I hope i'm not asking once more time a frequently asked question, but i just can't find any topic about my problem.
(And I'm sorry for my english, I'm french)

I've created a non-root user with the 'adduser' program.
When I launch a graphical interface ('startx'), there is no way for getting the root theme (with dragons in the menu).

There are 'Dust','DustSand', 'New Wave' (~the root theme) as choices in the Appearance Preferences.

with 'ls /usr/share/icon' i can see more folders the these three and the 'bt-icons' folder is reachable (not 'root locked')

Any idea ?
