[CentOS] only root can use xwindows

After testing runlevel 5 i noticed that I cant switch to text consoles. 
So I went back to runlevel 3, but now normal users cant use graphic 
environment. I just got a black screen and an error message: Xlib: 
connection refused by server, Protocol unsupported by server
root can start xfce normally.
Any idea about whats happenning?
