For those that apparently don't want to google for the system specs,
there's the HP product page

I guess I hadn't realized that SSH would be down by default in Ubuntu,
so I could retry the test...but Ping doesn't work either, so my guess
is complete system lock (no way Ping reply is disabled at default is
there?).

I'm leaning toward a kernel issue with the older hardware. It's a P4
system 1.8ghz (I think).

>are you leaving web pages with flash open?

The only web page left open is google documents, so no, no flash
content. When I left it last night, google docs was the only thing
open.

>how nuch swap and ram do you have?
1 gb of ram. I just let Ubuntu partition the swap automatically.

Video card is an Nvidia GForce 2 MX. I don't know if it matters or
not, but the processor on the video card was pretty darn hot even
though the system's been sitting frozen for hours.

I just pulled the yamaha sound card. Just in case. At the moment, I
have no need for sound anyway, but I will want to change that in the
future.

I just had it lock again. SSH is locked out too. Its a complete
system lock.

It does appear though that it's trying to go to the screensaver, and I
thought I had that shut off. So, I'm going to investigate that a bit
more. However, yesterday it was locked and it definately was not on
the screensaver.

I think I decided yesterday that being with or without the screensaver
wasn't changing anything. So, I enabled it again, while leaving all
of the power management off. I have again disabled it now, and I am
still leaving the power management off.

It locked this time after approximately 45 minutes between testing.

I'm having the exact same problem. Mostly Ubuntu freezes (total system
lock, no mouse, no kb) when "left alone" for a few minutes, but a
couple times it froze right on my face, during use.

My specs are a Core2 Quad Q6600, 8GB RAM, NVIDIA 8600 GT. Main
partition is 45GB ext3 and swap about 2GB.

Have tried completely removing compiz libraries, with no effect, so I
guess it's not a video problem. The weird thing is that 9.04 worked
perfectly on this machine.

I'm clueless.
