I restarted E right now to give it a chance to reset its own
Screen Saver:
  prefer blanking:  yes    allow exposures:  yes
  timeout:  6    cycle:  0
DPMS (Energy Star):
  Standby: 16    Suspend: 17    Off: 18
  DPMS is Enabled
  Monitor is On

nothing happens after 6 seconds.

Can E reset it later, or I need to restart it like I did?
Shouldn't E reset it when I use the settings to change values and apply?

Mmmh, I have 3 chrome processes running.

Yes, I understand this. Bummer that so many apps can go and mess with
those settings without going through E
Once an app does this, is there a way to override it, or have X split a list of apps
that are blocking blanking?

so yes, I killed all my chromes, and now it works.
Restarted synergys, and it still works.

found this but the python code is too old, couldn't get it to work.

see https://github.com/jnerin/dbus-listen-inhibit/issues/2

also
https://bugs.chromium.org/p/chromium/issues/detail?id=931235

and
https://bugs.launchpad.net/ubuntu/+source/gnome-session/+bug/1600622
mentions trying this, but it doesn't work either
sauron:~$ dbus-send --print-reply --dest=org.gnome.SessionManager /org/gnome/SessionManager org.gnome.SessionManager.GetInhibitorsmethod 
Error org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.SessionManager was not provided by any .service fi

Now, as I write this, I restarted one chrome, display blank stopped working, killed it
and display blank is still not working even after restarting E :(

Is there anything E can do to help find the apps doing bad things, and override them
if possible?

Thanks,
Marc
