how to disable autologin in Mandriva 2010 Live
 

Hi, This may sound like a trivial/childish question but I need your help.
How do I disable the autologin function in Mandriva 2010 Live, 32-bit distro?
I tried the Linux Control Center/Security/Configure system security and I selected 'no" in "allow autologin".
The system still logs in to one user automatically.
Then I tried the Configure Your Desktop icon in the kicker panel.
There is a Login Manager (KDM) option in Advanced tab. I clicked on it and in the Convenience tab I saw Enable Autologin checked.
I can only disable it when I'm Root.
Please, remind me how I can run this as Root. It completely escaped me.
thanks

I solved it myself. It's been a while since I've done it LOL
it's as simple as typing KDM (that's' the Login Manager) in the run line
The system asked me for a root password an voila!
