Set the password for the user or users defined in the configuration file. Note that you need to switch from root to USER first. The stored password is not encrypted; anyone who has access to the password file can find the plain-text password. If you want to configure more than one user on the same machine, create different template-type service files, one for each user. In both these files substitute USER with the correct user name.
To start or enable the service, specify the display number directly in the command. With a valid display number, execute the following command:. You can also enable the service to start automatically at system start. Then, when you log in, vncserver is automatically started. As root , issue a command as follows:. At this point, other users are able to use a VNC viewer program to connect to the VNC server using the display number and password defined.

Or, when your system is running, you can stop the service by issuing the following command as root :.
For operating the vncviewer , there is a pop-up menu containing entries which perform various actions such as switching in and out of full-screen mode or quitting the viewer. Alternatively, you can operate vncviewer through the terminal. Enter vncviewer -h on the command line to list vncviewer 's parameters. In order to do so, issue the vncviewer command in the following format:. With the IP address When using a non-encrypted connection, firewalld might block the connection.

Note that for display numbers greater than 3 , the corresponding ports will have to be opened specifically as explained in Opening Ports in firewalld. But now all I get is a blank screen after entering the password. Thanks for updating us about these changes, let me give a try to this TightVNC on my Fedora 28, will get back to you with solution.
