Set up x11vnc on Ubuntu 22.04

 To set up x11vnc on Ubuntu 22.04, you can follow these steps:

1. Install x11vnc: Open a terminal window and run the following command to install x11vnc:

sql
sudo apt-get update
sudo apt-get install x11vnc sudo apt install lightdm

2. Generate a password file: Run the following command to generate a password file:

x11vnc -storepasswd

This will prompt you to enter a password and save it in a file named ".vnc/passwd" in your home directory. Ex: /home/thin/.vnc/passwd

3. Create a systemd service file: Create a new file named "x11vnc.service" in the "/etc/systemd/system/" directory with the following content:

makefile

[Unit]
Description=x11vnc service
After=display-manager.service network.target syslog.target

[Service]
Type=simple
ExecStart=/usr/bin/x11vnc -auth /home/thin/.Xauthority -forever -loop -noxdamage -repeat -rfbauth /home/thin/.vnc/passwd -rfbport 5900 -shared
ExecStop=/usr/bin/killall x11vnc
Restart=on-failure

[Install]
WantedBy=multi-user.target

This will create a systemd service file to start x11vnc at boot time and stop it when the system shuts down.

4. Reload the systemd daemon: Run the following command to reload the systemd daemon and load the new service file:

sudo systemctl daemon-reload

5. Enable and start the service: Run the following commands to enable and start the x11vnc service:

bash
sudo systemctl enable x11vnc.service
sudo systemctl start x11vnc.service

6. Verify that x11vnc is running: Run the following command to verify that x11vnc is running:

lua
sudo systemctl status x11vnc.service

This should show you the status of the x11vnc service and indicate that it is running.

7. Connect to x11vnc: Use a VNC viewer application to connect to your Ubuntu system using the IP address and password you specified earlier.
