[Bug 218187] New: digikam activates screensaver which is not set

[Hartmut]

https://bugs.kde.org/show_bug.cgi?id=218187

           Summary: digikam activates screensaver which is not set
           Product: digikam
           Version: 0.10.0
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: general
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:           0.10.0 (using 4.3.4 (KDE 4.3.4) "release 2",
KDE:KDE4:STABLE:Desktop / openSUSE_11.1)
Compiler:          gcc
OS:                Linux (x86_64) release 2.6.27.37-0.1-default

My screensaver is deactivated. When I start a picture-show with
Digikam/Showfoto/Gwenview the screensaver is set, when the picture-show ends.
Worst: the checkbox in systemsettings is not checked. I wish that Digikam
checks, if the screensaver is set and deactivates it only when the saver is
set.

This is irrelevant of digiKam. we never touch KDE screensaver settings...

It is fact: I have no screensaver, my computer can run days without
screensaver appearing. But if I run a pictureshow one minute after the
end of the show my sceen is black, but not black because of
monotor-sleeping - black with backlight. And we have three maschines
here - all do the same.

perhaps this is the kipi-plugins Slideshow (and not digikam)?

Maybe, but how do I know? It's not a crash, where I can see which modul
has crashed  ...

Complement: it is the screensaver and nothing else, because if I if I go
to systemsettings/screensaver and "activate" it (it is activ but not
checked) and then deactivate it, the screensaver is off.

The answer to Rex' question is which slideshow you select:
From the "Slideshow" button you can choose between four different actions -
All, Selection, Including subalbums, or Advanced Slideshow.

It happens with All, Selection, Including subalbums. The advanced
slideshow crashes my x-server!

Digikam uses the standard freedesktop screensaver inhibition interface via
DBus. In fact, the relevant code is copied verbatim from okular. (that means,
starting a presentation from a PDF in okular should give the same problem).

I tried it and you are right: its the same with okular. I did not find
out earlier, because I never ever startet a presentation of PDFs ...
What do I do now? Bugreport or wish to bugs@okular?

Either the code in okular and digikam is wrong, though I dont see what could be
wrong there.
Or there is a problem with the process implementing the DBus interface. For a
normal KDE/Plasma desktop, that is KRunner.

Here i've got the exact same problem.

I think its caused from a wrong KRunner implementation of the screensaver.
Specificly screensaver/saverengine.cpp from krunner
(
http://websvn.kde.org/trunk/KDE/kdebase/workspace/krunner/screensaver/saverengine.cpp
).

The code for uninhibiting doesn't check whether the screensaver is enabled
altogether (line 424).
As long as an application inhibits and later uninhibits the (possibly disabled)
screensaver, the screensaver gets enabled. The correct call in this line should
read

enable( KScreenSaverSettings::screenSaverEnabled() )

Maybe somebody can reassign this bug to krunner ?
