Bug Description

Binary package hint: gnome-power-manager

Despite the gconf items
/apps/gnome-power-manager/lock/use_screensaver_settings and
both being set to false, I am still prompted for a password when resuming my workstation from S3. I do not want to be prompted. Other than this, my suspend & resume work fine.

In the past couple days I've figured out a work around for this issue: I uninstalled gnome-screensaver and installed xscreensaver instead. This seems to have solved the issue. And I get better screens to boot!

Phillip Susi (psusi) wrote :

It looks like gnome-power-manager is not used to handle suspend any more. Indicator-session appears to directly lock the screen, kick off the screen saver, and ask UPower to transition the system to sleep mode. I can not see any dbus interface being exported by g-p-m to even ask it to suspend, so I guess that interface must have been removed. It does appear to still suspend when it decides the system has been idle long enough to auto suspend.

I think that the gpm interface needs put back and indicator-session needs fixed to call on it instead of handling the locking/screen saver and UPower calls itself. Either that or it needs to only call UPower, and if g-p-m wants to lock the screen then it should monitor for the Suspending signal UPower emits.

Adding an indicator-session task with it marked as "incomplete" to see if the other patches get merged as it effects how this should be accepted. I think this is the right approach, but there are a couple of dependencies here.

Adds signal arg

In Ubuntu, we got a bug filed about how suspends initiated outside of gnome-power-manager were not locking the screen correctly.

This is because it handled locking as a result of internal methods, not as a response to the Sleeping signal from upower. Ideally it would do that instead, but first, that signal needs to have enough information for a policy agent like gnome-power-manager to determine policy.

Which means it needs to tell listeners whether the sleep is a suspend or hibernate.

We received a patch for this by Phillip Susi (attached). It simply adds an int argument to the signal. Will existing dbus listeners be confused by the addition of a new argument?

Ah, sorry, searched bugs, but didn't think about the mailing list.

What about a second signal, named "SleepingFull" or something?

SleepingFull might be best, I though perhaps Sleeping2, but both seem non-ideal. Got any better ideas?


The only alternative to a second signal I can think of is a query method like GetCurrentSleepType(), but that's a whole 'nother round trip eating into the precious second before suspend (I don't know how much of a concern that is).

Oh, I think you meant naming ideas? SleepingWithType?

Eek. RTT is probably too high for that. Even setting a property might be racy, I'm not sure. A PropertyChanged signal in GDBus is run in a new thread, and I'm not sure how it works when we're using the clunky dbus-glib.

At the moment I'm erring for ::SleepingKind and ::ResumingKind as we call things kinds internally (rather than type, which upsets glib sometimes).

I filed upstream bugs with your patches, Phillip. I think upstream should probably greenlight such patches, as the new dbus signal argument will likely impact all listeners to that signal.

The Sleeping signal is deprecated, and removed in my branch. We won't get a new signal.
