===== Install vncserver =====

vncserver will open a new X session to be accessed with a VNC client software only. After having made some tests I decided to replace it with x11vnc, which accesses the real X session currently running. Since the installation of vncserver took me some time, I will leave the hints in my Wiki.

==== Install server script ====

  apt-get install vncserver

==== Settings for vncserver ====

changes to vnc.conf. Notice that I mainly just uncommented a few things and wrote some lines following his examples of things that seem like they should be in there, such as the authority file, etc. The main change I made was doing:
$vncStartup = "$ENV{HOME}/.vnc/xstartup";
instead of:
$vncStartup = /etc/X11/Xsession";

  # User configuration
  # ------------------
  #
  # This section contains entries that may change from user to user.
  
  # $vncUserDir contains the filename for the log files directory of Xvnc
  #             (the server) and the viewers that are connected to it.
  # $vncUserDir = "$ENV{HOME}/.vnc";
  
  # $vncPasswdFile contains the filename of the password file for Xvnc.
  # $vncPasswdFile = $vncUserDir . "/passwd";
  
  # $vncStartup points to a script that will be started at the very beginning.
  # $vncStartup = "/etc/X11/Xsession";
  $vncStartup = "$ENV{HOME}/.vnc/xstartup";
  
  # $xauthorityFile should be the path to the authority file that should be used
  #                 by your vnc X server.
  $xauthorityFile = "$ENV{HOME}/.Xauthority";
  
  # $defaultDesktopName should be set to the default name of the desktop.
  #                     This can be changed at the command line with -name.
  # $defaultDesktopName = "X";
  
  # $geometry sets framebuffer width & height. Default will be calculated if
  #           server is started from within a running X servers. Can be changed at
  #           the commandline (-geometry). A fixed default will be used if
  #           vncserver is not invoked in a running X session.
  # Example:  $geometry ="640x480";
  $geometry = "1024x768";
  
  # $depth       sets the framebuffer color depth. Must be between 8 and 32.
  # $pixelformat sets the default pixelformat.
  #              The default will be calculated if none of both is specified
  #              and when vncserver is called from within a running X servers.
  #              Can be changed at the command line with option -depth.
  #              A fixed default value will be used if vncserver is not
  #              invoked in a running X session.
  # Example:  $depth = "16";
  #           $pixelformat = "rgb565";
  #depth = "16";
  $pixelformat = "rgb656";

xstartup file looks like this:
  #!/bin/sh
  unset SESSION_MANAGER
  exec /etc/X11/xinit/xinitrc

change execute permissions:
  chmod a+x /etc/X11/xinit/xinitrc
  cmmod a+x /home/bco/.vnc/xstartup

==== X display settings ====


After having started the vncserver for the first time, any X apps won't start anymore from KDE desktop or from the terminal windows. To resolve this, add username to the X server access list:
  xhost +local:username
This allows "username" to connect to the local running X server.
