1. use putty to login Ubuntu, install vnvserver: sudo apt-get install vnc4server
2. edit $HOME/.vnc/xstartup as below
#!/bin/sh

# Uncomment the following two lines for normal desktop:
# unset SESSION_MANAGER
# exec /etc/X11/xinit/xinitrc

[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
#xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
#twm &
gnome-session &

3. start server: vncserver
4. in windows, use vncviewer to login 192.168.0.2:1

1. Make sure your root account is available in your Ubuntu. If not, try this command to reset its password to activate it:
sudo passwd root


2. Edit lightdm.conf file:
sudo gedit /etc/lightdm/lighdm.conf


3. Set the value of "autologin-user" to root:
autologin-user=root

        为了解决Windows远程桌面访问Ubuntu 12.04 , 采用XRDP，支持多用户登录并远程桌面。


1. install:

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


2. 安装完毕以后，执行以下命令:（该命令的作用是由于安装了 gnome桌面，ubuntu12.04中同时存在unity、GNOME多个桌面管理器，需要启动的时候指定一个，不然即使远程登录验证成功以后，也只是背景，其他什么也没有）
cd /home/youruser(youruser 是每个人自己的用户名)
echo "gnome-session --session=ubuntu-2d" > .xsession
sudo/etc/init.d/xrdp restart


3、运行Windows的mstsc





4. 远程成功.
