Thanks for the post. Unfortunately, this does not seem to be related to my issue. In any case, disabling sshd is not an option for me as I use this system sometimes as headless. As I said before, I can get the KDE login panel to appear by hitting CTRL-ALT-DEL and then ESC.  I have no X errors and only KDM errors which I quoted above from /var/log/messages.

Can anybody give me a clue as to where and/or what to look for to fix this?

Is there any other mail list or forum that would be able to get to the developers about this?

Thanks.
