Bug#518029: hp-levels: refuses to work as user without session bus

[brian m. carlson]

Package: hplip
Version: 2.8.12-3
Severity: important
File: /usr/bin/hp-levels

hp-levels complains about being run as root, but doesn't run as a normal
user.  This is on a server, so X is not running, and there is no session
bus.  hal is not installed.

hp-levels should work on a server. If it absolutely needs a session bus,
it must create one if one is not present, or depend on a package that
will do this.

As a user:
  castro ok % hp-levels
