Hi!

I used Gnome till now and I wanted to chk out KDE too so I installed the kubuntu-desktop package. KDE works perfect expect for a little problem.
I cannot do anything in the control panel that needs a root passwd. I enabled the root account a long time ago: sudo passwd etc etc etc... now I can use su that I like.
Unfortunatelly when trying to use Admin mode a window pops up that su returned with an error.
I tried to disabel the root acount: root login and then passwd -l command
KDE still did not work. How can I solve the problem than??

Take a look here for a possible solution.
