Bug#524678: kde4-minimal: Battery Monitor widget doesn't support multiple batteries
I checked this the other day when KDE 4.4 came through in to unstable.
The same problem remains; there is multiple battery support for my X40
however I must have booted with both batteries installed.
IF I boot with just 1 and insert the 2nd after, it will not be
recognised by KDE.
IF I boot with both batteries and remove one, KDE will recognise this
appropriate as well as when it is re-inserted.
Given those two scenarios, I'm 99.9% sure this is a kernel issue and
not a KDE issue as the testing I've done shows that KDE behaves just
fine with two batteries, as long as it's aware of them.
