第一步：安装VNCserver
- 指令：sudo apt-get install vnc4server
第二步：开启vnc服务
- 指令:vncserver
这里需要输入vnc链接的密码
看到..desk is master：1 说明已经启动了vnc服务。启动vnc成功后，会在主目录下产生一个.vnc目录（~/.vnc/）。 这时候window通过vnc链接到linux时，桌面系统是doc。
第三步：修改~/.vnc/xstartup文件
- #!/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 $HOME/.Xresources
- xsetroot -solid grey
- vncconfig -iconic &
- x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
- x-window-manager &
我们需要将最后一行“x-window-manager &”改为我们自己的Ubuntu图形界面服务，那么改成什么呢？这就要看你Ubuntu是什么桌面环境了，Ubuntu有gnome、KDE、Unity等桌面环境。
查看ubuntu桌面环境指令：vim/usr/share/gnome-session/sessions/ubutu.session
如果是gnome桌面，最后一行改成gnome-session &；如果是KDE桌面，最后一行改成startkde &；
如果是Unity桌面，桌面session的名称是ubuntu-2d，则将最后一行改为：
- export STARTUP="/usr/bin/gnome-session --session=ubuntu-2d"
- $STARTUP
第四步：如果原始linux系统没有配置桌面系统
(1)安装x－windows的基础
sudo apt-get install x-window-system-core（一般都已安装）
(2)安装登录管理器
sudo apt-get install gdm （还可以为kdm/xdm）
(3)安装Ubuntu的桌面
sudo apt-get install ubuntu-desktop
第五步：完美配置
- #!/bin/sh
- # DESK_TYPE=xfce
- DESK_TYPE=gnome
- # DESK_TYPE=unity
- # Uncomment the following two lines for normal desktop:
- unset SESSION_MANAGER
- unset DBUS_SESSION_BUS_ADDRESS
- # exec /etc/X11/xinit/xinitrc
- [ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
- [ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
- xsetroot -solid grey
- vncconfig -iconic &
- # x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
- # x-window-manager &
