[TriLUG] disabling screen blanking

I don't know about Debian in particular, but I can attest to John's claim
that it's not X that is messing with you. A text login would do the same
thing, and my guess is that it's an apm issue. Check your BIOS, and also
any apm software you may have running, for screen-blanking (or shut-off)
Hope this isn't completely off-the-wall,
