Description Jeremy Huddleston 2009-04-12 10:11:00 UTC

Description of problem:
gnome-power-manager doesn't show any information about the battery.  /proc/apm shows the information.  I'm guessing that it's expecting acpi, but there's not acpi emulation for the powerbooks, just apm.

Comment 1 Richard Hughes 2009-06-03 08:13:06 UTC

What hardware is this? What does devkit-power --dump show?

Comment 2 Jeremy Huddleston 2009-06-03 20:00:15 UTC

This is a Powerbook G4

I have installed Ubuntu on it to avoid this and some other issues.

The problem is that the powerbooks emulate APM, but the widget only queries ACPI

It's not a widget, and it doesn't query the hardware itself, it either uses HAL or DeviceKit-power.

Okay, closing.

Comment 4 Jeremy Huddleston 2009-06-04 17:15:55 UTC

well that's what I mean.  HAL or DeviceKit-power does not have support for APM

And it's not likely to have either. There's a proper kernel class called power_supply that everything needs to be ported to. /proc/apm is going away RSN.

Comment 6 Jeremy Huddleston 2009-06-04 18:13:00 UTC

Right, I understand that.  That *IS* why this is a bug.  The compatibility layer for PowerBooks just provides APM emulation.  That needs to be fixed.

Ubuntu is reading the data from /proc/apm (or some other route) and getting it to gnome-power-manager, so I don't see a reason why Fedora can't as well.
