Recently I've been checking my log and found two weird errors which I don't understand.The first one:May 22 08:11:00 localhost dbus: [system] Rejected send message, 1 matched rules; type=method_call, sender=:1.25 (uid=42 pid=2827 comm=gnome-power-manager) interface=org.freedesktop.Hal.Device.LaptopPanel member=GetBrightness error name=(unset) requested_reply=0 destination=:1.7 (uid=0 pid=2155 comm=hald))qThe second one (this one repeats a lot):May 22 16:14:55 localhost NetworkManager[1991]: <warn> error requesting auth for org.freedesktop.NetworkManager.enable-disable-wwan: (6) Remote Exception invoking org.freedesktop.PolicyKit1.Authority.CheckAuthorization() on /org/freedesktop/PolicyKit1/Authority at name org.freedesktop.PolicyKit1: org.freedesktop.DBus.Error.NameHasNoOwner: Remote Exception invoking org.freedesktop.DBus.GetConnectionUnixUser() on / at name org.freedesktop.DBus: org.freedesktop.DBus.Error.NameHasNoOwner: Could not get UID of name ':1.49': no such nameDoes anyone know what those mean?
