Hi list.

     We are using Scientific Linux 6 here at our office to control some 
equipment, and are struggling to keep the monitors from ever shutting off.

     Here's what I've done so far:

     run as root

     gconftool-2 --direct --config-source 
xml:readwrite:/etc/gconf/gconf.xml.mandatory --type bool --set 
/apps/gnome-screensaver/idle_activation_enabled false
     gconftool-2 --direct --config-source 
xml:readwrite:/etc/gconf/gconf.xml.mandatory --type bool --set 
/apps/gnome-screensaver/lock_enabled false
     gconftool-2 --direct --config-source 
xml:readwrite:/etc/gconf/gconf.xml.mandatory --type int  --set 
/apps/gnome-screensaver/idle_delay 43680
     gconftool-2 --direct --config-source 
xml:readwrite:/etc/gconf/gconf.xml.mandatory --type int  --set 
/apps/gnome-screensaver/lock_delay 43680
     gconftool-2 --direct --config-source 
xml:readwrite:/etc/gconf/gconf.xml.mandatory --type int  --set 
/apps/gnome-screensaver/power_management_delay 262080

     and run in a script that is triggered at user login:

     #!/bin/bash
     [ -e /usr/bin/gnome-screensaver-command ] && nohup 
gnome-screensaver-command --inhibit &
     while
         sleep 1s
     do
         setterm -blank 0
         xset s off
         xset -dpms
         [ -e /bin/dbus-send ] && dbus-send --session 
--dest=org.freedesktop.ScreenSaver --type=method_call /ScreenSaver 
org.gnome.ScreenSaver.SimulateUserActivity
         [ -e /bin/dbus-send ] && dbus-send --session 
--dest=org.gnome.ScreenSaver --type=method_call --print-reply 
--reply-timeout=20000 /org/gnome/ScreenSaver 
org.gnome.ScreenSaver.Inhibit string:"DailyDo" string:"Running DailyDo"
         [ -e /usr/bin/gnome-screensaver-command ] && 
gnome-screensaver-command --poke
     done

     Despite this radically overkill approach, the screen still turns 
off after around half an hour. I suspect that the reason is the monitors 
built in power saving features, which I believe should be prevented by 
the "xset -dpms" command, but doesn't appear to be.

     Does anyone have any ideas? Is there something that can be added to 
the xorg configuration to prevent the screen from turning off, perhaps?

Thanks
