I don't > see anything in Brave's settings. nope. it's a standard extension (xscreensaver extension). there is a call to suspend screensaver. rage uses this when in fullscreen mode to suspend blanking when you have an immersive living-room experience. browsers do this any time if media is playing now. it's a new-ish phenomenon, but it's a browser thing. you will have to bring this up with the browser authors and have them provide options. > > xset q will show > > the screensaver/dpms config and you'll probably find its what e set it to... > > Yes, i checked this before.

Now to figure out how to prevent it :) well .. close your browser. or close tabs. any tab with some kind of media playback will do it. i don't know if there is also some javascript that can do this too - i don't know. but in the end the problem is between you and your web browser to solve. :) perhaps the only option other than finding a browser setting (it may be in an advanced about:config setting)... is try make an LD_PRELOAD library that intercepts the xscreensaver (libXss) library calls and then makes the suspend blanking call be a NOP (do nothing). you set up this LD_PRELOAD for launching your browser thus denying it access to the feature it wants by force. you can then use this LD_PRELOAD for any misbehaving app... > Thanks, > -Conrad. > > -- > Shine like thunder > Cry like rain > -- ------------- Codito, ergo sum - "I code, therefore I am" -------------- Carsten Haitzler - ras...@rasterman.com _______________________________________________ enlightenment-users mailing list enlightenment-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/enlightenment-users
