gconf is the configuration system for GTK, and gconftool (or gconftool-2) is the application used to interact with this system. You can get help on gconftool-2 by running "gconftool-2 --help". To modify the update frequency, the command to use is: Code: gconftool-2 --set /apps/hildon/update-notifier/check_interval --type=int 10000000 Similarly to set the blink-after value (though I don't think that needs setting). Oh, and you can run all this as the normal user, no need to be root.
gconftool-2 --set /apps/hildon/update-notifier/check_interval --type=int 10000000
