Description Bernd Steinhauser 2016-01-09 09:23:16 UTC

Since some time, I think since version 5.5, kscreen likes to spam the logs with the message:
kscreen: Failed to retrieve current config:  "Backend invalidated"

and sometimes
kscreen: Failed to retrieve current config:  "Failed to prepare backend"

This was mentioned in other bugs, but since I don't see their effects, I guess this is an independent issue.
There is no apparent effect noticeable, everything seems to continue working. Setting up the screen layout works fine.
Yet kscreen for some reason likes to push out this message every 10 s.

Reproducible: Always

Same here with version 5.5.5. My ~/.xsession-errors gets packed with those messages and grows large.
The strange thing is that those messages continue after uninstalling kscreen with
apt-get purge kscreen
and rebooting.
I also added the file ~/.config/QtProject/qtlogging.ini with the following content:
[Rules]
kscreen.debug=false

Lots of messages from kscreen disappeared but 
kscreen: Failed to retrieve current config:  "Backend invalidated"
kscreen: Failed to retrieve current config:  "Failed to prepare backend"
remain.

I don't find the messages anymore in the logs, so I guess it's been fixed at some point.
