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.

I recently had problems with a new system with a nvidia 9600GT
card in it. The system would reboot or lock up completely. The
problem turned out to be the power supply.

The 500W power supply only had 24 amps available on the +12V rail.
The 9600GT card calls for a minimum of 26 amps +12V. Replacing
the PS with a 650W one that has 52 amps on +12V fixed it.

I would believe that if Microsoft was capable of writing an OS.
But so far I have seen no proof of that.

The thing is that Windows Vista and 9.04 work just fine on this
machine, so I don't believe it's a power supply issue.

The only thing decent they've ever released was XENIX, but even that was
not really written by them. It was a version of AT&T UNIX which they
have taken a license on (through Novell, I believe) and which they had
converted to work on the Intel 80286.
