If you can see it, but it's not there, it's virtual. 
If you can't see it, but it is there, it's hidden. 
It you can't see it and it isn't there, it's gone.

with older kernels 2.0 you could find the source fora nice program called
setvesablank, but i think also setterm could fit your needs

the userspace solution is simply `setterm -blank 0'

if you dont want setterm, I wager it just uses an ioctl to set the
appropriate option.

if you want to disable it permanently, take a look around
drivers/char/console.c

there is a
static int blankinterval = 10*60*HZ;
setting that to 0 should do the job.  you could take it further and rip
out some of the *blank* functions that you wont be needing, to make your
kernel smaller.

Hi,

I am on a 2.2.19 kernel. I am doing an embedded box and I want to disable
the console blanking ... how can I do that ? I dont have apm support in the
kernel. there is no X on the box ...
