Xmanager登录RHEL弹出Close ESC解决办法

    机房新添置了几台Dell T7500微机工作站，装有RHEL5.5和R5000等软件。每当用Xmanager登录系统时就弹出Close ESC的对话框：

Close ESC:

ESC is already running, but is not responding. To open a new window, you must first close the existing ESC process, or restart your system.

    经百度得知，此现象与Smart Card有关，因我们不用esc，所以可通过yum remove esc来解决问题。如下所示：

[root@dell065 owr5000]# yum remove esc
Loaded plugins: rhnplugin, security
This system is not registered with RHN.
RHN support will be disabled.
