1 本文适用范围

  • RK3399/RK3568/RK3588平台的ubuntu-focal-desktop系统
  • RK3588平台的debian-bullseye-desktop系统
  • RK3399平台的FriendlyDesktop请参考此文：How to setup VNC server on NanoPC-T4

2 Step1: 安装x11vnc

sudo apt update
sudo apt-get install x11vnc net-tools

3 Step2: 设置密码

su pi
x11vnc -storepasswd

4 Step3: 创建.Xauthority

touch /home/pi/.Xauthority
xauth add :0 . `mcookie`

5 Step4: 配置自动登录桌面

5.1 For ubuntu-focal-desktop

创建目录与文件 

sudo mkdir /etc/sddm.conf.d
sudo vim /etc/sddm.conf.d/autologin

autologin文件内容如下： 

[Autologin]
User=pi
Session=lxqt.desktop
Relogin=false

重启。

5.2 For debian-bullseye-desktop

默认情况下已经是自动登录，可通过如下文件检查配置 

$ grep autologin-user /etc/lightdm/lightdm.conf
# autologin-user = User to log in with by default (overrides autologin-guest)
# autologin-user-timeout = Number of seconds to wait before loading default user
autologin-user=pi
autologin-user-timeout=0

6 Step5: 开机运行x11vnc

新增文件 /etc/systemd/system/x11vnc.service 

sudo vim /etc/systemd/system/x11vnc.service

内容如下 

[Unit]
Description=Start x11vnc at startup.
After=network-online.target
 
[Service]
Type=simple
ExecStart=/usr/bin/x11vnc -display :0 -auth /home/pi/.Xauthority -rfbauth /home/pi/.vnc/passwd -rfbport 5900 -forever -loop -noxdamage -repeat -shared -capslock -nomodtweak
User=pi
Group=pi
WorkingDirectory=/home/pi
ExecStop=/bin/kill -TERM $MAINPID
ExecReload=/bin/kill -HUP $MAINPID
KillMode=control-group
Restart=on-failure
Environment=DISPLAY=:0
Environment=XAUTHORITY=/home/pi/.Xauthority
 
[Install]
WantedBy=graphical.target

启用systemd服务 

sudo systemctl daemon-reload
sudo systemctl restart x11vnc.service

7 Step6: 电脑访问

使用VNC客户端访问地址：
开发板IP:5900
