[Pkg-utopia-maintainers] Bug#638970: upower battery status flashing when both AC and battery are plugged in

Tue Aug 23 12:56:42 UTC 2011

Package: upower
Version: 0.9.12-1+b1
Severity: normal

When I plug in both AC and the battery, the KDE power management icon keeps
showing "no battery" for a fraction of a second, about twice a minute. Directly
after plugging AC in, there's even mire flashing. This did not happen before I
changed to Debian testing (I used Kubuntu before). I noticed that the backend
for power management was changed from HAL to upower, and indeed upower is the
problem here. Running "upower --monitor" for about a minute while not changing
anything power-related gives this output, in sync with the GUI:
