Hi
When the kdm is up and I can login to GNOME Okay, but I can't login to 
KDE the splash comes up and when it does it initializing it get to the 
keyboard and mouse it quits sends a Caught signal 4.  I did a apt-get 
update to see if the fixed the problem it did not.
What do I need to fix the problem
