Hi all, I have installed the ultimate version of Kubuntu (Dapper Drake flight 2) shipped with kde 3.5.
The installation end without problem but when I log in the first time and try to log with superuser (in control center to modify some configuration or in program whic need the super user privilege) the log in fails (the error is: wrong password).

Note that via kconsole the command "su" works correctly.

I have posted the same question to Kubuntu forum. I don't know if this is a KDE problem or a Kubuntu problem.

Regards

You're using your own (user) password? Because officially there's no thing like a root login in Kubuntu.

Yes, I'm using my own password (I have choose the password during the installation of kubuntu), the system have the password saved correctly because I can login as superuser(using "su") from console but not from superuser login box in [KDE]

.

Note: I have enabled the shadow password option but I don't know if without shadow password there is the same problem

I had a similar problem and was very frustrated. I never really fixed it because it was a fresh install of kubuntu - instead I did what I had done on my other linux box, which was install Ubuntu, then install KDE as described here

But this isn't a great option, I'm sorry I can't be of more help, I know there were posts about this on the Kubuntu boards, with some pretty irate people (with decent reason, it was very frustrating).

The installation is fresh

Also my installation is fresh. And the other problem is that after some reboot Grub crash (with error 27)! and I can't access to the pc without a live cd or windows cd!!

The reply of my post in Kubuntu forum was "use kubuntu 5.10 and not the lastet version if your are novice in kubuntu fields!"

OK. I have installed KDE 3.5 (with Kubuntu 5.10) and all is ok. When Kde need a "su"
password insert YOUR password because Kubuntu disable su root access and execute the command wich need super user privilege with the command sudo.
You can enable the normal access with "su" reading the Ubuntu Wiki post indicated in the previous post of this thread.

Now I have to try to do the same with Kubuntu 6.04 (last snapshot) and inform you about the result

After a brand new Kubuntu/Ubuntu install, you have to set your root password (from a console) with:

	Source code
1	sudo passwd root

You will be prompted for a password.

It is not usual to log in graphical mode on a Linux system, the vulnerability is almost as high as on Windows systems if you do so. Even in console mode, you might use the root account only if there's a really good reason for doing so.

For administration purposes, use su or sudo in a console, that's the secure way to do it.

If you're enough foolish to you insist on a graphical root login, you have to edit the file /usr/kde/3.x/share/config/kdm/kdmrc. Look out for the line
