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.

Echo disk /sys/power/state broken

Hello all
After recent update after long time my hibernate was broken
#echo disk > /sys/power/state
does black screen and standby of display later. But system block not turned off, e.g. fans are worked.
#echo mem > /sys/power/state
is working. Before update echo mem not worked right
#cat > /sys/power/state
freeze mem disk
Install old kernel not resolve the problem.
I try to do debugging hibernation with https://www.kernel.org/doc/Documentatio … ugging.txt
echo freezer > /sys/power/pm_test
echo disk > /sys/power/state
worked
but
echo devices > /sys/power/pm_test
echo disk > /sys/power/state
not worked
If the "devices" test fails, most likely there is a driver that cannot suspend
or resume its device
Who can broke hibernation process?

Black screen upon wake from sleep when I change power state while in sleep

Hi,
I'm having this problem where my MacbookPro won't always wake from sleep.
OSX is 10.6.3 and fully updated.
I've done a lot of troubleshooting, and I can now replicate the issue 100%:
1 - Put the MacbookPro to sleep by closing lid
2 - Change power source (from plugged-in to battery or vice versa)
3 - open lid - MacbookPro will wake, but stays at black screen and is unresponsive.
Only if I change power state while sleeping will this issue show. Anyone else experincing this issue, and anygot got a clue on what to do?
regards,
Lasse

I've seen the same issue after upgrading to 10.6.3. I have a one year old MacBook Pro. I would have the screen be black after coming back from sleep or hibernate (tried both).
The workaround I found is to close the lid -almost- all the way and then immediately open it back up again, like I am catching the Mac going back to sleep and then changing my mind. For whatever reason, this has been reliably solving my issue for the last couple weeks reliably.
Only other oddity I noticed is that immediately after upgrading OS X told me that my one year old battery needed to go in for servicing...
Anyway, now all looks right with the world assuming you don't mind a quick close/open cycle.. Lovely...

[solved] difference: echo "mem"/"standby" /sys/power/state

what's the difference between "mem" and "standby"?
i see no difference except the mouse light remains on when running "echo standby > ...".
some expanations?

/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....

Getting Device Power State using Windbg Extension

Hi All,
I want to develop an application and debugger extension to get the current power state of my device. I know in the application side, p can use the SetupAPI to get the current power state of the device. I want to accomplish the same using WinDbg extension.
Can i use the SetupApi in Winfdbg extension? If not, what is the other way to do that?
Thanks in advance.

SetupAPI can be called from windbg extension, but it will act on the host (debugger) side - not what you expect.
The power state of the device is in device_object-> _DEVOBJ_EXTENSION -> _DEVICE_OBJECT_POWER_EXTENSION.State field.
(this is undocumented secret, so don't tell anyone!)

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

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

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..

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.

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 .

/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

Because :

And also because as forum moderator, we have to keep the boards as clean as possible. For you the problem might be new, but for many users here, they have seen these types of threads many times which have also been answered over and over again and also documented in the wiki. The wiki is a resource that has been created by the collective efforts of the Arch users - present and past. Make use of it.
As a general rule, if you have an issue, search the wiki, then the internet, then the forums for similar threads and if you still have problems then post a thread detailing what attempts you have made in order to fix the problem. That way, people don't give you options that you have already tried and know that they don't work.
In addition, please go through the forum rules to familiarize yourself with the basic rules and policies of the Arch forums.

Using wait or sleep without a thread

Is there any method to do the equivalent of a wait or sleep without using threads?

You have a single-threaded application executing, and
you want to pause it at a given location for a given
period of time. If you call sleep, you give up
execution, which you don't want to do.What do you mean by not wanting to give "up execution"? It is the scheduler of your OS that decides when your program executes or not. Your code snippet does nothing but burn processor time (incidently pretending to the scheduler that it actually has something useful to do) which could be well used by some other process running on the computer. Use Thread.sleep instead, thats what it is there for. If you want to somehow affect the amount of processor time that the scheduler allocates to your process you will be better served by increasing its priority.
having my skill and/or intelligence mocked Well, I have certainly not mocked your skill nor your intelligence, god knows that I have on occasion presented poor solutions in this and other forums, but lets not dwell on that...

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.
