closing laptop lid does not shut all applications down

  • 772

Well i was just thinking of having an app or a feature which enables you to play music even the laptop lid is shut close. what i want is that the screen should be locked ie no one should be able to do any other thing and at the same time my music should be contiued to play; virtually turning my lid-turned down laptop into a musical jukebox, ie a musical screen saver of sorts. Can anyone help me in achieving this? Any hints?

  1. You could try putting this in a file, marking it executable, and referencing it in your xinit or rc.local:

    #!/bin/sh
while true
do grep -v open /proc/acpi/button/lid/LID0/state
  if [ $? ]; then
    killall mplayer
  else
    pidof mplayer; if [ $? ]; then screen -d -m "sh -c 'mplayer -loop 0 -novideo /usr/share/example-content/Ubuntu_Free_Culture_Showcase/*' "; xlock; fi
  fi
  sleep 1
done

    It's pretty straightforward, ask me if you have questions. Obviously it will only work problem-free if you do not use mplayer while using it.
