觉得通过windows原生的远程桌面访问服务器，也很有意思。我这里设置成功了，就分享给大家。
服务器使用的是lightdm显示管理器。大家可以尝试其它的显示管理器。
1. 安装xrdp，同时把建议安装的软件也装上

root@localhost:~# apt-get  install xrdp

2、配置xrdp
目的是让xrdp传输远程服务的2D桌面，默认传输的是3D桌面，可能会有问题。
root@localhost:~# vim /etc/xrdp/startwm.sh
#!/bin/sh

if [ -r /etc/default/locale ]; then
 . /etc/default/locale
 export LANG LANGUAGE
fi
echo "gnome-session --session=ubuntu-2d" > .xsession  # 新添加的行
. /etc/X11/Xsession

3、配置lightdm
这里需要配置XDMP服务器
root@localhost:~# vim /etc/lightdm/lightdm.conf
[SeatDefaults]
greeter-session=unity-greeter
user-session=ubuntu
greeter-show-manual-login=true
[XDMCPServer]
enabled=true

greeter-show-manual-login=true 指允许通过键入用户名和密码的方式来登录系统
XSMCPServer 字段指启动XDMCP服务器

4. 重启xrdp 和lightdm
root@localhost:~# /etc/init.d/xrdp rstart
root@localhost:~# /etc/init.d/lightdm rstart
5. 现在可以通过mstsc登录了便
