Hi all,

I run 64-bin Ubuntu 11.04 at work (I can post specs later if needs be), and sometimes I come in of a morning and the screensaver has frozen, I can't SSH into the box, and I need to cut the power to restart it. I think it may have something to do with the network as when my box goes down, so does our little Ubuntu 32-bit 11.04 'server'.

Under OS X and Solaris I'd know where to start looking, but everything is quite alien under Ubuntu. Can anyone suggest where I should start looking?

Cheers,
Ben

The first place I'd look is the ACPI settings.

That said, I've had problems before with the screensavers themselves and had to go without.

ACPI in the BIOS? Or in Ubuntu?
Also, would anything significant be happening in a log file somewhere? I'm not sure where to look.

Erm...

...if it can wait until tomorrow I'll have a bit more brainpower to help. Right now I'm knackered. Sorry

Sorry for the dearth of posting. Just lately I seem to be having real problems with energy levels. Consequently my brain and google-fu are both very weak.

However, off the top of my head, I would start by

1. setting the ACPI to S1+S3 in the BIOS (if possible). If that doesn't help try...
2. ...booting into Ubuntu with

   	Code: acpi=off

If that doesn't work there are other possibilities but, right now, brainy no worky. Sorry

Not a problem, thanks for your advice Jim

Hardware knowledge has dribbled out my ears I think And I'm OK at using Linux, but more admin'y things I'm having to Google far more than normal, normally one search turns into three or four as I have to Google other things..
