[SOLVED] laptop_mode not switching automatically

vi3dr0 · 2009-09-28 06:29:57

Hi,

I just found out laptop_mode stopped working as it used to. Now when I switch from AC to batt. power I've got to start it _manually_, the same thing other way when I plug AC.

Does anyone has the same problem, or even better, maybe a solution?

have you got laptop-mode-tools installed (extra)?
The daemon is running?

watch if ENABLE_LAPTOP_MODE_ON_BATTERY is set to 1 in /etc/laptop-mode/laptop-mode.conf

Sure it's installed.
Deamon _should_ be running (it's set in rc.conf, and i start it manually with /etc/rc.d/laptop_mode restart).

ENABLE_LAPTOP_MODE_ON_BATTERY is also set to 1, as it has been all the time.

The problem is: Laptop_mode is working correctly (changes cpu governor, hdd settings, dpms times and all the other stuff), but only when I invoke laptop_mode manually (either by sudo laptop_mode or sudo /etc/rc.d/laptop_mode restart). Changes are not made automatically, as they used to.

Long story short: to make it work I've got to restart laptop_mode over and over, every time I plug in/out AC adapter.

Finally, thanks for such a quick response

Cheers

Upon a fresh reboot verify that the laptop-mode daemon is running:

$ ls /var/run/daemons/

If it is listed there then it sounds like your ACPI events aren't updating properly. You can test by having a look at this:

$ cat /proc/acpi/ac_adapter/*/state

...while your notebook is on and off AC power to see if the status changes.

try: modprobe thinkpad_acpi

I'm fairly sure it also needs acpid running.

laptop-mode daemon starts with system correctly.

AC adapter status is read correctly.

thinkpad_acpi module was always there.

i didn't use acpid eariler, however i just installed it, and can't start due to

acpid: can't open /proc/acpi/event: Device or resource busy
                                                                                      [FAIL]

that may be the problem.

running to college late, bye

acpid daemon needs to be started before hal I think.... insert in rc.conf...

The hal daemon starts (in this order) dbus, acpid, hal. So it's best to just insert hal into the DAEMONS line

Well, reinstaling acpid, stopping hal and starting acpid helped indeed.

Thanks for all. Marked as solved.
