Centos 无法运行锁屏功能，如何解决？

Sanders.Chen

我这里正在运行Centos 4.5(Final)的版本，在用户使用锁屏(Protect your computer from unauthorizied use)就是Windows下的屏幕保护时，系统会提示无法使用.
详细如下：
cannot execute "xscreensaver-command -lock"
Details:failed to execute child process "xscreensaver-command" (No such file or directory)
请各位指点！

看来,又是没有希望啦.

1.显卡驱动有没有装？
2.是不是不小心删除了依赖包？
