missing xconsole

I've lost the little xconsole of KDE startup for one user (me) but not for anyone else. Can anyone suggest where I look for reasons why it wouldn't appear? I've already looked in /etc/X11/xdm/Xsetup JDL -- Non enim propter gloriam, diuicias aut honores pugnamus set propter libertatem solummodo quam Nemo bonus nisi simul cum vita amittit.
