Wacomtblet is not using solid and it hasn't for a looong while, so this bug must be fixed.

Adding the two authors in CC, just to be sure.

So resolved fixed is not the propper status for this then.
But I will have a look into KScreen/Solid integration that we postponed since a while now

You are using an old version of the Wacom KCM. The method TabletDeamon::deviceAdded() was removed quite a while ago. Can you please check the latest version and report back if it works for you. You can find a link to the OpenSuSE RPMs on our project page.

Also, can you please disable the WacomTablet daemon in the KDE service manager and check if the crashes still occur. Just to make sure it is really us who are causing the crashes.

Hi Alexander,

I've got the latest version of _all_ RPM-packages of openSUSE 12.3 by an
update a few days ago (after problem reporting) and the segmentation
fault is still there.

I'm not quite sure how to do this. In _KDE3_ on another computer I could
find a Service Manager in the _Control Center_ under "KDE-Komponenten"
--> "Diensteverwaltung" (engl.: "KDE Components" --> "Service Manager"?
/1/), but in _KDE4_ _System Settings_ I can't find the corresponding
location.

But there is an Icon "Tablet" in the settings category below all others,
in German called "Nicht zuzuordnen" (engl.: "Not  assigned" or "Not
assignable"? /1/).
There I find the message:

"DBus connection to the kded deamon /2/ not available!"

and:

"Please start the wacom tablet deamon /2/ an try again.
The deamon /2/ is responsible for tablet detection and profile support."

There is obviously nothing to set in that category.

Right. I'll do this once I know where and will report the results again.

Just to not forget:

$ ps aux grep kded
USER       PID %CPU %MEM    VSZ   RSS TTY STAT START   TIME COMMAND
thomas    3355  0.1  0.8  92476  8348 ?   Sl   11:29   0:02 kdeinit4:
kded4 [kdeinit]


Bye for now!

Tom


/1/
I have set German as my language, so my re-translations into English may
not match the English originals but I hope you will recognize them however.

/2/
Wrong spelling! How to tell the translators?
Correct spelling: daemon or demon.

AFAIK OpenSuse does not ship the latest version of the wacom-table kcm. You can get the latest version for OpenSuse by following the link on our project page: https://projects.kde.org/projects/extragear/base/wacomtablet

On the other hand, if you do not have a Wacom tablet device, you might also consider uninstalling the wacom kcm or permanently disable it in your launch configuration (see below).

You can find the service manager by clicking on:

KDE Kontrollzentrum -> Starten und Beenden -> Diensteverwaltung -> KDE-Dienste beim Start

Make sure you disable the Wacom-Tablet service and apply the changes, so it will not be launched on startup.

Great, please let us know if your system still crashes even if the Wacom tablet service is disabled.

That's ok, you need the kded because it manages all KDE background services.

Ok, done for all users.

Ok, done for now with two users.

Now there's no crash message during kde startup :-)

I just wanted to say that the kded seems to run anyway after firstly
crashing on kde startup. But without service for wacom tablets this
misbehavior belongs to the past :-)


Thanks for the efficient dialog!


Bye, Tom
