unable to start X


I have installed linux Red Hat AS 3 and want to install Oracle Software from the DVD and when I login as root I can do the 'xclock' and see the clock but when I login as user 'oracle' I can not do the 'xclock'
Error Message
Xlib: connection to ":0.0" refused by server
Xlib : No protocol specified
Error : Can't open display :0.0

Do I have to export the display if yes then which IP:0.0 and how to get the ip address.

Please Help.

Thanks in Advance

That looks a lot like a similar problem in another instance of trying to get graphics applications to work when switching user from the login user. I refer specifically to this: a logged in user wants to su to root, then run an application that requires graphics. The same error messages are the result. The cure: the normal user issues the command 'xhost +localhost', then su to root, and start the app from the command line. The root user can then have a GUI app running.

So, my suggestion to you is to try that. Before logging in as oracle user, issue the command 'xhost +localhost', then login as oracle.

It's worth a try. If it fails, you haven't lost anything.
