Better initialization command

export DISPLAY=\':0\' which translates to export DISPLAY=':0' 
has been changed to 
export DISPLAY=$(who -u | grep -o \"$USER\\s\\s:[0-9]\\+\" | grep -o \":[0-9]\\+\") which translates to export DISPLAY=$(who -u | grep -o \"$USER\\s\\s:[0-9]\\+\" | grep -o \":[0-9]\\+\")

The double greped who command is a dynamic replacement for the static default assignment of display :0. This dynamic command should always evaluate to whichever display USER is currently using X for. This is useful if other users are logged onto the same computer as the "switch user" method of logging on creates a new desktop eg: DESKTOP=:1. 

This has been tested on my computer for :0 and :1 and should work for most basic circumstances. However I do not know how it will respond if the user has created multiple desktop instances eg: via vnc4server.
