Your Linux distribution may already contain the Remote Desktop Viewer program, which you can use to connect your Raspberry Pi with VNC. This program can usually be found under the Applications/internet menu (the following is an example of Ubuntu);
Once you select the Remote Desktop Viewer program and click the Connect button, you will see the following dialog box. Select VNC in the Protocol (Protocol) option, then enter the IP address of the Raspberry Pi and the screen number (ex: 0 or 1), complete example: 192.168.0.6:1.
Click the Connect button and you will see a prompt asking for a password. This is the password you specified before configuring the VNC service on the Raspberry Pi. You will see the remote desktop of the Raspberry Pi after you have entered it correctly.
If you want to exit on the Raspberry Pi desktop, do not use the logout (logout) menu. You just close the Remote Desktop Viewer window and then turn the VNC service off using the commands mentioned in the previous article on the Raspberry Pi.
Another alternative is the Remmia Remote Desktop Client, where you can download remmina.sourceforge.net.
