Using the default settings on a 4.6.3 install on Ubuntu 12.04, the desktop is not started properly when VNC Server in Virtual Mode  is launched.  A user connecting to VNC Server in Virtual Mode will see a backdrop and the VNC Server status window (without a title), but will not see any other desktop features such as toolbars or launcher.

The xstartup file should be created/modified as per below:

\--------------------------------------------------

\#!/bin/sh  
  
\# VNC Server (Virtual-Mode) start-up script compatible with Ubuntu 12.04  
  
\[ -r $HOME/.Xresources \] && xrdb $HOME/.Xresources  
xsetroot -solid grey  
  
vncconfig -iconic &  
  
if \[ -f /usr/bin/gnome-session \]; then  
  \# Some gnome session types won't work with Xvnc, try to pick a sensible  
  \# default.  
  for SESSION in "ubuntu-2d" "2d-gnome"; do  
    if \[ -f /usr/share/gnome-session/sessions/$SESSION.session \]; then  
      DESKTOP\_SESSION=$SESSION; export DESKTOP\_SESSION  
      GDMSESSION=$SESSION; export GDMSESSION  
      STARTUP="/usr/bin/gnome-session --session=$SESSION"; export STARTUP  
    fi  
  done  
fi  
  
if   \[ -x /etc/X11/Xsession \]; then /etc/X11/Xsession  
elif \[ -x /etc/X11/xdm/Xsession \]; then /etc/X11/xdm/Xsession  
elif \[ -x /etc/X11/xinit/Xsession \]; then /etc/X11/xinit/Xsession  
elif \[ -x /etc/gdm/Xsession \]; then /etc/gdm/Xsession gnome-session  
elif \[ -x /etc/kde/kdm/Xsession \]; then /etc/kde/kdm/Xsession  
elif \[ -x /usr/dt/bin/Xsession \]; then  
  XSTATION=1 DTXSERVERLOCATION=local /usr/dt/bin/Xsession  
elif \[ -x /usr/dt/bin/dtsession \]; then /usr/dt/bin/dtsession  
else  
  if which twm > /dev/null 2>&1; then  
    xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &  
    twm  
  else  
    xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop"  
  fi  
fi  
  
vncserver -kill $DISPLAY

\--------------------------------------------------

Creating this file in ~/.vnc/xstartup and making the file executable should resolve the issue by launching a Unity session for VNC Server in Virtual Mode.  Alternatively, it can be copied to /etc/vnc/xstartup.custom and made executable to make it a system-wide default.
