[CentOS] running X as root in centos 6

When I run X as root in centos 6
I get a nice little message that "your currently trying to run as root 
super user" and
are you sure you want to with a checkbox.

I do this for a reason as a post install step, then the system reboots 
and it never happens again...

I am trying to find how to set this checkbox which says "never ask me 
again" and move on...

I was trying to find it in gconf-editor but have not found it. Does 
anyone know where it is?

THanks,


Jerry
