X-Server access is denied on host
[Fatal Error] DISPLAY variable set incorrectly: :0
[Resolution] Verify that your DISPLAY environment variable is set correctly,
and that there is an X11 server on the system. If you are
running the Oracle Installer as a different user or on a different host,
you may need to use the xhost command to ensure that host/user
has permission to write to your display.
