Default Status on stability problems?

I have been suffering from stabliity problems using my Geforce4 MX440 on Ubuntu 6.06 and have tried everything to resolve it with no luck. I have exhausted the amount of time I am willing to spend troubleshooting this problem and would like to know what the status is on a definative resolution. I am suffering from what has been described as the "screen is frozen, but mouse still moves bug".

Have these sorts of problems been been attributed to a known cause?

If so, what is the cause(s)? Is there a workaround?

Do these problems occur on only older hardware such as mine? I am considering a new card anyway, and this would influence my decision.

Any information that leads to some sort of close-ended, semi-concrete answer such as "We are aware of the problem and working on it" or "We just don't know yet, but we haven't had a report of/can't recreate this on X model cards on X distribution with X version of driver" would be great.

Please generate and attach an nvidia-bug-report.log immediately after experiencing this problem.

Thanks,

I have the same problem with my Video card Geforce 2 MX400. I'm using Linux Slackware 11.0. When I replace my 'nv' with 'nvidia' on my Xorg.conf, X boots up. Once I'm on x, x freezes, but I can still use the mouse. As of right now, I have 'nv' on my xorg.conf waiting for some updates. Any suggestions in what I should do?

Same here. But only after a while. Sometimes it's days, sometimes hours till a freeze.

Just sent an email to nvidia:

"I am having massive freezes since upgrading from SuSE 9.3 to 10.1 and using a
X2 CPU.

The temperatures are at normal levels. The system is still responding via ssh,
but X takes 100% on one CPU core and is non responsive. I can't even switch
to a console. The mouse can be moved though.

dmesg shows the following line:
NVRM: Xid (0005:00): 6, PE0000 0400 ff000000 0000fdfc ff0b100c ff0c0c11

A system reboot sometimes works and sometimes doesn't.

I attached the nvidia-bug-report.log. Is there any workaround for this issue?
There seem to be more people having the "mouse-moving-but-X-dead" problem.
Would a downgrade of the driver help? Any suggestion on the version?"

Does this problem persist with the 1.0-9626 driver?

I just upgraded to 8776, but I'll upgrade to the beta driver now.
Might take some time to come back to you, cause sometimes it just works for 1-2 weeks and then crashes...

BTW: Just checked the temperatures: Idle in 2D at 66-69. I'm mostly not using 3D.

Ok, 1.0.9625 seems to fix the issue. No crash for 2 weeks now (no reboot).

I'll post again, if that changes.

Default Re: Status on stability problems?

Can we get a definitive statement from an nVidia representative which answers the questions from the original post below specifically, 'What is the cause, if known?', 'What progress and understanding do nVidia have of the problem?' and 'What's the prognosis?' Just to clarify the problem statement - as I can best define it....

"Screen frozen, mouse pointer can move and X process uses 100% CPU cycles." The only solution is to restart X.

I've seen this problem in work on Sun W1100z and Ultra-20 workstations which have the AMD64 proc, nVidia chipset and nVIDIA's Quadro FX500 Graphics Card running RHEL 3.0. I've never experienced this issue with my 32-bit Lintel system. I've tried disabling APM and disabling the agpgart kernel module and using the proprietary nvgart module along with regular driver updates. I've identified and removed some triggers of the problem such as screensavers with memory leaks etc but have not resolved the root cause albeit the frequency of lockups has been reduced. I've heard the problem is due to a race condition with the nvidia_dri.o driver - gettimeofday function goes into a loop. Is that correct?

Answers to these questions would be much appreciated.

wdoyle,
There is no definitive answer as the "mouse moves but X is hung" problem is a class of problem, its not a specific bug.

If you're experiencing problems, I'd suggest starting a new thread after reading:

thanks,
