Why are there 2 displayserver on entries?
I looked over the "displayserver on" entries. the second one does shut displayserver down.
Since the installer doesn't replace /sbin/init, displayserver isn't started at bootup, so you must start it manually from the menu.
If i choose voladj off, it just goes back to the voladj on choice, im not sure it makes the change
You should hear the difference when playing some songs...
