Dbus集成调试问题

1,connectFailed:Connection Error=Using X11 for dbus-daemon autolaunch was disabled at compile time\, set your DBUS_SESSION_BUS_ADDRESS instead

Soltuion:

export DBUS_SESSION_BUS_ADDRESS="unix:path=/var/run/dbus/system_bus_socket"

2,Connection "\:1.9" is not allowed to own the service "XXXXXX" due to security policies in the configuration file

Solution:

         name ownership and sending method calls -->

    <allow own="*"/>

/etc/dbus-1/system.conf:

For local configuration changes, create a file

system-local.conf or files matching system.d/*.conf in the same directory

as this one, with a <busconfig> element containing configuration directives.

These directives can override D-Bus or OS defaults.
