# chmod 775 .xsession
# echo xfce4-session > .xsession

# cat .xsession
xfce4-session

6，安装teamviewer实时控制桌面

# apt-cache search teamviewer
teamviewer - Remote control and meeting solution

# apt-get install -y teamviewer 

7，x11vnc 安装，实时远程桌面

• 安装 x11vnc

# apt-cache search x11vnc
# apt-get install -y x11vnc
# x11vnc -storepasswd

# cd /lib//systemd/system
# touch x11vnc.service
# chmod 775 x11vnc.service 
# vim /lib/systemd/system/x11vnc.service

[Unit]
Description=Start x11vnc at startup.
After=multi-user.target

[Service]
Type=simple
ExecStart=/usr/bin/x11vnc -auth guess -forever -loop -noxdamage -repeat -rfbauth /root/.vnc/passwd -rfbport 5901  -shared

[Install]
WantedBy=multi-user.target

• 运行 x11vnc

# systemctl daemon-reload
# systemctl start x11vnc.service
# systemctl status x11vnc.service

# systemctl enable x11vnc.service

• x11vnc 运行报错

# x11vnc
XOpenDisplay("") failed.

• 更新软件和系统

# apt-get update && apt-get upgrade && apt-get dist-upgrade

• 升级gnome

# apt-get install -y gnome-shell ubuntu-gnome-desktop
# gnome-shell --version
GNOME Shell 3.18.5

• 在本机运行x11vnc，使用其它主机ssh远程访问运行x11vnc会报错

XOpenDisplay("") failed.

• 使用vnc viewer 连接 X11vnc

# systemctl status x11vnc
● x11vnc.service - Start x11vnc at startup.
   Loaded: loaded (/lib/systemd/system/x11vnc.service; enabled; vendor preset: enabled)
   Active: active (running) since 日 2018-12-16 11:44:45 CST; 1min 28s ago
 Main PID: 5244 (x11vnc)
   CGroup: /system.slice/x11vnc.service
           ├─5244 /usr/bin/x11vnc -auth guess -forever -loop -noxdamage -repeat -rfbauth /root/.vnc/passwd -rfbport 5901 -shared
           └─5249 /usr/bin/x11vnc -auth guess -forever -loop -noxdamage -repeat -rfbauth /root/.vnc/passwd -rfbport 5901 -shared

• 使用 frp + x11vnc 替代 teamviewer

• frp 安装
  内网穿透 frp，ssh远程访问内网

• 修改frpc.ini 转发5901端口到VPS服务器

# vim frpc.ini 
[x11vnc]
type = tcp
local_ip = 127.0.0.1
local_port = 5901
remote_port = 5901

• 远程连接X11vnc ，服务器ip:5901
  

问题：有2个画面，分辨率不对
