power management in recent kde/gnome (solved)

Hi all,

i was wondering : does power management work for anyone here in recent kde4 or gnome-2.3x versions ?
I mean, i tried kde4 and gnome-2.30.x in my powerbook and none of these knows f.ex. what a battery is.

As this happens in both kde and gnome i think that maybe i´m doing sth. wrong here.

TIA

I don't use KDE or Gnome, but I would be surprised if both KDE and Gnome were broken. Some possibilities:

Did you enable battery under ACPI in the kernel?
If you compiled it as a module, did you modprobe it before KDE/Gnome started?
Did you compile everything with the ACPI use flag set?

this is a powerbook, so no ACPI but PMU (and APM emulation).
It worked out of the box at some point not too long ago and i don´t think i have made any relevant changes.
The thing that bugs me is, like you say, that it doesnt work at all apparently, which makes me think that i´m doing sth. wrong.
Looking to what the apmd daemon does (or through the command line) it doesn´t look like any events are triggered _at all_ ... and i have no idea why nor where to start to debug ...

thanks anyways

Ah, my bad.

And the emulation is modprobed/built in? Hm. Have you rebuilt any of apmd's dependencies lately? If so, you might need a revdep-rebuild (or maybe just a recompile of apmd).

i always build all the power managment stuff into the kernel, so yes, apm emulation is in the kernel.
I *think* that maybe the issue comes from the apmd and powermgmt-base collissions, maybe the wrong file got installed.
There are several bugs open already about this issue ( like this one) without any apparent solution for apm users.

But in any case im not sure this is related or not and i have very limited access to this lappy ( its my wifes one actually) so that i don have much time to test and debug.

cheers

Hi Gringo, I'm not sure if I am getting the right meaning to your question, but just in the hopes that it might give you some info I can tell you that on gnome 2.26 (admittedly no recent) my wife's powerbook does see the battery and when it's charging and draining and such. I never got the ondemand governor to work (but this is something we discussed in another thread here).

yep, same thing here, but it does not work in anything higher than gnome-2.26. I don´t know about kde3, never tried that in this lappy, in kde4 i see the exact same behaviour.
One thing i mentioned that isnt true : if i launch the apmd daemon manually and watch for events, it catches only the first one but no other events are registered anymore ( apparently ...), so that this doesn´t look really like a problem of the DEs but like a more deeper problem somewhere.

i´m wondering why i´m the only one complaining about this though, if this is a general issue with gentoo there should be lots of threads about this problem.

thanks !

working now again in gnome-2.32, i suppose the switch to udev / upower did the trick.

cheers
