I was very surprised with my GLCD2USB plugged into my PC Engines Alix 
board. 1st the display was off. During boot as the USB driver loads the 
display came to life and the display screensaver [1] ran. When lcd4linux 
started, normal content was shown [2].

On shutdown the same in opposit happened. At the end, all was dark and off.

I would do it this way. However I wish to have a way to alter the 
brightness during run without changching the config file and restart 
lcd4linux.
