The first process listed in top is X. No surprise there. When that
happens to me I just quit X and restart it. No reboot required. Of
course, these days, almost everyone's Linux box starts up in X and stays
there until shutdown. So you're probably in xdm (or a custom flavor of
it for Gnome or KDE), and will have a harder time doing that.
