kali linux安装中文输入法

Question

我操作如下：
修改sources.list

#官方源
deb http://http.kali.org/kali kali main non-free contrib
deb-src http://http.kali.org/kali kali main non-free contrib
deb http://security.kali.org/kali-security kali/updates main contrib non-free

#中科大kali源
deb http://mirrors.ustc.edu.cn/kali kali main non-free contrib
deb-src http://mirrors.ustc.edu.cn/kali kali main non-free contrib
deb http://mirrors.ustc.edu.cn/kali-security kali/updates main contrib non-free

#阿里云kali源
deb http://mirrors.aliyun.com/kali kali main non-free contrib
deb-src http://mirrors.aliyun.com/kali kali main non-free contrib
deb http://mirrors.aliyun.com/kali-security kali/updates main contrib non-free

apt-get install -f

apt-get update

apt-get install fcitx-googlepinyin

apt-get install fcitx-config-gtk2

reboot

到这里已经安装好了google输入法，但是输入法调不出来（看教程说ctrl+空格,但是就是调不出来）

（搞个输入法搞了两天，实在没办法了，只能上来提问了）
