Re: [LAU] Hard lock-ups -- Trying to narrow the cause

Hmmm.......did my reply to Drew go to just him? This gmail sort-by-subject thing can get weird. Anyway, I wanted to make sure my symptoms were included in this as well, so here it is: Great thread. I've been having intermittent lockups on my machine since I installed UbuntuStudio on it about 8 months ago. Started on Hardy. Now on Intrepid. It took me so long to get Compiz working with my Nvidia GeForce FX 5200 that I don't want to even think about moving to Jaunty. I've ran memtest at least 3 times now with no errors being returned each time. I used to think it had something to do with a screensaver (and the nvidia driver) but I don't think that's the case. I've been sitting in front of it while it's happened and it usually goes like this: 1. usually Firefox dies (last night it happened when I viewed a myspace page so it almost seems like a Flash issue) 2. the screen goes blank (black) 3. my mouse cursor turns into the spinning cursor although I can still move it for a few seconds (10-15 or so seconds, I'd say) 4. finally, a 100% freeze although I can still see my router/hub blinking so it looks like there is network activity Then I have to do a hard restart. Funny thing as sometimes it won't happen for a couple of weeks and I'll think, "Sweet! It's fixed!" Then it'll happen twice in a day. Can't imagine that it's good for the hard drive with all these hard restarts. I have a mac laptop sitting nearby though. I'll try the ssh bit when it happens and maybe I can figure something out.
