装完scrot就这样：
[root@minilab laborc]# scrot
No protocol specified
No protocol specified
giblib error: Can't open X display. It *is* running, yeah?
[root@minilab laborc]#

还有按那个PrintScreen键,就出来一个错误的窗口：
Metacity:
There was an error running gnome-screenshot:

Failed to execute child process "gnome-screenshot" (No such file or directory)

还有：
[root@minilab laborc]# emacs &
[1] 1740
[root@minilab laborc]# No protocol specified
No protocol specified
Display :0.0 unavailable, simulating -nw

这个是因为你没有安装gnome-utils吧。
其他的是因为已经有个X进程再运行了。

$ xhost +    //就解决了

The xhost program is used to add and delete host names or user names to the list allowed to make connections to the X server. In the case of hosts, this provides a rudimentary form of privacy control and security. It is only sufficient for a workstation (single user) environment, although it does limit the worst abuses. Environments which require more sophisticated measures should implement the user-based mechanism or use the hooks in the protocol for passing other authentication data to the server.
