NAME

       tigervncsession - start a VNC server

SYNOPSIS

       tigervncsession <username> <:display#>

DESCRIPTION

       tigervncsession is used to start a VNC (Virtual Network Computing) desktop.  tigervncsession performs all
       the necessary steps to create a new user session, run Xtigervnc with appropriate  options  and  starts  a
       window manager on the VNC desktop.

       tigervncsession is rarely called directly and is normally started by the system service manager.

FILES

       Several VNC-related files are found in the directory ~/.vnc:

       /etc/tigervnc/vncserver-config-defaults
              The  optional  system-wide  equivalent  of  ~/.vnc/tigervnc.conf.  If this file exists and defines
              options to be passed  to  Xtigervnc,  they  will  be  used  as  defaults  for  users.  The  user's
              ~/.vnc/tigervnc.conf  overrides  settings configured in this file.  The overall configuration file
              load order is: this file, ~/.vnc/tigervnc.conf, and then /etc/tigervnc/vncserver-config-mandatory.
              None are required to exist.

       /etc/tigervnc/vncserver-config-mandatory
              The  optional  system-wide  equivalent  of  ~/.vnc/tigervnc.conf.  If this file exists and defines
              options to be passed to Xtigervnc, they will override any of the same options defined in a  user's
              ~/.vnc/tigervnc.conf.  This  file  offers  a mechanism to establish some basic form of system-wide
              policy. WARNING! There is nothing stopping users from constructing their own  tigervncsession-like
              script  that  calls  Xtigervnc  directly to bypass any options defined in /etc/tigervnc/vncserver-
              config-mandatory. The overall configuration file load  order  is:  /etc/tigervnc/vncserver-config-
              defaults, ~/.vnc/tigervnc.conf, and then this file. None are required to exist.

       ~/.vnc/tigervnc.conf
              An optional server config file wherein options to be passed to Xtigervnc are listed to avoid hard-
              coding them to the physical invocation. This file uses perl(1) syntax. The special option  session
              can  be  used to control which session type will be started. This should match one of the files in
              /usr/share/xsessions. E.g., if there is a file called gnome.desktop, then $session="gnome";  would
              use that session type.

              To  be  compatible with the upstream provided wrapper scripts, we will fall back to trying to load
              configuration from ~/.vnc/config if tigervnc.conf is not present.  The  ~/.vnc/config  file  lists
              options  one  per  line.  Options  without  an  argument are listed as a single word, for example:
              "localhost" or "alwaysshared". For those requiring an  argument,  separate  the  option  from  the
              argument   with   an   equal   sign,   for   example,  "session=gnome",  "geometry=2000x1200",  or
              "securitytypes=VncAuth,TLSVnc".

       ~/.vnc/passwd
              The VNC password file.

       ~/.vnc/host:display#.log
              The log file for Xtigervnc and the session.
