What makes xset -dpms on my machine?

Question

I always xset +dpms. But nearly every day dpms is switched off again. How can I find out what program is doing this?

Most likely, the dpms setting is not recognised on restart due to a minhor incompatibility. Fallback to default is applied then. You can however easily work around by adding /bin/bash -c "sleep 15 && xset +dpms" to startup applications (Add to Startup Applications: Dash > Startup Applications > Add). If it solves your issue, I'll write it as an answer, please mention. — Jacob Vlijm, Oct 25 '16 at 09:20
Ok I watch if it is only reset after hybernation or if it is reset during the machine running. — , Oct 25 '16 at 16:52
It looks like the program "viber" is doing this when I make video chats. — , Oct 28 '16 at 13:27

Good catch! It might be worth to report this as a bug. (Desktop) applications shouldn't interfere with screen power states. That's a job for the display manager which can be instrumented via DBus on all Linux desktops. – David Foerster Nov 09 '16 at 18:49
Of course Viber is closed source and doesn't have a (public) issue tracker. The best I could find is their support ticket form. – David Foerster Nov 09 '16 at 18:53
I did use this ticket form but they do not understand what I want. This is only for customers which cannot open their microphone and similar things. – Nov 11 '16 at 23:03
I suspected as much. – David Foerster Nov 12 '16 at 07:55
