To install it along with a few other packages which are required for the graphical interface to function properly, run the following command. During the installation, you might be asked whether you want to change a system file to a new version. Type y and then press enter to use the updated version. You will be prompted for a password. Set any password you like. You should now be able to connect using a VNC client. We need to configure VNC to launch the full Unity desktop when it starts.
To do it, first kill the VNC session. Common security options The most important thing when setting up a VNC server is to only let the right people access your desktop. The safest way to do that is usually to have someone sitting at the desktop deciding who gets to use it, but that's not always practical - for example, if you want to log in to your own computer from somewhere else. If you want to confirm each connection manually, you should look for these options: Request access each time - pop a window up asking whether to allow each connection as it comes in.
As well adding a little security, this avoids problems with both of you fighting over control of the mouse. Using these two options will give you the most security. Requesting access each time will ensure that nobody can connect without you noticing, and view-only access will mean that they can't change anything without asking you to do it for them.
If you want to access your desktop when nobody is sitting at it, these options will be more useful: Only allow local connections - only let people connect if they already have access to your computer. Set a password - require people to send a password before they can connect. These three options should give you a secure set-up, so long as they're used with port-forwarding.
Only allowing local connections means that only people with user accounts on your computer can access your desktop. Starting the server in "once" mode means that people with user accounts on your computer would have to log in to your desktop between the time you start your VNC server and the time you connect from your VNC client. Setting a password means that, if anyone did try to connect in that brief interval, they probably wouldn't be able to get in before you noticed and stopped the server.
There's no way to set vino to only listen for the next connection. To set a password, tick Require the user to enter this password: , and enter a hard-to-guess password. To put vino in view-only mode, untick Allow other users to control your desktop.
To only allow local connections, open a terminal and run the command: gsettings set org. Vino network-interface lo To allow connections from anywhere, open a terminal and run the command: gsettings reset org. Vino network-interface x11vnc x11vnc is a VNC server that is not dependent on any one particular graphical environment. It can be started while your computer is still showing a login screen. It is helpful to ensure you have uninstalled any other VNC programs first so that they don't interfere with x11vnc.
To set x11vnc to only listen for the next connection, include the -once option. To set x11vnc to continually listen for connections, include the -forever option. To put x11vnc in view-only mode, include the -viewonly option.
To set x11vnc to only allow local connections, include the -localhost option. Xauth -display :0 options to be specified on the command-line. The argument value for the -auth option may be found previously with x11vnc -findauth. Xauth -display :0 If you find a blank screen, check the x11vnc FAQ entry on headless servers. Because it's highly integrated with KDE, running it in other environments is difficult. To set krfb to request access each time, tick Confirm uninvited connections before accepting To set a password, type a hard-to-guess password into the Password input box.
To put krfb in view-only mode, untick Allow uninvited connections to control the desktop. There's no built-in way to only allow local connections, although see below for a solution. Once mode Krfb doesn't have a built-in way to accept the next connection then stop listening for connection attempts.

For example, " ssvnc far-away. For example " ssvnc far ", if you named the profile "far". You can use the -profiles option to list the profiles you have saved. See below and the application Help for more information on the modes. See its help output for more information. There are also some command line options described as follows. A profile is a destination host with specific parameter settings.
No SSL aspects are shown. Same as running the command sshvnc -ts Start in "Terminal Services Mode". Same as running the command tsvnc -tso Same as -ts "Terminal Services Mode", however never let the user leave this mode no button to switch modes is provided. This is the default. Same as -ss. You can toggle the mode with Ctrl-E. Note that when using the -via option, the host machine name should be specified as known to the gateway machine, e.
In TightVNC, this is the default mode, allowing you to share the desktop with other clients already using it. This would either disconnect other connected clients or refuse your connection, depending on the server configuration. Please be aware that operating in full-screen mode may confuse X window managers. Typically, such conflicts cause incorrect handling of input focus or make the viewer window disappear mysteriously.
This option disables such behaviour TightVNC-specific. Default is to use current Unix user name. If this option was given, the viewer will prefer Unix login authentication over the standard VNC authentication. This option affects only the standard VNC authentication. Encodings are specified separated with spaces, and must thus be enclosed in quotes if more than one is specified.
Available encodings, in default order for a remote connection, are "copyrect tight hextile zlib corre rre raw". For a local connection to the same machine , the default order to try is "raw copyrect tight hextile zlib corre rre".
Raw encoding is always assumed as a last option if no other encoding can be used for some reason. This reduces network traffic, but colors may be represented inaccurately. The bgr format is an 8-bit "true color" format, with 2 bits blue, 3 bits green, and 3 bits red. This allows the VNC server to control the colormap.
Level 1 uses minimum of CPU time and achieves weak compression ratios, while level 9 offers best compression but is slow in terms of CPU time consumption on the server side. Use high levels with very slow network connections, and low levels when working over high-speed LANs. It's not recommended to use compression level 0, reasonable choices start from the level 1.
Quality level 0 denotes bad image quality but very impressive compression ratios, while level 9 offers very good image quality at lower compression ratios. Note that the "tight" encoder uses JPEG to encode only those screen areas that look suitable for lossy compression, so quality level 0 does not always mean unacceptable image quality. Disabling JPEG compression is not a good idea in typical cases, as that makes the Tight encoder less efficient.
You might want to use this option if it's absolutely necessary to achieve perfect image quality see also the -quality option. Using cursor shape updates decreases delays with remote cursor movements, and can improve bandwidth usage dramatically. This option also disables the dot cursor, and disables cursor position updates in non-fullscreen mode. If the client represents itself as able to use multiple formats, the server will choose one.
Pixel format refers to the representation of an individual pixel. The most common formats are 24 and 16 bit "true-color" values, and 8-bit "color map" representations, where an arbitrary map converts the color number to RGB values. Encoding refers to how a rectangle of pixels are sent all pixel information in VNC is sent as rectangles. All rectangles come with a header giving the location and size of the rectangle and an encoding type used by the data which follows.
These types are listed below. All clients are required to support this encoding type. Raw is also the fastest when the server and viewer are on the same machine, as the connection speed is essentially infinite and raw encoding minimizes processing time. CopyRect The Copy Rectangle encoding is efficient when something is being moved; the only data sent is the location of a rectangle from which data should be copied to the current location.
Copyrect could also be used to efficiently transmit a repeated pattern.
