Description Martin Pitt 2009-06-05 03:54:47 UTC 
After switching g-p-m from using hal to using DK-P, g-p-m only displays 3 charge levels: 79%, 49%, or 19%. This is not actually g-p-m's fault, it gets the values from DK-P (see below for dump).

I'm not yet familiar with debugging DK-P, and battery issues in particular. What further information is helpful here?

Thanks in advance!

Martin

Comment 1 Martin Pitt 2009-06-05 03:57:39 UTC 
I asked the original reporter to test with 008 as well, will report back here. (Question about debugging procedures still stands, though).
Comment 2 Richard Hughes 2009-06-05 04:28:57 UTC 
You can follow whats happening with (as root):

killall devkit-power-daemon
/usr/libexec/devkit-power-daemon -v

And then watch the output scroll. You really want >=008 as earlier versions had pretty bad bugs.
Comment 3 Martin Pitt 2009-06-05 07:51:46 UTC 
Confirmed fixed in 008, sorry for the noise.
