20.4 Starting the VNC Server

With the necessary packages installed and configured for the user’s account, the VNC server can be started as follows (making sure to run the command as the user and without superuser privileges):

$ vncserver

This will start the first desktop session running on the system. Since this is the first session, it will be configured to use port 5901 (which may be abbreviated to :1). Running the command a second time while the first session is running will create a VNC server listening on port 5902 (:2) and so on. The following command may be used to obtain a list of desktop sessions currently running:

$ vncserver -list

TigerVNC server sessions:

X DISPLAY # PROCESS ID

:1 1607

:2 4726

$ vncserver -kill :2

Alternatively, use the following command to kill all...
