hp 图形启动异常

用xmanager启动hp的时候提示下面错误，
     the desttop messaging system could not be started
   to correct the problem:
1  choose [ok] to return to the login screen.
2 select failsafe session from the login screen option menu and login in

3 check to see that desttop is properly installed the hostname is correct  (/etc/hosts ) and the network is probperly configufrd.

解决了 。是因为我改了ip地址后，忘记了改 /etc/hosts里面的。呵呵。
