This is a hard drive install of 9/5/03 3.2. I have apt-get upgraded everything. Everything works, then suddenly something breaks somehow:

I am using KDE and I have a couple users. Today I tried to login to one of the accounts, and the screen went blank and it clicked and then it came back to the KDM login screen.

I deleted that user and added it again. Tried logging in, but no luck...same thing.

I tried the other user, and couldn't login to that user either.

Root is the only user who can login to KDM.
