Changing Behavior of Quit Button

[Rich Shepard]

   I'm running -4.6.1 on my laptop with Slackware-current. The behavior of
the "Quit" button up through the 4.6.1 version on Slackware-13.1 is to kill
the X server. What I see on the new installation is a icon box with choices
of logging off, shutting down, rebooting, etc. I don't want that. Sometimes
I want to kill the X server and continue working on a console.

   How do I re-configure the quit button to do this?

Thanks,

Rich
