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
