vmware虚拟机下使用ubuntu12.04，换成了gnome的界面，
安装了fcitx 4.25版本：
貌似使用gtk3，之前一直有个报错：

按照如下的方法重新设置了也不行：
1.去掉ibus，否则有冲突
$sudo apt-get purge ibus
2.设置环境变量，并默认启动
$vim .bashrc
export GTK_IM_MODULE=xim
export XMODIFIERS="@im=fcitx"
export QT_IM_MODULE=xim
fcitx& #当然，开机启动也可以在gnome-session-properties中添加
3.设置默认输入法
$gnome-language-selector 中选择fcitx
4.log out or reboot

============================
fcix官方说：说是因为安装gnome桌面，而gtk3的bug，导致dbus有问题，不仅仅是fctix，ibus也弹不出来，我试验了下，确实如此。
===================================
（1）今天重新卸载了fcitx，然后重新安装。
（2）新安装了fcitx-tools
新安装了fcitx-m17n
（3）发现fcitx的配置界面更新了：
（4）在语言中设置默认的输入法：
application --- system tools -----system settings---language support
选择fcitx。
（5）然后ctrl+space 切换输入法
工作正常了：
是fcitx更新了，还是我今天更新了系统的一些软件所致？
============
现在打开 终端输入看到的是：
