/proc/acpi/fan empty

Hey there...
I have been trying to get at least some of the Power Management working under Linux, but haven't been too successful. Most important for me:
Spin my fan down. The temperature seems to be at 22°C, so no cooling should be needed?
Unfortunately I don't have any entries in /proc/acpi/fan, does this mean, it can't spin down? Or do I need to load any specific modules for this?
Maybe related: There is only one "trip_point" defined in thermal zone:
[root@frank /]# cat /proc/acpi/thermal_zone/THRM/temperature
temperature: 22 C
[root@frank /]# cat /proc/acpi/thermal_zone/THRM/state
state: ok
[root@frank /]# cat /proc/acpi/thermal_zone/THRM/trip_points
critical (S5): 110 C
[root@frank /]# cat /proc/acpi/thermal_zone/THRM/cooling_mode
<setting not supported>
cooling mode: critical
Btw... the CPU is an AMD Turion64, and its frequency is scaled down by cpudyn.

yes - I have 3 machines that don't detect fan settings... the i2c+lm_sensors stuff should handle that, but I never bothered...

Button/lid (no /proc/acpi/events?)

I must be missing something obvious but it seem that when I close my laptop's lid, the button/lid section of handler.sh is not triggered. I have acpi running fine, it even seems that other events are successfully triggered (like ac_adapter), but not button/lid. Essentially I'm trying to run 'powersave -u' when I close the lid.
Help please?

Thanks for the reply. It seems like this might be part of a bigger problem though, because I don't seem to have a /proc/acpi/event. What I have in /proc/acpi are ac_adapter, battery, button, embedded_controller, fan, power_resource, processor, thermal_zone, and video.
Also, when I start my computer, Arch says that the acpi daemon started successfully. But if I stop it (also successfully) and then try to start it again, it always fails with "acpid: can't open /proc/acpi/event: Device or resource busy".
Here's some sample output from /var/log/acpid which doesn't seem to be very useful. The exiting lines are probably me manually stopping acpid, although it never starts up again unless I reboot..

Where is my /proc/acpi/video interface? Can't find it!

Hello!
I'm using a custom kernel. (2.6.23.8) For my xorg config I need a /proc/acpi/video interface (the nvidia driver need this interface).
I searched in the kernel config, but in Power Management / ACPI there isn't a "Video" Option.
How can I active this interface?
Thanks for your help!
Best regards,
Flasher

Hello,
I had the same problem a while back. You have to go into Device Drivers / Graphics Support, and turn on the first option, "Backlight & LCD device support". Under that option, choose "Lowlevel backlight controls". At this point, the video option should magically appear in the ACPI section.
Works for me. There may other dependencies I don't know about.
HTH,
peart.

Missing battery files in /proc/acpi/battery

I'm trying to employ this script:
http://mindspill.net/computing/linux-no … y-warning/
to get low battery warnings. It draws info from files like
BAT_STATE="/proc/acpi/battery/BAT1/state"
BAT_INFO="/proc/acpi/battery/BAT1/info"
but folder /proc/acpi/battery/ does not exist in my system. I do have /sys/class/power_supply/BAT0/ folder, but it does not containt 'state' or 'info' files.
What should I do to make this work?

Maybe I am being a bit thick, but am not well versed in scripts.
I already modified the script to use notify-send rather than zenity

then

BAT_DISCHARGE=`awk '/rate/ { print $3 }' $BAT_STATE` # Discharge rate in mA.
BAT_WARN=`awk '/warning/ { print $4 }' $BAT_INFO` # Warning level in mAh.
BAT_LOW=`awk '/low/ { print $4 }' $BAT_INFO` # Low level in mAh.
BAT_ALERT=$(( ( ( $BAT_DISCHARGE / 60 ) * $BAT_ALERT_TIME ) )) #+ $BAT_WARN )) # Work out the charge that will have been used in $BAT_ALERT_TIME minues (and add the warning level charge as a buffer zone).

However, I suppose changing it to use acpi -V would involve more in-depth modifications which I am not sure of.

/proc/acpi/event: Device or resource busy

Hi
ACPI has been working fine on my Acer Travelmate for a long time - but suddenly it broke. I can't start acpid deamon - I get the following error:
acpid: can't open /proc/acpi/event: Device or resource busy
Does anybody know how to fix it?

Hello, I have the same problem, but I think (not confirmed yet) that the solution of putting acpid before hald might work... (i can't restart this notebook right now...)
Just posting this because i used "lsof" to find what process uses the /proc/acpi/event file... so it would help you to find why you can't access it even when acpid starts before hald....

/proc/acpi/video/* is gone [SOLVED]

Hello!
I noticed my precious directory was missing, when i tried manually set the LCD brightness with echo value > /proc/acpi/video/my/videoadapter. I have installed laptop-mode tools for managing the brightness when plugged in AC and when on battery.
Thanks.
Last edited by nybegynner (2011-02-13 20:56:50)

Thanks, buddy!
I'm now controlling the brightness with these settings:
BATT_BRIGHTNESS_COMMAND="echo 3"
LM_AC_BRIGHTNESS_COMMAND="echo 24"
NOLM_AC_BRIGHTNESS_COMMAND="echo 24"
BRIGHTNESS_OUTPUT="/sys/class/backlight/acpi_video0/brightness"
(Note: The levels of brightness goes from 0 (least bright) through 24 (most bright)

No battery identified in /proc/acpi/

After the last couple of kernel updates, I no longer have a BATx folder inside /proc/acpi.
I used it to pipe the results to a little script I use on my statusbar, which keeps track of my memory usage, battery left, etc.
The strangest thing is that dmesg acknowledges the battery is there, and acpi returns the correct percentage and everything. It's just gone from /proc/acpi.
Anyone else had this one happen?
My laptop is an Acer TimeLine 1410.
dmesg | grep battery
[ 5.630145] ACPI: Battery Slot [BAT1] (battery present)
acpi -i
Battery 0: Full, 100%
Battery 0: design capacity 4400 mAh, last full capacity 4264 mAh = 96%

Using /proc to store ACPI information has been discouraged and deprecated since 2.6.24. The same data is available in /sys now and interested parties can (should) subscribe to ACPI events from the kernel via netlink.
https://bugs.archlinux.org/task/25845
acpitool upstream needs to fix this.

