Banwagonhost: Ubuntu tutorial on building a visual interface VNC

If the Bricklayer VPS encounters any problem and cannot be connected, our first reaction may be to connect to the online VNC to see if there is any problem. However, there may not be a local VNC, and if it can only be used online, there will be many restrictions, such as being unable to copy and paste when typing. VNC (Virtual Network Console) is the abbreviation of virtual network console. It is an excellent remote control tool software developed by the famous AT&T's European Research Laboratory. VNC is an open source software based on UNIX and Linux operating systems. It has powerful remote control capabilities, is efficient and practical, and its performance is comparable to any remote control software in Windows and MAC. This tutorial guides you how to build the visual interface VNC in the cloud server of the Ubuntu operating system.

Ubuntu installation VNC software

First you need to log in to SSH and then update the system:

apt-get update

Execute the following command to install the software packages required for the desktop environment. Including system panel, window manager, file browser, terminal and other desktop applications.

apt install gnome-panel gnome-settings-daemon metacity nautilus gnome-terminal ubuntu-desktop

Install VNC.

Ubuntu 18.04:

apt-get install vnc4server

Ubuntu 20.04:

apt-get install tightvncserver

This completes the installation.

Configuring VNC Tutorial

Execute the following command to start VNC and set the password

vncserver

If the return result is similar to the following interface, the startup is successful:

Open VNC configuration file

vi ~/.vnc/xstartup

Press i to switch to edit mode and modify the content as follows:

#!/bin/sh export XKL_XMODMAP_DISABLE=1 export XDG_CURRENT_DESKTOP="GNOME-Flashback:GNOME" export XDG_MENU_PREFIX="gnome-flashback-" gnome-session --session=gnome-flashback-metacity --disable-acceleration-check &

Press Esc, type :wq, save the file and return.

Execute the following command to restart the desktop process.

vncserver -kill :1 #Kill the original desktop process and enter the command (where: 1 is the desktop number) vncserver -geometry 1920x1080 :1 #Generate a new session

Click here to go to the VNC Viewer official website, and download and install the corresponding version according to the operating system type of the local computer.

In the VNC Viewer software, enter the IP address of the cloud server: 1 and press Enter.

In the pop-up prompt box, click Continue.

Enter the set VNC password and click OK to log in to the instance and use the graphical interface.
