[SOLVED] Priviledge problem

[Hansvon]

I've updated my F16 laptop to F17 using yum.
It's working almost OK except my account has no priviledge:
- I can't try to connect to another wirelss network
- it seems pulseaudio (for example pavucontrol or the gnome control) doesn't see the sound card (as root, "alsamixer -c0" sees it; as standard user, I can only see pulseaudio)
- in the gnome settings, I can't give the root password to create a new user for example (it's locked)
- ...

It happens in gnome-shell, cinnamon and XFCE. ConsoleKit is removed.
I can see strange messages in .xsession-errors

I especially wonder about the first message. Which pam file cannot be read?

I've tried to reinstall pam, create a new user, add my user to the wheel group... No success... I have also installed the Base and Gnome Desktop Env groups...

Any idea?

I've found what was wrong:
systemd, pam and polkit were installed twice (x86_64+i686). Don't know why the i686 packages were pulled when I did the 16->17 update...