Klaptop using /proc/acpi/sleep instead of /sys/power/state

This is a problem in kde since it disables most of the features of klaptop. In other words for me at-least kde cpu frequency scaling, standby, suspend do not work through klaptop since it seems to use /proc/acpi/sleep instead of /sys/power/state which is the only thing available in the new kernel. I am not sure if this is a kde problem, my kernel problem, or just simply my particular problem.
Is there a way to fix this.
Thanks for the help,
Matt

It also seems kde is not reading the current cpu frequency correctly. It seems to use/proc/cpuinfo instead of /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq to get the current frequency. In addition when clicking setup helper applications under ACPI Config in klaptop I get:
The /opt/kde/bin/klaptop_acpi_helper application does not seem to have the same size or checksum as when it was compiled we do NOT recommend you proceed with making it setuid-root without further investigation
Are other people having these problems as well or is this unique to me.

Deprecated /proc/acpi/

Hello,
Sorry, my english sucks.
Do you recommend to keep these options enabled in the kernel?
Deprecated /proc/acpi files
Deprecated power /proc/acpi directories
Deprecated /proc/acpi/event support
or the related acpi pkgs in Arch are updated for use /sys/ ?

Most acpi modules should have switched to sysfs by now but you'd have to read the documentation for the acpi-module you want to use.
I'd still keep it around. It doesn't hurt and it's shorter than /sys/devices/platform .

2.6.24 and /proc/acpi/battery

Hi,
Since the update to 2.6.24 (I now run it, pulled it in from testing) the procfs for acpi was deprecated. I think we should keep the two next options in the arch kernel.
# CONFIG_ACPI_PROCFS is not set
# CONFIG_ACPI_PROCFS_POWER is not set
I think the above should be set since quite some few applications depend on /proc/acpi/battery and /proc/acpi/ac
And even on 2.6.24 there still is a /proc/acpi directory filled with some things, so it's not so very "deprecated" if despite the fact CONFIG_ACPI_PROCFS is not set, there still exists such a directory.
Cheers!
ps. the app that is broken for me is kde's klaptopdaemon from kdeutils, 3.x.

cool, sorry, I completely forgot about the bugtracker. It's fixed now in -2 by tpowa. waiting for x86_64 testing to get bumped. can be closed! thanks

/proc/acpi/button does not exist.

/proc/acpi/button does not exist. Any ideas?
or, anyone knows which module is the owner of /proc/acpi/button?
Thanks!

I am having the same problem, even with a stock kernel. There is no power button
device and therefore acpi_listen does not detect putton press events. I am on a
Thinkpad T420s, which used to work until a recent reinstall. Here are the

I have been unable to trigger an event when the power button is pressed on my laptop.

That output indicates the power button is recognized by the kernel, but it have no idea what i should put in /etc/acpi/handler.sh to shutdown the laptop when the powerbutton is pressed.

button/power PWRF 00000080 00000002
These are the arguments passed to the handler script ($1 to $4).
handler.sh from acpid package:
case "$1" in
button/power)
#echo "PowerButton pressed!">/dev/tty5
case "$2" in
PBTN|PWRF) logger "PowerButton pressed: $2" ;;
*) logger "ACPI action undefined: $2" ;;
esac
Replace the logger "PowerButton [...]" command (which is responsible for the message.log line you quote) with a shutdown invocation.

Fan problem. hot notebook

I'have a problem with my fan.
It never starts and my notebook become so hot that i can't put my hands on.
I get the temperature with acpi and lm-sensor but my fan doesn't start.
Any idea?

I've an Acer Travelmate 3012
with win and my previous installation of gentoo fan work very well
I've loaded the acpi deamon and the sensors daemon.
But in my /proc/acpi/fan I have only empty files...

AMILO pa 3553 acpi problem

Hi!
I've recently switched from Ubuntu to Arch and been tinkering. After getting a (barebone) graphics environment up I began running into problems. My laptop (Fujitsu Siemens AMILO pa 3553) began overheating badly and the fan, while on, didn't increase or decrease in speed. Just humming away at a leisurely and insufficient pace.
So I thought I would fix the problem by forcing the fan speed, which is where I realized my /proc/acpi/fan was missing! It was there when I used Ubuntu and just to make sure I wasn't misremembering I rechecked the specs of my laptop on the internet. It _should_ be acpi compliant.
I've tried running sensors-detect (which assure me that k10temp is correct and loaded and all I need) and no matter what I do, it simply doesn't seem to register anything else than the temperature of my (2) cpus and my AC adapter.
I'm out of ideas. You guys have any?

Yes, yes I did.
As far as I can read the wiki assumes that the OS acknowledges the existence of the fan. I have no problem manually configuring a fan, the problem is when for some reason it won't detect the ACPI for the fan. It worked under Ubuntu and I can read on the internet that my laptop is ACPI compliant, so I know it should be possible for Arch to do this.
