The result is such a problem.
Access to the system with Oracle username, the desktop is blank, can not do any operation.

The problem persists if the root user is restarted immediately. ALT+CTRL+F2 Switch to command window
Enter the root username password.

The problem still seems to be the problem of passwords.
