       vncviewer - VNC viewer for X

       /usr/bin/vncviewer [options] [host][:display#]
       vncviewer [options] -listen [port]

       vncviewer  is a viewer (client) for Virtual Network Computing.  This manual page documents
       version 4 for the X window system.

       If you run the viewer with no arguments it will prompt you for a VNC server to connect to.
       Alternatively, specify the VNC server as an argument, e.g.:

	      vncviewer snoopy:2

       where 'snoopy' is the name of the machine, and '2' is the display number of the VNC server
       on that machine.  Either the machine name or display number can be omitted.  So for  exam-
       ple  ":1"  means  display number 1 on the same machine, and "snoopy" means "snoopy:0" i.e.
       display 0 on machine "snoopy".

       If the VNC server is successfully contacted, you  will  be  prompted  for  a  password  to
       authenticate you.  If the password is correct, a window will appear showing the desktop of
       the VNC server.

       The viewer tests the speed of the connection to the server and chooses  the  encoding  and
       pixel format (colour level) appropriately.  This makes it much easier to use than previous
       versions where the user had to specify arcane command line arguments.

       The viewer normally starts out assuming the link is slow, using a  low  colour  level  and
       using  the  encoding  with  the	best  compression.  If it turns out that the link is fast
       enough it switches to full-colour mode and will use an encoding which compresses less  but
       is  faster  to  generate, thus improving the interactive feel.  Automatic selection can be
       turned off by setting the AutoSelect parameter to false, or from the options dialog.

       The viewer has a popup menu containing entries which perform various actions.  It is  usu-
       ally  brought  up  by  pressing F8, but this can be configured with the MenuKey parameter.
       Actions which the popup menu can perform include:

	 * switching in and out of full-screen mode

	 * quitting the viewer

	 * generating key events, e.g. sending ctrl-alt-del

	 * accessing the options dialog and various other dialogs

       By default, key presses in the popup menu get sent to  the  VNC	server	and  dismiss  the
       popup.  So to get an F8 through to the VNC server simply press it twice.

       A  full-screen mode is supported.  This is particularly useful when connecting to a remote
       screen which is the same size as your local one. If the remote screen is bigger,  you  can
       scroll by bumping the mouse against the edge of the screen.

       Unfortunately  this mode doesn't work completely with all window managers, since it breaks
       the X window management conventions.

       You can get a list of parameters by giving -h  as  a  command-line  option  to  vncviewer.
       Parameters  can	be  turned  on with -param or off with -param=0.  Parameters which take a
       value can be specified as -param value.	Other valid forms  are	param=value  -param=value
       --param=value.  Parameter names are case-insensitive.

       Many  of  the parameters can also be set graphically via the options dialog box.  This can
       be accessed from the popup menu or from the "Connection details" dialog box.

       -display Xdisplay
	      Specifies the X display on which the VNC viewer window should appear.

       -geometry geometry
	      Standard X position and sizing specification.

       -listen [port]
	      Causes vncviewer to listen on the given port (default 5500) for reverse connections
	      from  a  VNC  server.  WinVNC supports reverse connections initiated using the 'Add
	      New Client' menu option or  the  '-connect'  command-line  option.   Xvnc  supports
	      reverse connections with a helper program called vncconfig.

       -passwd password-file
	      If  you are on a filesystem which gives you access to the password file used by the
	      server, you can specify it here  to  avoid  typing  it  in.   It	will  usually  be

	      When you make a connection to a VNC server, all other existing connections are nor-
	      mally closed.  This option requests that they be left open, allowing you	to  share
	      the desktop with someone already using it.

	      Specifies that no keyboard or mouse events should be sent to the server.	Useful if
	      you want to view a desktop without interfering; often needs  to  be  combined  with

	      Start in full-screen mode.

	      Use automatic selection of encoding and pixel format (default is on).  Normally the
	      viewer tests the speed of the connection to the server and chooses the encoding and
	      pixel format appropriately.  Turn it off with -AutoSelect=0.

       -FullColour, -FullColor
	      Tells  the  VNC  server to send full-colour pixels in the best format for this dis-
	      play.  By default a low colour mode is used until AutoSelect decides  the  link  is
	      fast  enough.   However  if  the	server's  native pixel format is colourmapped (as
	      opposed to truecolour) then the server's format is used by default.

       -LowColourLevel level
	      Selects the reduced colour level to use on slow links.  level can range from  0  to
	      2, 0 meaning 8 colours, 1 meaning 64 colours (the default), 2 meaning 256 colours.

       -PreferredEncoding encoding
	      This  option  specifies the preferred encoding to use from one of "ZRLE", "hextile"
	      or "raw".

	      Render the mouse cursor locally if the server supports it (default  is  on).   This
	      can make the interactive performance feel much better over slow links.

       -WMDecorationWidth w, -WMDecorationHeight h
	      The total width and height taken up by window manager decorations.  This is used to
	      calculate the maximum size of the VNC viewer window.  Default is	width  6,  height

       -log logname:dest:level
	      Configures  the  debug  log  settings.  dest can currently be stderr or stdout, and
	      level is between 0 and 100, 100 meaning most verbose output.  logname is usually	*
	      meaning  all, but you can target a specific source file if you know the name of its
	      "LogWriter".  Default is *:stderr:30.

       -MenuKey keysym-name
	      This option specifies the key which brings up the popup menu.  The key is specified
	      as  an  X11  keysym name (these can be obtained by removing the XK_ prefix from the
	      entries in "/usr/include/X11/keysymdef.h").  Default is F8.

       Xvnc(1), vncpasswd(1), vncconfig(1), vncserver(1)
