Can't disable Screenlock feature

[William Tsai]

I am working at a Trading company and trader does not want to have blank screen or Screen saver popped up every certain minutes.

I tried to have following command line in postinstall scripts and they aint work.

 gconftool-2 --type boolean -s /apps/gnome-power-manager/lock/blank_screen false
gconftool-2 --type boolean -s /apps/gnome-power-manager/lock/gnome_keyring_hibernate false
gconftool-2 --type boolean -s /apps/gnome-power-manager/lock/gnome_keyring_suspend false
gconftool-2 --type boolean -s /apps/gnome-power-manager/lock/hibernate false
gconftool-2 --type boolean -s /apps/gnome-power-manager/lock/suspend false
gconftool-2 --type boolean -s /apps/gnome-power-manager/lock_use_screensaver_settings true
gconftool-2 --type boolean -s /apps/gnome-screensaver/lock_enabled false
gconftool-2 --type boolean -s /apps/gnome-power-manager/lock_use_screensaver_settings false

I ran this either via root or the user who sign on the desktop and after certain minutes, the screen still goes blanks and locked.

Thanks
William
