The real question is: How to detect if a window has gone fullscreen (and out)?
I can turn off screensaver by doing xset s off, but will like to detect if a window has gone fullscreen. That way I can maintain the screensaver timeout for normal work and only turn it off when watching video.
This script from the i3ipc-python project will do this automatically for you.
Call this from your config with an exec_always directive. This may require the development version of i3 because of a bug where we don't get the fullscreen event when a fullscreen window closes.
Let me know if it works for you.
You can make a script and parse the output of i3-msg -t get_tree. There you should look for "fullscreen_mode".
As suggested, I wrote a script to parse the output of i3-msg -t get_tree and included it below for reference.
import json
import subprocess
i3_cmd = 'i3-msg -t get_tree'
def get_layout():
get_tree = subprocess.Popen(i3_cmd.split(), stdout=subprocess.PIPE)
stdout = get_tree.communicate()[0]
try:
tree = json.loads(stdout)
except ValueError:
tree = {}
return tree
def any_fullscreen_window(node):
if node['window']:
return node['fullscreen_mode'] == 1
return any(any_fullscreen_window(n) for n in node.get('nodes', ''))
def xset_screensaver(arg):
subprocess.call('xset s %s' % arg)
if __name__ == '__main__':
if any_fullscreen_window(get_layout()):
xset_screensaver('off')
else:
xset_screensaver('on')

Do you want this for any program in fullscreen mode or is your main concern in this watching movies without interruption? If its mainly movies, many movie players have options to turn of screen savers while playing. Which player are you using?
@Adaephon It is mainly videos, which can come in the form of different video players as well as browsers.
