HOWTO: Disable screen saver while Flash is running

Run the following command in terminal:

mkdir -p ~/bin

Open gedit, or your preferred text editor and type this:

Skip code block

#!/bin/bash

# Cleanup any bad state we left behind if the user exited while flash was

# running

gconftool-2 -s /apps/gnome-screensaver/idle_activation_enabled --type bool true

we_turned_it_off=0

while true; do

sleep 60

flash_on=0

for pid in `pgrep firefox` ; do

if grep libflashplayer /proc/$pid/maps > /dev/null ; then

flash_on=1

fi

ss_on=`gconftool-2 -g /apps/gnome-screensaver/idle_activation_enabled`

if [ "$flash_on" = "1" ] && [ "$ss_on" = "true" ]; then

gconftool-2 -s /apps/gnome-screensaver/idle_activation_enabled \

--type bool false

we_turned_it_off=1

elif [ "$flash_on" = "0" ] && [ "$ss_on" = "false" ] \

&& [ "$we_turned_it_off" = "1" ]; then

gconftool-2 -s /apps/gnome-screensaver/idle_activation_enabled \

--type bool true

we_turned_it_off=0

fi

done

done

Save this file as "~/bin/flash_saver.sh"

Go back into terminal and run:

chmod +x ~/bin/flash_saver.sh

To run this, go into terminal and type:

~/bin/flash_saver.sh

If you prefer, you can set this script to run at logon by doing the following:

1. Run the program "Startup Applications"

2. Click "Add"

3. Under name type "FlashMonitor" or something you will recognise

4. Under command type "~/bin/flash_saver.sh"

5. Under comment (if you want) type a brief description. E.g. "Stops screen turning off when Flash is running"
