I had a similar situation, but I had a monitor with built in speakers and it turned off automatically(screen saver/dpms), and I had to wake it up in order to play some songs and I could hear them :) The monitor was in sleep mode. I had a script that powered it back up: /***************************************************************/ #!/bin/sh export DISPLAY=3D:0 /usr/local/bin/xset dpms force on; /usr/local/bin/xterm -display :0 -bg white \ -e /usr/local/bin/mplayer --really-quiet -shuffle -playlist ~/.playlist -stop-xscreensaver & PID=3D$! > /dev/null 2>&1 sleep 1800 kill $PID /usr/local/bin/xset +dpms /***************************************************************/ The line that should do it is this one : /usr/local/bin/xset dpms force on; The rest was for playing music at a certain time :) [via crontab entry], several kind members of this list suggested the $PID=3D$! trick and then kill $PID. I was trying to use killall -9 /usr/local/bin/mplayer to stop mplayer from playing, then I found that pkill /usr/local/bin/mplayer to do it. But that was not optimal. Hope you test it and that it would work for what you intend to use it for :) Regards, Antonio
