I'm using openSUSE 11.1, with KDE 4.1 and kdesu doesn't accept my root password. Originally I had installed it with the root password being the same as my user, but I have since changed it (as I can login just fine from the command line) and it still doesn't work. For instance, if I select the Yast2 icon from the KDE menu, it prompts me to enter a password but nothing seems to work.

Any ideas? I tried some of the hacks to get it not even ask for my password (ie, using kwriteconfig) but those don't help either. It still asks for the root password and doesn't accept it even if I type it in correctly.
