Default Re: Random crashes, NVRM Xid messages

I have also disabled all the relevant plugins from gkrellm, in order to prevent such modules from being loaded automatically.

The system is rock solid now, running for 2+ days straight under KDE+composite without a single glitch.

I suspect that some such program or kernel module is periodically polling/generating interrupts under nvidia driver's nose, messing up the interface. It would be nice if someone could debug this to the end, though.

Hope this helps,

Nice find!

In my system i have loaded two modules for sensors and then there's the nvidia built-in thermal and frequency monitor.

It looks like disabling the Thermal Monitor in nvidia-settings configuration is enough! (GeForce GT240 with 304.43 and linux 3.2.0-31-generic)

I need to do further testing though
