Debian, how to reconfigure X server?

["Al Puzzuoli" <apuzzuoli comcast net>]

Hello everyone.  After installing Debian Sarge, I am getting the "I can not 
start this X server" message upon bootup.  I assume that I  most likely 
answered something incorrectly during the initial X configuration, but don't 
know how to  run that configuration again.

Any help would be much appreciated.

Thanks,
