Every time the monitor is turned on after the screen timeout happens I get an authentication dialog. Reproducible: Always Steps to Reproduce: 1. let the display timeout and let kded4 powerdevil/solid power down the monitor. 2.After that, I press any key, and the dialog is there. Actual Results: Every time the monitor is turned on after the screen timeout happens I get an authentication dialog. Expected Results: as I have the policies Get brighness "org.kde.powerdevil.backlighthelper.brightness" and Set birghtness "org.kde.powerdevil.backlighthelper.setbrightness" set to YES, I expect no dialog at all. I get the following log: No outputs have backlight property kded(24813) PowerDevilUPowerBackend::brightness: org.kde.powerdevil.backlighthelper.brightness failed Object::connect: No such signal QDBusAbstractInterface::Changed() in kdelibs/solid/solid/backends/upower/upowerdevice.cpp:47
another easier way is just to kquitapp plasma-desktop. when restarted, the message is here again.
It is invalid. I had a PAM misconfiguration (trying to load a 32bit pam module)
It is still valid, after a total recompilation of KDE SC, and the fix for the PAM misconfiguration, it is here again.
Authentication you mean KAuth right? This is most probably happening because you are missing the file that authorize the "brightnesshelper" to be executed as root from your user. Check if this file exists: /etc/dbus-1/system.d/org.kde.powerdevil.backlighthelper.conf
Yes, KAuth. I have now the file you mention and the problem is gone. > cat /etc/dbus-1/system.d/org.kde.powerdevil.backlighthelper.conf <!DOCTYPE busconfig PUBLIC "-//freedesktop//DTD D-BUS Bus Configuration 1.0//EN" "http://www.freedesktop.org/standards/dbus/1.0/busconfig.dtd"> <busconfig> <!-- Only user root can own the foo helper --> <policy user="root"> <allow own="org.kde.powerdevil.backlighthelper"/> </policy> </busconfig>
