after update KDE 3.2.1, can't log in as root

Hi, I did a update to KDE 3.2.1 with synaptic and after that i can't log in as root any more, with kde or windowmaker.... As a user no problems. Did have some error, when trying to log in with console in to something in the root, witch looks like " Xlib...." Have the error no more...sorry I have bin back to kde 2.3.0.. with no problems at all. Gerrit Jan
