Error: Can't open display: :0.0

Hi,

I get errors while running xclock from a non root user:

Code:
[root@localhost girish]# xclock        --- this works fine
[root@localhost girish]# su - girish
[girish@localhost ~]$ DISPLAY=:0.0; export DISPLAY
[girish@localhost ~]$ xclock
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

Error: Can't open display: :0.0
[girish@localhost ~]$

I basically want to install oracle. Please advice.

Regards,
Girish.
