I updated my location in my profile, so hopefully that makes communication easier. Thanks for pointing that out!
When you mentioned X-Windows, it made me think that maybe Compiz was the problem. The thing is, I run Compiz on my desktop, but I have compositing disabled on my MythTV box in order to avoid vsync issues. However, I do have the newest nVidia driver, 190.42, installed on both machines, whereas I had 185.18.36 up until several days ago. When I installed the Ubuntu 9.10 final release, I went to nVidia's site to get the driver and forgot that they had posted a new version. Either way, I've downgraded back to 185.18.36 and so far my system has yet to hang in the last hour or so (on either computer). I'm going to keep testing it through the rest of the week, but so far it seems like this might have been due to a change in the nvidia driver. Also, for what it's worth, I did SSH into my machine and run top from there. Most of the time compiz.real was hogging the CPU, but a couple times it was firefox. I didn't get a chance to try the same with my MythTV box, but considering the implementation of OpenGL in MythTV, I'm thinking that might have been what was tripping it up there (I don't have compositing running on that box in order to avoid vsync issues). Reading the info at nvidia's driver download page (http://www.nvidia.com/object/linux_display_amd64_190.42.html), it appears they added support for OpenGL 3.2 in that driver, so maybe that's what was causing problems? Don't close the bug quite yet, just in case it still occurs with the older driver. I'll post again in the next few days to say whether it's showed up again or not.
