I'am using this script -- lightsOn, to delay screensaver when flash playing.

However, the script provides only the Chromuim way:

flash_process=`pgrep -lfc "chromium-browser --type=plugin --plugin-path=/usr/lib/adobe-flashplugin"`

I am using the official Google Chrome in xfce. Not familiar with shell programming, the screenshot of my process running in Chrome.

I want to know how to detect the process of flash player to make this script running? Thanks.

Have you tried changing it to flash_process=pgrep -lfc "google-chrome --type=plugin --plugin-path=/usr/lib/adobe-flashplugin"`` ? (although this might not work because chrome uses its own brand of flash) – Glutanimate Nov 17 '12 at 16:25
/opt/google/chrome/PepperFlash/ is what I see in Chrome 23 in chrome://plugins. – user25656 Nov 17 '12 at 18:28
@MHC Yeah, I have tried flash_process=pgrep -lfc "google-chrome --type=plugin --plugin-path=/usr/lib/adobe-flashplugin"``. It doesn't work still. – zfz Nov 18 '12 at 3:12

I have found a solution to disable xscreensaver when flash playing in Chrome.

Firstly, disable shockwave flash plugin at '/opt/google/chrome/PepperFlash/' in chrome://plugins as follows:

disable shockwave flash plugin

Then the command can detect flash process in chrome:

flash_process=`pgrep -lfc "chrome --type=plugin --plugin-path=/usr/lib/flashplugin-installer/"`

I have forked the script from github, and push the new one with Chrome flash detection. Here is the new script.

Well, the version of my google Chrome: chrome version

As Chrome uses the Pepper API, you can find the process referring to the chrome parameter 'type=ppapi'. You can do that using top/htop on the cmd line.

pgrep -lf "chrome --type=ppapi "
