+# This script is licensed under GNU GPL version 2.0 or above
+
+# Description: Bash script that prevents the screensaver and display power
+# management (DPMS) to be activated when you are watching Flash Videos
+# fullscreen on Firefox and Chromium.
+# Can detect mplayer and VLC when they are fullscreen too but I have disabled
+# this by default.
+# lightsOn.sh needs xscreensaver or kscreensaver to work.
+
+# HOW TO USE: Start the script with the number of seconds you want the checks
+# for fullscreen to be done. Example:
+# "./lightsOn.sh 120 &" will Check every 120 seconds if Mplayer,
+# VLC, Firefox or Chromium are fullscreen and delay screensaver and Power Management if so.
+# You want the number of seconds to be ~10 seconds less than the time it takes
+# your screensaver or Power Management to activate.
+# If you don't pass an argument, the checks are done every 50 seconds.
+
+
+# Modify these variables if you want this script to detect if Mplayer,
+# VLC or Firefox Flash Video are Fullscreen and disable
+# xscreensaver/kscreensaver and PowerManagement.
