Change "USER" to "SESSION". Build with: gcc -Wall -I/usr/include/glib-2.0 -I/usr/lib64/glib-2.0/include -o client client.c -lglib-2.0 -ldbus-glib-1 -ldbus-1 -lgobject-2.0 -lglib-2.0 -ldbus-1 -lgio-2.0 The again with s/client/server/ For all I know, the USER vs SESSION distinction matters, but I can't imagine why. > > That said, either you're running your test on a potato, or dbus is > seriously screwed up.
