Ubuntu Shuts down (almost ?)

[Gordonisnz]

Hi,

I've got a problem, & i'm not sure how to find the cause...


Every now & again, my Ubuntu machine shuts down - Screen goes blank, but PC is still "on".)

I'm running WINXP / LInux on 2 boxes - Using Synergy between them...

My synergy connection is closed/shut, & if I press a key on my Linux/Ubuntu box - Nothing happens.

Its only started tonight/today. & if I press a key on my linux box - It doesn't 'waken' (as if it was asleep)..

Its completely shut - But my linux PC box lights are still on..


QUESTION :- Is there a setting I can do, to "log" these shut-downs ?


QUESTION :- Does anyoneknow / think of somewhere I can even start to diagmose this


- I can't use the Keyboard - Nothing happens...

The only way I can turn it on, is to turn off - Then on again..


Any ideas welcome.

Thankyou

Hmm

Its happened twice tonight...

Looking for "sleep" or "shut down" - But as yet, I can't find why its closing the PC

(it is still "on" - PC lights are on, & screen light is on ..) - But screen is black & wont "wake up"

You might try looking in the logs for pm-suspend.log and messages at/or around the time it happens, if you are correct about it sleeping there might be something there.

Have you tried the magic sysrq key?
