Connect to Vivid Unit via VNC
Sometimes it will be more convient to control your Vivid Unit from another device (usually with bigger display, full sized keyboard and mouse etc.). If you just need a command line interface, you may connect to Vivid Unit via SSH. If you need desktop eniroment, then you can use VNC.
What is VNC?
VNC stands for virtual network computing, and it is a remote desktop sharing system for controling another computer remotely. VNC can display the remote computer’s desktop on your screen, and send your mouse and keyboard actions to the remote computer. This allows you to fully control the remote computer, just like using a local computer.
Enable/Disable VNC
By default Vivid Unit has x11vnc (VNC server) configured and enabled. You can run this command to check the VNC server status:
sudo systemctl status x11vnc
You will see something like this:
If you don’t want to expose this interface to others, you can disable VNC server by running this command:
sudo systemctl stop x11vnc
Check VNC server status again and you will see:
However this status only last until next reboot. If you want to indefinitely disable VNC, you can use this command:
sudo systemctl disable x11vnc
After running this command, VNC server will not start automatically after reboot.
