How to avoid power saving mode?

[laxmi_p]

Hi All,
I work on Ubuntu 9.04 and our application requirement is not to go to power saving mode when application is running. I added ServerFlags section to /etc/X11/xorg.conf
Section "ServerFlags"
Option "blank time" "0"
Option "standby time" "0"
Option "suspend time" "0"
Option "off time" "0"
EndSection

This didn't help.
Then I tried following commands
gconftool-2 -s /apps/gnome-power-manager/ac_sleep_display --type=int 0
gconftool-2 -s /apps/gnome-screensaver/idle_activation_enabled --type=bool false

I see that it works fine only if I change settings via Settings>ScreenSaver>Power Management in gnome. I wan to do this via script. Can I do this? Which file gets updated when I change display settings via Settings>ScreenSaver>Power Management.
Immediate help would be highly appreciated.

Thank You

laxmi_p, try looking into the xset command.

Maybe this might be your answer.

 xset -dpms

I found the solution !
When I change settings via Settings>Screensaver>Power Management in gnome, it edits %gconf.xml file under .gnome/apps/gnome-power-manager/timeout for display and computer sleep changes.

If the above folder doesn't exist we need to create it and then run following commands -

gconftool-2 -s /apps/gnome-screensaver/idle_activation_enabled --type=bool false
gconftool-2 -s /apps/gnome-power-manager/timeout/sleep_computer_ac --type=int 0
gconftool-2 -s /apps/gnome-power-manager/timeout/sleep_display_ac --type=int 0
