核心命令

[feng@fsc ~]$ ibus-daemon -r &

或

[feng@fsc ~]$ ibus-daemon -d -x -r

环境：fedora13 linux / kernel 2.6.31.5-127.fc12.i686.PAE / gnome

通知区域上ibus输入法的图标有时会显示不出来，有时启动后就没有这个图标的显示，注销并重新登录该图标一般就可以出现。

但是感觉如果为了一个ibus输入法框就注销重登录，实在有点小题大作了，只重启ibus应该就可以了，于是网上查重启ibus的方法。经查询大致有两种方法：

1. 杀死ibus进程，然后再次启动

killall ibus-daemon

ibus-daemon -d

2. 杀死ibus进程，然后再次启动

ibus-daemon -d -x -r

可以重新启动和启动ibus daemon图标

两种方法，比较起来，自然是第二种方法更好，直接粗野的杀死进程总是不安全的。

ibus进程是ibus-daemon，那就需要查看一个它的帮助说明文档，了解一下 -dxr参数都是什么作用，具体如下，整理整个过程的终端记录。

没有按照网上查得的重启命令，而是根据help文档，感觉使用ibus-daemon -r就可以，然而，问题出现了：当前进程还在前端运行，而非后台运行，结果是终端几乎死掉了，老半天都不反应，准备使用ctrl+z;bg 1把ibus进程放到后台也不可得。

只好ctrl+alt+F2,登录虚拟终端，ps aux|grep ibus

查出ibus的进程，kill 掉，回到之前的桌面环境里，运行

ibus-daemon -r &

搞定。

如下是终端记录：

[feng@fsc ~]$ ibus-daemon

current session already has an ibus-daemon.

[feng@fsc ~]$ ibus-daemon –help
