Assuming you are using the KDE login screen (kdm) then:
	sudo /etc/init.d/kdm restart

This may not kill your current X session.

Control-Alt-Backspace in an X session will also force it to be
killed and then usually restarted by kdm (or similar). But it
usually disabled in "user-friendly" distributions like Ubuntu
because it is rather dangerous and some people hit it accidentally
(lord only know how).

In a console 'sudo kill /usr/bin/X' and 'sudo kill -9 /usr/bin/X'
will do the same.

But you said that had done a reboot, which will have done a restart
of X along with everything else.

It is possible that the communication between your X server and the
X clients (the programs) is broken somehow. Things to check are your
home directory, ~/.Xauthority (the X magic cookies file), and the
X socket files in /tmp/.X11-unix/.

The contents of /var/log/Xorg*log may also be useful.
