please respect org.gnome.desktop.screensaver idle-activation-enabled key

[Ryan Tandy]

GNOME Screensaver allowed me to disable screen blanking while still having the desktop marked idle if I don't touch it for some time. Unity allows the "idle-activation-enabled" key for schema compatibility but does not use it at all; the UI for disabling screen blanking implicitly disables marking the system idle altogether (this was true in GNOME too).

I don't have a patch ready right now but will work on one.

From the docs: «Set this to TRUE to activate the screensaver when the session is idle. DEPRECATED: This key is deprecated and ignored. Set org.gnome.desktop.session idle-delay to 0 if you do not want to activate the screensaver.»

Settings org.gnome.desktop.session idle-delay to 0 does the trick for you?

This key is deprecated and ignored. Set org.gnome.desktop.session idle-delay to 0 if you do not want to activate the screensaver.

[Ryan Tandy (rtandy)]

Setting idle-delay does disable the screensaver, but at the expense of having my session no longer marked idle at all. So for example, configuring logind to suspend or shutdown an idle computer is no longer effective. IMO this conflates two different things: whether or not the session is marked idle, and whether or not the screensaver is activated when that happens. But if that is indeed the intent of the design, feel free to reject this; and my apologies for wasting your time.

[Andrea Azzarone (azzar1)]

Mmm that's something that should be solved at a different level. We cannot support DEPRECATED gsettings keys, soon or later they are going to be removed, and if use an invalid gsettings key unity crashes. Please feel free to bug against gnome-session if you really need this feature.
