關於startx的問題？ - Linux

Hi 各位：
是不是不能在pietty工具啟動startx呀，以下是出現的錯誤，
[test@localhost ~]$ startx
xauth: creating new authority file /home/test/.serverauth.4330


Fatal server error:
Server is already active for display 0
If this server is no longer running, remove /tmp/.X0-lock
and start again.

Xlib: connection to ":0.0" refused by server
Xlib: Invalid MIT-MAGIC-COOKIE-1 key
giving up.
xinit: unable to connect to X server
xinit: No such process (errno 3): Server error.
Couldnt get a file descriptor referring to the console

PS：我的os是CentOs 5.4版
