You can see here what happens when you leave the computer on at night:

on a more serious note: if you have access through ssh from another computer
you could "sneak" in and check with top or ps what's going on.
Or just use a blank screen for a a scre     ensaver.
Or... make a little script that grep's for you screensaver in the process 

#! /bin/bash
while test 1 = 1; do
  date +%Y%m%d-%T >> ps.log
  ps -A | grep -i [name of your screensaver] >> ps.log
  sleep 10

(I'm not sure if the script would be working out-of-the-box, most likely you 
will have to finetune it).

Gruß & Happy Holidays
