I have a desktop configuration in the indicator applications to choose the desktop preferences, but i dont know how to disable it.
I know i can use the blacklist in
.config/indicators. But actually i didn't manage to disable it.
I see that an answer has been found. However, I wanted to ask if this issue could have been reconciled using gconf-editor. Under Apps/gnome-settings-daemon/xrandr, there is a setting (checkbox) for show_notification_icon. After some experimentation, that seems to work on my system.
