通過啟用屏幕共享來開啟遠程桌面登錄，開啟后需要關閉encryption，否則會出現無法連接的情況。關閉encryption可以使用系統配置工具dconf來完成。所以先安裝dconf-editor。
更新源並安裝系統配置工具(不更新源無法進行安裝)
1、查看系統版本
root@kali:~# lsb_release -a No LSB modules are available. Distributor ID: Kali Description: Kali GNU/Linux Rolling Release: kali-rolling Codename: kali-rolling
2、添加更新源，更新源內容可以從網上找到：
root@kali:~# root@kali:~# vim /etc/apt/sources.list # deb cdrom:[Debian GNU/Linux 2017.3 _Kali-rolling_ - Official Snapshot amd64 LIVE/INSTALL Binary 20171109-13:49]/ kali-rolling contrib main non-free #deb cdrom:[Debian GNU/Linux 2017.3 _Kali-rolling_ - Official Snapshot amd64 LIVE/INSTALL Binary 20171109-13:49]/ kali-rolling contrib main non-free #中科大 deb http://mirrors.ustc.edu.cn/kali kali-rolling main non-free contrib deb-src http://mirrors.ustc.edu.cn/kali kali-rolling main non-free contrib #浙大 deb http://mirrors.zju.edu.cn/kali kali-rolling main contrib non-free deb-src http://mirrors.zju.edu.cn/kali kali-rolling main contrib non-free #東軟大學 deb http://mirrors.neusoft.edu.cn/kali kali-rolling/main non-free contrib deb-src http://mirrors.neusoft.edu.cn/kali kali-rolling/main non-free contrib #重慶大學 deb http://http.kali.org/kali kali-rolling main non-free contrib deb-src http://http.kali.org/kali kali-rolling main non-free contrib #官方源 #deb http://http.kali.org/kali kali-rolling main non-free contrib #deb-src http://http.kali.org/kali kali-rolling main non-free contrib
3、更新：
apt-get clean && apt-get update
4、安裝dconf-editor
apt-get install dconf-editor
開啟遠程桌面共享
1、搜索共享，打開后進入屏幕共享配置界面，默認是已關閉狀態，設置狀態為活動並配置密碼：
2、搜索dconf打開系統配置編輯器，進入/org/gnome/desktop/remote-access/，編輯require-encryption配置項，把值設為false：
提交修改。
3、使用VNC Viewer遠程連接：
