The deal is that I just recently began to use Linux (Lubuntu) and I need some basic knowledge. My brightness on my Packard Bell Dot netbook is always on the highest, and the brightness control buttons aren't working. I found a command line to set the brightness level to a specific percentage. I‘d like to create three executables: 85%, 50%, 25%. My question is how do I make a file on my desktop which when clicked upon it runs a certain line of command. I don‘t want to open the terminal every single time.
