Ubuntu下skype不能输入中文的解决方法

之前用10.04英文版的Ubuntu，在软件中心安装skype后发现skype不能输入中文，其他地方都可以，后来不知怎的就好了，再后来重装系统11.10后又遇到这种情况，困扰很久没有解决，升级到12.04LTS还是老样子，上网苦苦搜索后终于得以解决。记方法如下：

确保系统已经安装ibus，如无，则安装$sudo apt-get install ibus ibus-qt4 ibus-gtk
按下面的文件来修改配置文件$sudo vim /etc/X11/xinit/xinput.d/default
重启系统则OK。
#
# This configuration provides default IM setting (user edittable)
# See im-switch(8) and /usr/share/doc/im-switch/README.Debian .

#
# Define IM for traditional X application with XIM

XIM_PROGRAM_XTRA=
# Set following variable to non-zero string if program set itself as deamon

#
# Define GTK and QT IM module
#   They may or may not be using xim as the IM.
#

QT_IM_MODULE=ibus

#
