devkit-power-daemon broken?

[Ankur Sinha]

hey,

I've had this issue for quite a while now.

I have a HP pavilion laptop that runs a Fedora 12 (up to date) and vista
(the original that came with the laptop). I'm using GNOME as of now.

When a power cut occurs, the power applet continues to show the adapter
plugged in,and battery at 100%. This restrains my system from
hibernating etc correctly, or even dimming display when ac power is
removed. 

I've already filed a bug here.

https://bugzilla.redhat.com/show_bug.cgi?id=554363

To confirm that there is indeed a bug, I've checked using acpi-tool,
htop all of which give correct values of battery and that there is no ac
power attached. 

As the bugreport says, killing /usr/libexec/devkit-power-daemon and re
running it corrects the status, however it's irritating to have to do
this every time a power cut occurs (if im around that is). 

Can someone think of a fix or at least a work around for the time
being?

I can confirm I see the same on a Dell Latitude D630C on F-12 as well.

There appear to be bugs on this issue[1][2] with lengthy discussions
already having taken place. The bug has been reported in 9/2009, which
is 6 months back. Can the concerned maintainers please prioritize this
bug and squash it asap? Proper functioning of power manager on a laptop
is really important. :)

AFAIK none of these are generic bugs. Handling AC plug/unplug is
actually not as simple as it seems, and can vary from device to device
(or, rather, ACPI implementation to ACPI implementation). So this is to
a degree system-specific.

It's totally system specific. I'm clearing bugs (and adding
workarounds) as fast as I can, but if you really want a bug fixed
"ASAP" you've essentially got two options:

* Pay someone for a support contract to diagnose and fix the bug (if
you pay Red Hat, I'll probably be me) -- this means it jumps my TODO
list by an order of magnitude.
* Find the bug and write a tiny patch to fix it, and send it to me

I've only got 24 hours in a day, just like everybody else.

That's really not what I meant. I really appreciate the work you're
putting into it. Thank you :)

I've got no idea of how this stuff works. If you could give some
references etc., I could at least begin to learn something on this and
*maybe* be able to write a patch someday (highly unlikely though :| )

Thanks

I know the first step is basically to kill the upowerd instance that's
running as a daemon and run it from a console instead, and examine what
happens when you do the plug/unplug.

Sometimes a BIOS firmware update solve these types of problems, a
update can be more ACPI-compatible. With the time, Linux kernel is
incorporating some BIOS tasks and fixing some bugs on some of these
BIOS.

Sometimes Linux or Fedora are innocents :)


Best regards.
