Comment 6 for bug 1801499

using Ubuntu 18.04LTS and caffeine/caffeine indicator will no longer prevent screensaver from activating - say - when playing full screen video - broken caffeine or broken Ubuntu (from latest update?)? Used to work fine - indicator will display on bar at top and allow 'activate' (steam comes out of 'cup'), but won't prevent Xscreensaver from running on full screen videos, etc. Any 'alternative'?
