背景：
aarch64(arm64)系统，ubuntu 18.04，需在 Windows 远程连接系统桌面。

源

使用华为源：

sudo wget -O /etc/apt/sources.list https://repo.huaweicloud.com/repository/conf/Ubuntu-Ports-bionic.list
sudo apt-get update

安装命令

sudo apt-get install xrdp
sudo apt-get install vnc4server

安装桌面：

sudo apt-get install xubuntu-desktop

过程需选择默认桌面，选gdm3（另一为lightdm)。

注：最后提示：
