I have a Mandriva box that upgraded from 2008.1 to 2009, and is running KDE3. The same thing happened to me. I then found that /usr/sbin/userhelper had lost its suid root. I corrected that, and for the rest of that session I could give the root password. I didn't work on that box again for a few days, but on Friday I discovered that once more I can't give the root password. I haven't had time to investigate this further, yet. Maybe tomorrow. It does seem strange, though, that two distros are having the same problem, for no obvious reason. Anne
