You'll need to do 2 things to get what you want :

1) Create a simple bash script to start lampp

I've written it for you! It starts lampp if it isn't started and stops it if it's already started :

#!/bin/bash                                           ##This is a bash script



                                                      ##PREREQUISITES

if [[ ! -f /tmp/lampp-startstop ]] ; then             # if temp file doesn't exist

 echo 0 > /tmp/lampp-startstop 2>&1                   # create it and write 0 in it

fi



                                                      ##IF NOT RUNNING

if [ "`cat /tmp/lampp-startstop`" == "0" ] ; then     # if temp file contains 0

 sudo /opt/lampp/lampp start                          # start lampp

 echo 1 > /tmp/lampp-startstop 2>&1                   # write 1 in the temp file

 notify-send "Lampp" "Program started." -i xampp      # send a notification

 exit 0                                               # and exit

fi



                                                      ##IF RUNNING

if [ "`cat /tmp/lampp-startstop`" == "1" ] ; then     # if temp file contains 1

 sudo /opt/lampp/lampp stop                           # stop lampp

 echo 0 > /tmp/lampp-startstop 2>&1                   # write 0 in the temp file

 notify-send "Lampp" "Program stopped." -i xampp      # send a notification

 exit 0                                               # and exit

fi

2) Create a shortcut that will launch that script (on the Desktop for example) :

• A) Create a .desktop file on the Desktop :

  
  
  

  gedit ~/Desktop/Lampp.desktop 
  
  




• B) Enter the following in it :

  
  
  

  [Desktop Entry]
  
  Name=Lampp
  
  Comment=Start/Stop Lampp
  
  Exec=gksu bash /PATH/TO/THE/SCRIPT
  
  Icon=PATH/TO/THE/ICON
  
  Terminal=false
  
  Type=Application
  
  

  
  
  

  => Remplace the two /PATH/TO/THE/... by something. Icons are stored in /usr/share/icons/ and a good place for the script would be in your HOME folder, maybe hidden (hide by adding a . at the beginning of his name).




• C) Make it executable :

  
  
  

  sudo chmod +x ~/Desktop/Lampp.desktop
  
  

Note : the script isn't really checking if lampp is working, it is using a temporary file (disapears at reboot) containing 1 if you have used the script once (meaning it's started) and 0 if you haven't used the script (meaning it isn't started).
What does it mean ? That you have to only use this script if you want things to work : do not start lampp without this script and you'll be ok.

Note : you'll have to type your password in order to launch the shortcut. You could bypass that, but that wasn't your question so I will not explain that here.
