vnc4server(1) - start or stop a VNC server
-name desktop-name
       Each desktop has a name which may be displayed  by  the  viewer.  It  defaults  to  "host:display#
       (username)"  but  you  can change it with this option.  It is passed in to the xstartup script via
       the $VNCDESKTOP environment variable,  allowing  you  to  run  a  different  set  of  applications
       according to the name of the desktop.
-geometry widthxheight
       Specify  the size of the desktop to be created. Default is 1024x768.  Can be specified as an array
       or scalar for geometry.
-depth depth
       Specify the pixel depth in bits of the desktop to be created. Default is 16, other possible values
       are 8, 15 and 24 - anything else is likely to cause strange behaviour by applications.
-pixelformat format
       Specify  pixel  format  for  server  to use (BGRnnn or RGBnnn).  The default for depth 8 is BGR233
       (meaning the most significant two bits represent  blue,  the  next  three  green,  and  the  least
       significant three represent red), the default for depth 16 is RGB565 and for depth 24 is RGB888.
-cc 3  As  an  alternative  to the default TrueColor visual, this allows you to run an Xvnc server with a
       PseudoColor visual (i.e. one which uses a colour map or palette), which can be useful for  running
       some  old X applications which only work on such a display.  Values other than 3 (PseudoColor) and
       4 (TrueColor) for the -cc option may result in strange behaviour, and PseudoColor desktops must be
       8 bits deep.
-kill :display#
       This  kills  a  VNC  desktop  previously started with vncserver.  It does this by killing the Xvnc
       process, whose process ID is stored  in  the  file  "$HOME/.vnc/".   It  actually
       ignores  anything preceding a ":" in its argument.  This can be useful so you can write "vncserver
       -kill $DISPLAY", for example at the end of your  xstartup  file  after  a  particular  application
