower-end Quadro FX 500 that I've tried does). I'm trying to find out if this is a driver issue common to all cards or a hardware limitation on that one card.

If not too much trouble, could you set the following options in your xorg.conf (or XFree86.conf), in section describing the card:

Option "CIOverlay" "yes"
Option "OverlayDefaultVisual" "yes"

then start X server in 24-bit mode and run xdpyinfo? (I've just asked another guy with FX 4400 to do the same.)

Thanks in advance
Maxim
