Re: how to disable monitor goes into sleep mode

It's quite possible that your monitor does it all on it's own. I don't think linux does this but if it did, it would be in the power management options within the kernel. You'd probably need to re-build the kernel without power management. As I said though, it probably is the monitor that is doing it.
Never preceed any demonstration with anything more predictive than "watch this"

Re: how to disable monitor goes into sleep mode

Unfortunately, this *IS* a kernel thing.

The monitor (as far as I'm aware) doesn't go into sleep mode unless APMd is running, but it does 'blank' after 10 minutes of no action.

It's not an easily configurable option, and I'm not sure if you can stop it from doing it, without a real kernel hack.

(I beleive it's the line:

static int blankinterval = 10*60*HZ;

in drivers/char/console.c)
