hp-toolbox dbus initialisation error x86-64

[tonyb]

bought new multifn hp-6500a plus. Mageia asked to install hp stuff, done. HP Device Manager in tools/systemtools menu wont run. Running hp-toolbox from a terminal in a graphics session fails immediately with;
error: dBus initialization error. Exiting.

I seem to have everything relevant installed. Any ideas?

further info; just tried the same on my wife's old mandriva 2010.2 i586, urpmi hplip, it installed version 3.11.5.. hp-toolbox crashes identically with same dbus error. What is the common problem here, given that each hplip was installed from the correct repository?

To answer my own question, I think it works fine as a user, but not as root. Not a bad thing...

How did you get root? Normally this dbus error comes if you only do "su".
But you need to do "su -" to initialize a full environment, cf man su
