[UniMacTech] Shutdown when login window is idle.

[Kristien Clayton]

Dear Kai...

We used to do something similar in Physics, but instead we would  
trigger the screensaver when the login window was idle--it was eye  
candy for passers-by during idle lab times.

I started writing the screensaver script myself, but then I got lazy  
and searched the Web. I found one approach that worked spiffily with  
our 10.3 systems. The script is driven by cron (or by launchd, I  
suppose, if we were running it on Leopard machines). Here's the site,  
which appears extant:

http://homepage.mac.com/gregneagle/iblog/C1833135211/E1305475742/

I suppose you might merely want to issue '/sbin/halt' in place of the  
screensaver in the script from the above site. I've only ever invoked  
ScreenSaverEngine.app using this method, and I've only ever used it on  
G3 iMacs and on eMacs running Panther.

Regards
Kristien
