Hello list,
do you think it would make sense to generate an /proc/acpi/event, whenever the
power-supply gets connected or disconnected?
Bye
Karl

There is one. Well, two actually. One for connecting and one for
disconnecting. ;-)

Sorry to have bothered you with my less-than-new ideas ;-)
Of course I tried to disconnect and reconnect the power supply, and I saw the
state was getting set to online and offline, but doing the same with a cat
listening on /proc/acpi/events did not see any events from un-/re-plugging. I
am rebooting my laptop to verify this behaviour. And yes: In
/proc/acpi/ac_adapter/AC/state I can see the state switching between on-line
and off-line, while cat /proc/acpi/event does not see a power-related event.
(After using modprobe button I can see, whether the power-button has been
pressed)
I am using version 20030122
(And while I was looking for the place, where the on-line/off-line events
should be generated I found, that my laptop does not react to echo 2
>/proc/acpi/processor/CPU0/throttling. Doing the same on my tower does
produce the expected result. But I wont try to disconnect the powersupply on
that machine for obvious reasons)
To make the long story even longer: I have seen in the source, that it should
work, and I have seen with cat /proc/acpi/event, that it does not.
Kind regards
Karl
P.S. Sorry for not staying in the thread, but GMX thougt it a good idea to
mark your E-Mail as infected and did strange things to it because of that. I
switched that feature off again.
