Accessing Raspberry Pi using VNC Viewer
Although Raspberry Pi has the required packages installed to stream its graphical desktop, VNC Viewer is needed to access it. Since we are using an Ubuntu system to access Raspberry Pi, install VNC Viewer using the following command:
$ sudo apt-get install ssvnc
You may need to install xtightvncviewer using the following command:
$ sudo apt-get install xtightvncviewer
It is now possible to access the graphical desktop of Raspberry Pi using the following command:
$ xtightvncviewer 192.168.0.193:1
Replace 192.168.0.193 with the IP address of your Raspberry Pi. Enter the password to access it. Alternatively, the same results can be obtained using RealVNC Viewer package available on www.realvnc.com
Raspberry Pi can be logged on over SSH using an Ethernet network with Ubuntu system. Graphical desktop of Raspberry Pi running VNC server can be accessed using VNC Viewer. Internet can be accessed on Raspberry Pi by sharing the Wi-Fi connection of Ubuntu system. This configuration lets you access Raspberry Pi from any remote location using a laptop and a regular Ethernet cable.
Note that, vncserver does not start automatically when Raspberry Pi boots up. You need to start it using the command given below. Use SSH every time you want to access the graphical desktop of Raspberry Pi.
$ vncserver :1
