Uninstalling x.org and reinstalling sounds reasonable to me.  You might 
want to review rpm and yum  commands before deciding between the two. 
But, I *think* exiting the X window system and running  rpm -e <xorg 
base package> from a console followed by yum install <xorg base package> 
would do it.
