It looks like slackware (or you :-) haven't installed the at_console

different ways, and I'm not sure what is upstream.

Not such a neophyte. Have a look at /etc/dbus-1/system.d/hal.conf and
change the at_console="true" line to user="username_of_you". Then
restart dbus.

Then you should be good to go.
