screen blanker?

[Tom Neff]

By the way (to atone for my bogus 'screenblank.sh' silliness) somebody
DID write a UNIX screen blanker a while back, but I have *no* idea what
it was called.

You could write your own.  The idea is just

 * have a list of tty devices to check

 * periodically scan their access and modify times

 * when a tty goes "old" send it display-off (ANSI)

 * when a tty goes "new" send it display-on

There are various refinements you could make.  It should work for the
console at least.
