APM and ACPI problems on Samsung R518

Aksem · 06-27-2016, 03:12 AM

Hi. I have Samsung R518( Intel Pentium Dual Core T4200 + Intel GM45 Express ). I changed hdd with ssd and installed Linux(OpenSUSE Tumbleweed Linux 4.6.2 ). But there are some problem with acpi and apm:
1.Fn buttons works only with acpi_backlight=vendor parameter.
2. Laptop works normal only with enabled charging. If i try disconnect it, laptop not responding(I/O errors and hdd 100% load).
After that i tried 'acpi=off apm=off' boot parameters. With them laptop works good(even without charging) but resolution is 1024x768(should be 1366x768).
I tried different combinations of parameters ( https://wiki.ubuntu.com/DebuggingACPI ), but any of them didn't help me.

You've left us short on details but I gather the PC is a bit dated.

APM was abandoned and ACPI developed because APM didn't work. Disable APM unless you really need it. ACPI links events to scripts (in /etc/acpi/). Run acpid with '-l' and run 'tail -f' on syslog and you should see acpi events logged as the box notices them. You can link working ones to scripts that you hack, cripple or cobble together to work. Don't forget about the power manager in every major window manager. That can be useful, or possibly duplicate the work of ACPI.

I disabled apm(now kernel parameters is only 'apm=off acpi_backlight=vendor') and Plasma power manager(powerdevil). After that I tried again different parameters for acpi, but any effect.
In /etc/acpi/ is only thinkpad-radiosw.sh . Also I tried to find errors in system log( http://paste.opensuse.org/32107408) , but i didn't find any.

it works like this: stop acpi & immediately run a

Code:

sudo acpid -l

In a second terminal run

Code:

tail -,f  /var/log/messages

Then operate the lid button, for example & see if it's noted in the log. Note the name exactly (e.g. Lidbtn) because you need that for the event. Then take an event that looks close and hack it for your box. Point the event to a script, and tweak the script to run and do it's thing for you. Google will be of great use here. Repeat for other events/actions

Other things to do might be to look your machine up on linux-laptop.net and read up how others managed with it.

But how should I stop acpi?(I know only one way, as boot parameter. But with acpi=off system doesn't even start).

On linux-laptop.net I haven't found this laptop model.

To stop ACPI:

Code:

sudo skill -9 acpid

Aksem · 07-18-2016, 02:39 AM

Code:

user@linux-xu6r:~> tail -f  /var/log/messages
tail: cannot open '/var/log/messages' for reading: No such file or directory
tail: no files remaining

When I tried monitor logs with journalctl, I found this lines(after operating the lid button):

Code:

лип 18 10:30:11 linux-xu6r acpid[14398]: received input layer event "button/lid LID open"
лип 18 10:30:11 linux-xu6r systemd-logind[903]: Lid opened.

Sorry, that is pkill and not skill. This mailer auto MIScorrects spellings and if I don't spot and uncorrect it, the wrong thing goes out.

Your lid button event was registered but there's no rules using it. an entry in /etc/acpi/events should point at a script in /etc/acpi that tells the box what to do. That's how acpi works. You need the event name found in the log in the "events" entry and it all takes off from there.

Aksem · 07-24-2016, 03:47 AM

What I tried to do:
1. Load system.
2.

Code:

sudo pkill -9 acpid

3.

Code:

sudo acpid -l

4. Close, wait for sleep and open a laptop.
4.

Code:

sudo journalctl -b

Sorry, but I can't find event names.

I'm trying to read this without the use of my paralysed arm, so there's no way I can make sense of a paste that long.. Let the PC do it.

Code:

cat /path/to/log |grep -ie 'event' -e 'registered'

if that shows nothing, it's not seeing events. Clearing the log of past events makes this much handier.

EDIT: journal to seemed to work with your box and found events. If suspend or hibernate works, something is doing acpid. It may be systems.

Aksem · 09-04-2016, 03:59 AM

If suspend works(systems acpid?) and I have in logs such message '04 10:54:22 linux-xu6r kernel: ACPI : EC: 1 stale EC events cleared', can I disable this system ACPI?

business_kid · 09-05-2016, 12:53 AM

Yes, just stop acpid. But you stop cooling the CPU so you can't run like that! acpid links events to scripts and the solution is to tweak them for your box usually.

Aksem · 09-05-2016, 12:19 PM

But what I should doing, if I can't names of events get? Or I do something incorrect?

business_kid · 09-06-2016, 01:16 AM

To get names of events, do the following

- As root, kill acpid and restart it as acpid -l. That logs events to syslog.
- In a terminal, run ' tail -f /var/log/messages' or whatever the main log file is.
- Cause ACPI events and see what is logged. Try to suspend, block ventilation briefly to see if the fan charges speed, etc.
- You can always look in /etc/acpi/events to see the events it is looking for

Aksem · 09-06-2016, 03:07 AM

I tried to use acpi_listen and I've got some logs:

Code:

ac_adapter ACPI003:00 00000080 00000000
battery PNP0C0A:00 00000080 00000001

It's events names, yes?
Then my laptop again didn't respond.
But in /etc/acpi/events is only thinkpad file with those content:

Code:

# forward acpi events to the thinkpad handler (bluetooth etc.)

event=ibm/.*
action=/usr/lib/acpid/thinkpad_handler "%e"

Can I now create empty action for ac_adapter event or change standard for example?
