Default Stability problems with one portrait and one landscape dual monitors.

Hello,

I have a Quadro FX 3450/4000 video card using Nvidia drivers 185.18.36 and kernel 2.6.30 on Debian Lenny. The only nonstandard thing about my setup is that one monitor is landscape (1680x1050) and the other is portrait (1024x1280). The nvidia configuration tool does not allow this setup, so I have had to write the xorg.conf manually.

Frequently (i.e. about once per hour, more if I am watching video) the machine will completely lock up. In this state, the mouse will move but it will not traverse the divider between the screens, and the capslock key will not cause the LED to light. After 10-15 seconds, the machine unfreezes and I can continue is normal. NVRM errors appear in dmesg after this event.

Attached is an nvidia bug report log generated after the issue has occurred, with the xserver at -logverbose 6. I forced the issue to occur quickly by watching fullscreen Flash video, but that is not the only way to cause it to freeze (often it does it without any particular load).

I hope this issue can be fixed! Please let me know if you need any more information.

Is this one of those NForce3 AGP chipsets?

The card is PCI Express. I don't know what chipset it is, but if you tell me how to find out I would be happy to provide you with that information.

Hi -
Could you post a copy of your xorg.conf? I will try and work through this with you.

Hi, Scott,

My xorg.conf, as well as a large amount of logs and other information that may be useful, is already included in nvidia-bug-report.log.gz which is attached to the initial posting. Here it is again for your convenience.

Thanks for your help,
Arren
