今天重启两台Linux服务器登录到X时，报nautilus can't bu used now,due to an unexpected error错误，桌面区域内容无法显示，鼠标动作也失效，具体详细信息如下：
Nautilus can't be used now, due to an unexpected error from Bonobo when attempting to locate the factory. Killing bonobo-activation-server and restarting Nautilus may help fix the problem.
这是其实个bug，因为在登录到图形界面之前，bonobo-activation-server已经在运行，这是因为上次退出的时候bonobo-activation-server没有被正常的kill掉。
解决办法是：先kill掉 bonobo-activation-server，再重启nautilus,命令如下：
killall bonobo-activation-server
killall nautilus
nautilus & disown
