Hello again,

I think I've determined the culprit - sort of.

It wasn't the power supply...  $200 wasted.

I used to run xscreensaver with the opengl photo-panning applette.
I was sitting around cogitating, watching the screensaver pan over a photo, 
and the box rebooted.
I checked the schedule - it wasn't recording at the time.

So I disabled xscreensaver - and thereby "fixed" the reboots.

It's now been up for nearly 48 hours, which hasn't happened for weeks - it 
got to the stage where it would last 2-3 hours at most.

So of xscreensaver is causing the box to reboot (As JWZ says, there is 
nothing in xscreensaver that should cause a problem with X, (let alone a 
reboot)) - this means it's probably the nVidia blob right?

I'm using a motherboard with an on-board nvidia 9400 GPU.  The drivers are 
the Ubuntu module shipped ones "+updates".

Maybe I should change to the latest manual nVidia drivers ?

What do you think ?


thanks,
-kt
