Hi there. Just subscribed to this list, and thought I'd share a solution to a problem before I start asking about the problems I haven't solved yet. And also I'm curious if anyone has a better way to do this.
I'm running woody on a Pismo PowerBook G3, with Ben's rsync kernel... I wanted to have it dim the screen after some idle time, and then turn it back on when i touch the mouse/keyboard, which is a feature that MacOS has. I knew about fblevel for actually turning the screen off and on manually, but needed something to handle the idle timeout... So I looked at xscreensaver and figured out the following... (jwz's man page is really informative!) The script below works as a "graphics hack" for xscreensaver (though in fact of course it doesn't do any graphics at all). It dims the screen when xscreensaver becomes active, and then turns the screen back on when xscreensaver kills it. Just create the following script, and configure xscreensaver to only use this (instead of the big list of graphical things it can do). --- #!/bin/sh # the "wakeup" code trap "sudo /sbin/fblevel 15; sudo /sbin/hdparm -S 60 /dev/hda; exit" 15 # the "go to sleep" code sudo /sbin/fblevel 0 sudo /sbin/hdparm -S 12 /dev/hda # and the "continue to sleep" code while [ 1 ]; do sleep .5; done --- Note that this is not actually putting the machine to sleep, it's just turning off the screen. And it also sets the hard drive spin down timeout to 1 minute... In order for this to work I had to set up sudo to allow my user to run fblevel and hdparm as root, with no password. (See the sudo man page...) As I said, I'm curious if there was an easier way to do this... Also, I haven't figured out a way to make xscreensaver use different configs on different hosts, which would be handy since my home directory is NFS-mounted. Have fun! ...derFlieN NeilFred Picciotto fred (at) derf (dot) net
