This is my current Vnc.conf \etc\ all i do now is type "vncserver" in the console.
Then XXX.XXX.XXX.XXX:1 in vnc viewer where x is the ip. or use hostname:1
You can have more than 1 "vitual" desktop by starting more than one vncserver change the :1 to :2 etc.

If you wnat to use this you may want to change the resolution to 800x600 if you have a lower res monitor.

$vncUserDir = "$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";

# $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";
$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 ="1152x864";
# $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 = "rgb565";
# $getDefaultFrom sets the display from which you can query the default of
# the above three options, if you don't want to start vncserver
# from within a running X server. It will be added to the call
# of xdpyinfo.
# It is useful to get the default from the X server you will
# run xvncviewer in.
# Example: $getDefaultFrom = "-display localhost:0"

# $rfbwait sets the maximum time in msec to wait for vnc client viewer.
# $rfbwait = "120000";
