Package: plasma-dataengines-workspace
Version: 4:4.8.4-2
Severity: normal
Dear Maintainers,
plasma engine powermanagement fails to convert upower output regarding
battery (dis)charging time estimation to internal data source. This
issue has been discussed upstream (see
https://bugs.kde.org/show_bug.cgi?id=290578 ) and is marked as done as
for KDE SC 4.8.0. It is still present in Debian's KDE SC 4.8.4,
therefore it is possible regression.
As upstream bug says, I have checked basic things:
1. if upower correctly reports battery state and (dis)charging
estimation:
#v+
$ upower --dump

#v-
The answer is: yes.
2. If KDE is able to convert this value and provide it in data engine:
#v+
$ qdbus org.kde.Solid.PowerManagement /org/kde/Solid/PowerManagement
org.kde.Solid.PowerManagement.batteryRemainingTime
0
#v-
The answer is: no.
3. In plasmaengineexplorer I have checked that source "Remaining msec"
is qulonglong. As comment #32 in upstream BTS says, the bug is caused by
type mismatch in
plasma/generic/dataengines/powermanagement/powermanagementengine.cpp .
Due to my lack of C++ skills, I can't tell if this is case here.
4. In kdebugdialog I have made sure that everything regarding Solid is
checked. Yet:
#v+
$ grep -i battery ~/.xsession-errors*
/home/minio/.xsession-errors:Object::disconnect: (sender name: 'Battery')
/home/minio/.xsession-errors:Object::disconnect: (sender name: 'Battery0')
#v-
Due to this bug, battery Plasmoid is unable to *read* how much time will
battery live before it runs out of power (it is unable to show it anyway
without manual editing of config files, but this is upstream design
decision; inability to convert is clearly a bug).
Best regards
