|
# 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, kscreensaver or gnome-screensaver 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/gnome-screensaver and PowerManagement.
