Miriam,

Please avoid hijacking threads started by others.  You should start your own.  
I've changed the subject to describe your problem.

To start, please tell us your MacOS X version.

It appears to me that you've broken your X11 by installing XQuartz.  To verify 
...

(1) run /Applications/Utilities/Terminal
(2) At the command line type "xeyes"
(3) Tell us what happens
