I have no answer to this problem (it has happened to me several time),
but I can provide some additional information. Hopefully someone will be
able to suggest where to look the next time this occurs.  I am running
SuSE 7.2 with a 2.4.4 kernel and KDE 2.2.1.  Note that as I rember I
also saw this happen a couple of times with a 2.2.x kernel and an
earlier version of KDE. 

* When this event occurs the local keyboard and mouse is locked.
Therefore       X can not be terminated by cont+alt+backspace nor can a
switch to              another terminal.

* I can login via ssh from another syster and execute commands.
Before           anyone asks, I have killed all processes, I think,
associated with KDE         and X. However, the keyboard, mouse and
screen on the effected system          remain locked.  After su to root
I have tried halting the system, but          only a partial halt is
made.  By this I mean a system going down               message is
received at the log in terminal and network connection is           lost
and the locked system never reaches run level 0.  After a          
manual reset of the system fschk is run on all partitions during
reboot        so that it appears the shutdown process occurs prion to
unmounting.

I have not been able to find anything in the logs indicating any problem
detected by KDE, X or the kernel. My guess at this time is some locking
process has occured, but I have no idea where to start looking..Therfore
it is not clear where this problem lies .ie kernel, X or KDE.

Hopefully someone will have some suggestions of where to look, what
debug funtions to use, or ? that I can do the next time this occurs so
that a meaningful bug report can be made to the developers.  Since this
happens  rarely, it may be awhile before I can provide any further
information other than what I have forgotten to mention.
