a VNC (Virtual Network Computing) desktop. +-.B vncserver +-is a Perl script which simplifies the process of starting an Xvnc server. It +-runs Xvnc with appropriate options and starts a window manager on the VNC +-desktop. +- +-.B vncserver +-can be run with no options at all. In this case it will choose the first +-available display number (usually :1), start Xvnc with that display number, +-and start the default window manager in the Xvnc session. You can also +-specify the display number, in which case vncserver will attempt to start +-Xvnc with that display number and exit if the display number is not +-available. For example: +- +-.RS +-vncserver :13 +-.RE +- +-Editing the file $HOME/.vnc/xstartup allows you to change the applications run +-at startup (but note that this will not affect an existing VNC session.) +- +-.SH OPTIONS +-You can get a list of options by passing \fB\-h\fP as an option to vncserver. +-In addition to the options listed below, any unrecognised options will be +-passed to Xvnc - see the Xvnc man page, or "Xvnc \-help", for details. +- +-.TP +-.B \-name \fIdesktop-name\fP +-Each VNC desktop has a name which may be displayed by the viewer. The desktop +-name defaults to "\fIhost\fP:\fIdisplay#\fP (\fIusername\fP)", but you can +-change it with this option. The desktop name option is passed to the xstartup +-script via the $VNCDESKTOP environment variable, which allows you to run a +-different set of applications depending on the name of the desktop. +-. +-.TP +-.B \-geometry \fIwidth\fPx\fIheight\fP +-Specify the size of the VNC desktop to be created. Default is 1024x768. +-. +-.TP +-.B \-depth \fIdepth\fP +-Specify the pixel depth (in bits) of the VNC desktop to be created. Default is +-24. Other possible values are 8, 15 and 16 - anything else is likely to cause +-strange behaviour by applications. +-. +-.TP +-.B \-pixelformat \fIformat\fP +-Specify pixel format for Xvnc to use (BGRnnn or RGBnnn). The default for +-depth 8 is BGR233 (meaning the most significant two bits represent blue, the +-next three green, and the least significant three represent red), the default +-for depth 16 is RGB565, and the default for depth 24 is RGB888. +-. +-.TP +-.B \-cc 3 +-As an alternative to the default TrueColor visual, this allows you to run an +-Xvnc server with a PseudoColor visual (i.e. one which uses a color map or +-palette), which can be useful for running some old X applications which only +-work on such a display. Values other than 3 (PseudoColor) and 4 (TrueColor) +-for the \-cc option may result in strange behaviour, and PseudoColor desktops +-must have an 8-bit depth. +-. +-.TP +-.B \-kill :\fIdisplay#\fP +-This kills a VNC desktop previously started with vncserver. It does this by +-killing the Xvnc process, whose process ID is stored in the file +-"$HOME/.vnc/\fIhost\fP:\fIdisplay#\fP.pid". The +-.B \-kill +-option ignores anything preceding the first colon (":") in the display +-argument. Thus, you can invoke "vncserver \-kill $DISPLAY", for example at the +-end of your xstartup file after a particular application exits. +-. +-.TP +-.B \-fp \fIfont-path\fP +-If the vncserver script detects that the X Font Server (XFS) is running, it +-will attempt to start Xvnc and configure Xvnc to use XFS for font handling. +-Otherwise, if XFS is not running, the vncserver script will attempt to start +-Xvnc and allow Xvnc to use its own preferred method of font handling (which may +-be a hard-coded font path or, on more recent systems, a font catalog.) In +-any case, if Xvnc fails to start, the vncserver script will then attempt to +-determine an appropriate X font path for this system and start Xvnc using +-that font path. +- +-The +-.B \-fp +-argument allows you to override the above fallback logic and specify a font +-path for Xvnc to use. +-. +-.TP +-.B \-fg +-Runs Xvnc as a foreground process. This has two effects: (1) The VNC server +-can be aborted with CTRL-C, and (2) the VNC server will exit as soon as the +-user logs out of the window manager in the VNC session. This may be necessary +-when launching TigerVNC from within certain grid computing environments. +-. +-.TP +-.B \-autokill +-Automatically kill Xvnc whenever the xstartup script exits. In most cases, +-this has the effect of terminating Xvnc when the user logs out of the window +-manager. +-. +-.TP +-.B \-noxstartup +-Do not run the %HOME/.vnc/xstartup script after launching Xvnc. This +-option allows you to manually start a window manager in your TigerVNC session. +-. +-.TP +-.B \-xstartup \fIscript\fP +-Run a custom startup script, instead of %HOME/.vnc/xstartup, after launching +-Xvnc. This is useful to run full-screen applications. +-. +-.TP +-.B \-list +-Lists all VNC desktops started by vncserver. +- +-.SH FILES +-Several VNC-related files are found in the directory $HOME/.vnc: +-.TP +-$HOME/.vnc/xstartup +-A shell script specifying X applications to be run when a VNC desktop is +-started. If this file does not exist, then vncserver will create a default +-xstartup script which attempts to launch your chosen window manager. +-.TP +-/etc/tigervnc/vncserver-config-defaults +-The optional system-wide equivalent of $HOME/.vnc/config. If this file exists +-and defines options to be passed to Xvnc, they will be used as defaults for +-users. The user's $HOME/.vnc/config overrides settings configured in this file. +-The overall configuration file load order is: this file, $HOME/.vnc/config, +-and then /etc/tigervnc/vncserver-config-mandatory. None are required to exist. +-.TP +-/etc/tigervnc/vncserver-config-mandatory +-The optional system-wide equivalent of $HOME/.vnc/config. If this file exists +-and defines options to be passed to Xvnc, they will override any of the same +-options defined in a user's $HOME/.vnc/config. This file offers a mechanism +-to establish some basic form of system-wide policy. WARNING! There is +-nothing stopping users from constructing their own vncserver-like script +-that calls Xvnc directly to bypass any options defined in +-/etc/tigervnc/vncserver-config-mandatory. Likewise, any CLI arguments passed +-to vncserver will override ANY config file setting of the same name. The +-overall configuration file load order is: +-/etc/tigervnc/vncserver-config-defaults, $HOME/.vnc/config, and then this file. +-None are required to exist. +-.TP +-$HOME/.vnc/config +-An optional server config file wherein options to be passed to Xvnc are listed +-to avoid hard-coding them to the physical invocation. List options in this file +-one per line. For those requiring an argument, simply separate the option from +-the argument with an equal sign, for example: "geometry=2000x1200" or +-"securitytypes=vncauth,tlsvnc". Options without an argument are simply listed +-as a single word, for example: "localhost" or "alwaysshared". +-.TP +-$HOME/.vnc/passwd +-The VNC password file. +-.TP +-$HOME/.vnc/\fIhost\fP:\fIdisplay#\fP.log +-The log file for Xvnc and applications started in xstartup. +-.TP +-$HOME/.vnc/\fIhost\fP:\fIdisplay#\fP.pid +-Identifies the Xvnc process ID, used by the +-.B \-kill +-option. +- +-.SH SEE ALSO +-.BR vncviewer (1), +-.BR vncpasswd (1), +-.BR vncconfig (1), +-.BR Xvnc (1) +-.br +-https://www.tigervnc.org +- +-.SH AUTHOR +-Tristan Richardson, RealVNC Ltd., D. R. Commander and others. +- +-VNC was originally developed by the RealVNC team while at Olivetti +-Research Ltd / AT&T Laboratories Cambridge. TightVNC additions were +-implemented by Constantin Kaplinsky. Many other people have since +-participated in development, testing and support.
