FreeBSD的屏保也是做成ko模塊的，默認是不加載的，可以手動加載進去就可以啟動屏保:
#cd /boot/kernel
#ls *saver* |grep -v symbols
apm_saver.ko
blank_saver.ko
daemon_saver.ko
dragon_saver.ko
fade_saver.ko
fire_saver.ko
green_saver.ko
logo_saver.ko
rain_saver.ko
snake_saver.ko
star_saver.ko
warp_saver.ko
#kldload logo_saver
#kldstat
5 1 0xc2c21000 2000 fire_saver.ko
blanktime="300" # blank time (in seconds) or "NO" to turn it off.
saver="NO" # screen saver: Uses /boot/kernel/${saver}_saver.ko
在這裡也可以設置屏保的名字,如果把blanktime="NO"就會關閉屏保
