Hi!
I got problem with events handling in acpi, it does not recognize any action connected with ac adapter plugging in/off. here is tail -f /var/log/messages.log:

any ideas?
A few, but you leave me guessing. Could you be a bit more precise? Those messages show some events being generated. Are these related to the adapter? If so, you just need to add handlers for them, see the acpid wiki. Also, events which are being handled usually don't generate log messages; to see all events you should try acpi_listen as mentioned in the wiki (this will also show all parts, as in the wiki example, because the log doesn't show which group the undefined action PNP0C0A:00 belongs to).

esacWhat I'm trying to do is to set cpu governor to ondemand when adapter is plugged in and powersave when adapter is unplugged. I saw that actions are undefined so I assumed that acpi is not recognizing actions(even with this:
ac_adapter)
case "$2" in
AC*|ACAD*|ADP0*|AD*))
entries in handler.sh)

Looks like they are handled. acpi_listen shows ac_adapter events in addition to the undefined events that showed up in the log. These are handled by the case in your last quote. Then you have another case statement on $4 to distinguish between plugging (00000001) and unplugging (00000000). If you replace those echo statements by a call to cpufreq-set (or whatever else you can think of), it should work.
