Description Michael Stather 2005-09-25 19:42:13 UTC 
When I launch KDE, the powersave applet always shows me the "plug" icon,
regardless whether my laptop is used on AC or not. It takes some time, about a
minute, until it displays the correct value. Is this is needed for fetching the
data from ACPI then its okay, but otherwise I suggest polling for the data if
the applet is started.
Comment 1 Holger Macht 2005-09-26 08:00:33 UTC 
First possibility:
hal-addon-acpi is not running or another process is accessing /proc/aci/event

So please post the two outputs of:
  ps aux | grep hal
  lsof | grep "\proc\/acpi\/event"


Second possibility:
As you already mentioned it could be the time for fetching acpi information.
Then you can try to boot with ec_burst=0 and check if the problem remains.
Comment 2 Michael Stather 2005-09-26 08:35:28 UTC 
I tried what you suggested:

hal-addon-acpu is running
the lsof grep doesn´t return anything (file isn´t in use)

and if I boot with the force parameter there´s no change.
I can live with this, if it takes so long to fetch the state from acpi. I just
thought that perhaps the applet (which seems to be maintaines by SuSE) doesn´t
fetch the data immediataly when it starts.
Comment 3 Holger Macht 2005-09-26 08:40:16 UTC 
Forgot to mention: You tried the lsof command as root?
Comment 4 Michael Stather 2005-09-26 08:50:40 UTC 
No unfortunately not *g
Now the result is:

acpid     5133       root    3r      REG        0,3       0 4026532095
/proc/acpi/event
Comment 5 Holger Macht 2005-09-26 09:08:34 UTC 
This looks ok.

Can you please do the following:

rcpowersaved stop
rchal stop
rchal start
rcpowersaved start

If you start kpowersave now, does the icon have the correct state immediately?
If so should be fixed in the final product.
Comment 6 Michael Stather 2005-09-26 10:08:41 UTC 
Yes now it displays the state immediately
Comment 7 Holger Macht 2005-09-26 10:24:35 UTC 
Ok, thanks. This will be fixed in final product. We changed the boot order to
let hal start after acpid.
