Hi Martin,

Okay, i see. Thanks for the hint!
I tried to find the relevant source code which is responsible for the screen locking, but I just skipped over the code. My bet would be screenShiels.js and some calls to a thing called loginManager? But what component exactly is initiating the dpms command? I didn't found it in the gnome-shell source code :-(
BTW do you know if xset will still work in Fedora 23 when gnome shell will switch to Wayland exclusively?
I'm not sure if a replacement exists for this command line tool! Or will xset continue to work?

Yes, I already found this setting beforehand.

Sadly I'm talking about a stream on mix cloud. Maybe it's somehow possible to extract the underlying audio track in the website... But I guess I would need an hour to do so, but in that time I would already have been listening the complete audio track, so...
With kind regards
