Unable to start the settings manager 'gnome-settings-daemon'.
Without the GNOME settings manager running, some preferences may not take effect. This could indicate a problem with Bonobo, or a non-GNOME (e.g. KDE) settings manager may already be active and conflicting with the GNOME settings manager.
Today, I got it when going to Control Center/Appearances to choose a GTK theme. I don't use KDE and don't know what could possibly be running that would be conflicting with it. Any ideas what I can do about it, please?
