How to configure kdm in KDE4 System Settings from non-root user account?


I often read that for security reasons you shouldn't start an X-session with the root accout.
Therefore I want to configure kdm in the System Settings of KDE4 from within a user account.
In KDE3 there was a button to get root in the control center and then you could configure kdm from within a user account.
The help of KDE4 also says, that there is a button to get root:

If you are not currently logged in as a superuser, you will need to click the Administrator Mode... Button. You will then be asked for a superuser password. Entering a correct password will allow you to modify the settings of this module."

But there is no Administrator Mode button, or at least I cannot find it.

Can anyone tell me how it works, or at least give me an other possibility to start the Login Manager Module of the System Settings with root privileges from within a user account X-session.

Yeah, the "Administrator" button seems to be missing in the newer versions.

However, to start any sort of application with root powers, just open a console and type:

shell$ kdesu <application-name>

The KDE control center I think is called "systemsettings" or something like that.

is it legitimate and allowed and can be done to make another user account set uid and gid to null 0 to make another root account with different name and possibly not damage the debian system creating and using that new account BenJoBoy Linux - Newbie 12 01-29-2006 11:02 AM
