Hi-<br>
<br>
Thanks for your responses. I will try to answer in one rather than individually.<br>
<br>
I have a Dell M2400 laptop, Nvidia graphics card (<a href="http://dell.to/fqyD5M" target="_blank">http://dell.to/fqyD5M</a>).<br>
I run updates regularly.<br>
I am currently using the proprietary nvidia graphics driver.<br>
I was using nouveau previously but suspend wasn't working with it.<br>
<br>
The key to the problem is it affects all other processes and it doesn't go away by simply killing a specific process. What happens usually is I kill or stop firefox-bin, plugin-container, chrome and all other apps until the CPU calms down completely. However I can't start any new apps (e.g. nautilus) without seeing the CPU go to steady 100% for 10-15 seconds even for simple things. The only way out is to shut down and reboot.<br>
<br>
Because of this pattern it makes me think there is a bug in some lower-level service (like accessing the file system or graphics) that applications rely on but I'm not sure how to pin it down.<br>
<br>
I will try to look out more for patterns but it happens a lot when watching flash video (e.g. <a href="http://parleys.com" target="_blank">parleys.com</a>) for extended periods of time, sometimes when using skype video. Recently I noticed a fairly isolated case when running a CPU-intensive Java build process (no browsers open at all).<br>
<br></blockquote><div><br>That is very similar to my problem: both Flash and Java apps caused exponential CPU usage. Shutting down everything would cause the machine to settle down but it wouldn't become stable until a full reboot. I would suggest checking to see if there's a BIOS update for the machine as I've just done that and it's seemed to resolve the heating issues that I had that apparently came from the Nvidia GPU. Also you don't mention the version and architecture of Ubuntu that you're using which might be useful to know.<br>
