Package: hal
Version: 0.5.10-2
Severity: normal
Due to the last upload of hal, there is regression in the support of pmu.
None of them seems complicated to fix as I was able to find workarounds
without prior knowledge of hal and dbus stuff..
The symptom was that I was no longer able to suspend to ram using kpowersave.
I used qdbusviewer to interacts with hald and also executed hals in a console.
I found that /usr/lib/hal/hal-system-power-pm-is-supported reports to hal that
my computer cannot suspend to ram. This is wrong. Since the regression, I was
able to suspend my computer using:
/usr/lib/hal/hal-system-power-pmu sleep
I believe that /usr/lib/hal/hal-system-power-pm-is-supported should be fixed to
at least say yes when an hal helper is able to do the job.
So I have added:
dbus-send --system --type=method_call --print-reply --dest=org.freedesktop.Hal \
/org/freedesktop/Hal/devices/computer
org.freedesktop.Hal.Device.SetPropertyBoolean \
string:'power_management.can_suspend' boolean:true
dbus-send --system --type=method_call --print-reply --dest=org.freedesktop.Hal \
/org/freedesktop/Hal/devices/computer
org.freedesktop.Hal.Device.SetPropertyBoolean \
string:'power_management.can_suspend_to_ram' boolean:true
to my /etc/rc.local to enforce hal to believe that my computer can suspend to
ram.
Now kpowersave offers the command. Yeah !!!
Second problem, /usr/lib/hal/scripts/linux/hal-system-power-suspend-linux is not
able to suspend to ram my computer. There the problem is that hal apparently
only
supports pm-utils. Again, adding those some lines solved the problem:
if [ $HAL_PROP_POWER_MANAGEMENT_TYPE == "pmu" ] ; then
if [ -x "/usr/lib/hal/hal-system-power-pmu" ] ; then
/usr/lib/hal/hal-system-power-pmu sleep
RET=$?
else
unsupported
fi
else
[...]
fi
My computer is an iBook G4 with those informations:
cat /proc/cpuinfo
processor : 0
cpu : 7447A, altivec supported

detected as : 287 (iBook G4)
pmac flags : 0000001b

So I submit this report to debian as I know that other debian users have the
problem. I do not really have time to forward it to hal bug tracking system,
even if I think that the regression is theirs. Do not hesitate to ask for more
informations.
So, I do not know what you can do, but it had to be reported.
Thanks for your work on hal.
Thanks in advance for your attention.
Best regards
