Macworld | Mac OS X Hints | Disable the 10.5 X11 warning-on-quit dialog: "If you run GIMP or other X11 programs, they’ll launch X11 for you automatically in the background. When you quit those programs, however, they don’t automatically quit X11. When you do go to quit X11 yourself, you’ll be greeted (in OS X 10.5) with a confirmation dialog, asking if this is really what you want to do. After answering yes the first half-dozen times, this gets really old. Thankfully, there’s a simple Terminal solution. Quit X11, open Terminal (in Applications -> Utilities), and enter this command:

defaults write org.x.x11 no_quit_alert true
After that, X11 will no longer pester you when send it a Command-Q, or for you menu lovers, select File -> Quit X11. If you’d like the old behavior back, just repeat the above command (when X11 isn’t running), but replace true with false."
