I'm trying to install Oracle 11g on RHEL5. But after I add user oracle, it cannot log in XWindow. I can log in as root. I tried "xhost +" or "xhost +si:localuser:oracle", but it seems like:

[root_at_ern pam.d]# xhost +

access control disabled, clients can connect from any host
[root_at_ern pam.d]# xhost

access control disabled, clients can connect from any host INET:ern
SI:localuser:root
[root_at_ern pam.d]# su - oracle
[oracle_at_ern ~]$ xclock

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

And after restarting the machine, it didn't work either. I stopped SELinux through GUI tools. Can anyone help me out? Thanks in advance.
