Description Michal Bryxí 2010-01-13 19:09:21 UTC
Version:            (using KDE 4.3.4)
Installed from:    Gentoo Packages

Every time I'm in a hurry. I just press suspend button on my laptop, put it (laptop) in a bag a run wherever I need to be. 
And in some of these situations Amarok was playing before the suspend. So I'm a little nervous everytime when I have to wake up my laptop on a meeting. Did I paused Amarok? 

It would be really nice if Amarok can (optionally) pause itself on suspend.

Sounds reasonable :)
Comment 2 Kevin Funk 2010-07-08 16:55:55 UTC
Technically not possible at all. Spoke to some Solid people. Sorry :(
Comment 3 Michal Bryxí 2010-07-08 19:23:55 UTC
Huh? Ok, you're the expert, but why? When I press the power button on laptop notification pops up and says "hey your laptop is going to sleep". Theoretically I can create a script which runs alongside with this notification and pauses amarok. But I'd rather have it as out-of-box feature in amarok.
Comment 4 Kevin Funk 2010-07-08 19:29:04 UTC
Afaik powerdevil is handling this. It doesnt provide a infrastructure to notify listeners on this event. It just throws a KNotification and then suspends immediately (I already looked at their code).
There's no time to react on this.

Ask upstream (powerdevil maintainer) to provide some signalling before actually going down.
Comment 5 Michal Bryxí 2010-11-17 23:52:21 UTC
As #244124 was implemented I pledge once again for this feature to be implemented.
Comment 6 Myriam Schweingruber 2010-11-20 16:57:49 UTC
Bug 244124 being solved, I'm reopening this wish.
Comment 7 Kevin Funk 2010-11-25 19:55:54 UTC
Please note that this could take some time. We still depend on KDE 4.4.
Comment 8 Mayank Madan 2012-11-29 18:08:39 UTC
Reproducible in 2.6-git
Comment 9 Janos Zsitvai 2013-01-04 14:42:09 UTC
Sorry about the noise, I only attempted to add myself to the CC list and instead seem to have removed most people. :(
Comment 10 Janos Zsitvai 2013-01-04 14:49:05 UTC
..except that was bug #296100 and I haven't actually removed anyone, it just jumped to this bug next? 

Sorry again, this bug tracker is confusing me.
Comment 11 Christoph Feck 2013-01-05 20:46:04 UTC
On the bugzilla "Preferences" page, you can change that behavior.
Comment 12 Janos Zsitvai 2013-01-05 22:04:22 UTC
Thanks! The default behavior took me by surprise.
Comment 13 Anmol Ahuja 2013-04-01 17:38:08 UTC
I wanna work on this bug. But it seems to conflict with https://bugs.kde.org/show_bug.cgi?id=301512 . How should I go about this?

Comment 15 Matěj Laitl 2013-04-03 23:03:45 UTC
Anmol, thinking more about this bug and bug 259862, I think we should have 3 mutually exclusive radio buttons in Amarok Playback config:

When Amarok is playing:
 (a) Prevent system from going to sleep
 (b) Allow system to go to sleep, but pause playing
 (c) Allow system to go to sleep, resume playing on resume

[question is what should be default and if other devs are happy with this - I'm going to bring this to amarok-devel@kde.org - please watch it]

Anmol, please update the patch accordingly and attach a screenshot of the changed dialog to the review request.

P.S: Kudos to you Anmol for recent inflow of patches - you independently pick and fix bugs, something that counts should you apply for GSoC.
Comment 16 Anmol Ahuja 2013-04-04 03:52:26 UTC
I found out(on #solid) that Solid::PowerManagement::beginSuppressingSleep() can only inhibit automatic system sleep. So the two options aren't really mutually exclusive and there is another possible combination:
Prevent system from going to [automatic] sleep, and pause playback on [manual] sleep.
Should I add 4 radio buttons then?

And thanks :)
I would like to apply for GSoC, actually.

I'll get working on them by tonight (GMT+5.5).
