@Jristz
what is your kernel version?

Jristz · 2013-02-21 04:49:45

kernel: 3.7.9-1-ck
powerdown: 20130219
File system: jfs
My wirelles is called: wlp1s0

the interface name problem will be solved in the next version

what is your result of running ls /sys/class/backlight

I reinstalled powerdown.
Now, on AC without any power* command:

[root@localhost i-sty]# powernow

I havent any files under /sys/module/i915/parameters/
Under /sys/class/backlight I have two folder, acpi-video0 and intel_backlight.
But, with pm-utils package under intel_backlight I had a file named brightness, now I havent, (I removed pm-utils because was in conflict with powerdown)
My kernel line

echo    'Loading Linux  ...'
$6e14 ro  quiet pcie_aspm=force i915.i915_enable_rc6=1 splash

------------------------
Edit:
If I modified the /sys/class/backlight/acpi_video0/brightness file the brightness isnt modified.

You can append that to the grub line:
i915.i915_enable_rc6="x"
. Remember to comment that line in powerdown script!
Ps: "x" is your preferred value

I already added this flag to the kernelline.

yes, and both have different max values

taylorchu · 2013-02-21 23:40:31

please remove "acpi_osi=Linux acpi_backlight=vendor" from grub.

Jristz · 2013-02-22 02:18:50

remove and now

[powerdown] cannot write powersave to /sys/module/pcie_aspm/parameters/policy

ls /sys/class/backlight

acpi_video0  psb-bl

and unable to control brightness throw the normal way on xfce, and powerdown not low brightness

PD: the 2 parameters on the grub are recommended for my pulsbo (gma500) video card

taylorchu · 2013-02-22 04:59:27

1. add "pcie_aspm=force" to grub
2. can you try "powerdown" then "powerup"? I think the brightness will change. also please paste the powernow msg before and after you run the command.

o
but in both cases the brightness in my monitor not change

but I discover that psb-bl have a value of 1 to 100 and THIS is the responsible againt bightness changes NOT acpi_video0

Great, absolutely great and totally kiss.

Machine: Dell XPS L702X Nvidia GT555M, no Optimus.

Windows 7+Dell Power Extender ~ 3.5 hrs
Arch(bang) clean install ~ 2.5 hrs
Arch(bang) optimized ~ 5 hrs !!! (And with wifi working, minimum brightness, stock hard disk optimizations)

How do you optimized? I also have a Dell laptop. Dell 5520 i5 with IGP.

Optimized I mean, I installed Linux-ck from graysky's repo (sandybridge) along with the proper nvidia binary blob, xfce4, a custom 20-nvidia.conf in /etc/X11/xorg.conf.d/ directory and last but not least... powerdown. Actual maximum capacity from the battery is 80 Wh, after a year of moderate usage still performing really well.

twilight0 · 2013-02-22 19:41:40

I pressume it will consume much less power if I had an SSD inside, as of now it has dual HDDs.

taylorchu · 2013-02-22 20:27:33

@everyone
backlight should work now. please update

Jristz · 2013-02-23 05:50:49

Eyup, finally brightness work as spected

thanks tailorochi

I-sty · 2013-02-23 13:11:12

Yes, thanks.
Brightness is work.
But:

[root@localhost i-sty]# powerup
[powerdown] cannot write 0 to /sys/module/i915/parameters/i915_enable_rc6
[root@localhost i-sty]# powerdown 
[powerdown] cannot unload module bluetooth

Thanks.
I tried the ck kernel.
The bigger battery is the best way to a longer battery time;)
I have the default 48Wh battery from the Dell.

Hello,

I've added this to disable power on lan on the ethernet interface :

for f in /sys/class/net/en*; do /usr/sbin/ethtool -s ${f##*/} wol d; done

To resume :

for f in /sys/class/net/en*; do /usr/sbin/ethtool -s ${f##*/} wol g; done

This adds ethtool as a dependency.

taylorchu · 2013-02-25 03:21:46

wol is disabled by default.

mityukov · 2013-03-25 17:38:49

Not sure if it's connected to powerdown at all (though, it adds some pm-utils wrapper, right?)...

The issue is that I can't connect to any wireless network after resuming from "Suspend to RAM". The NetworkManager keeps saying something like "Unable to connect {network_name}" and that's all.

Note: tried to fire `sudo systemctl restart NetworkManager` command -- it doesn't help.

Here's some dmesg output (for what I believe related to sleep/resume): http://pastebin.com/feyiDgRc

P.S.: can't really say if wifi adapted was turned on or off, after resume. What command should I use to verify that?

Why don't you just uninstall powerdown to see if this resolves your issue?

I can't be sure, but when I installed powerdown, there were some packages I had to remove. So, I'm simply afraid of breaking things by removing powerdown

orschiro · 2013-03-26 12:41:06

@mityukov

The only conflict exists with pm-utils which is not really system-relevant.

taylorchu · 2013-03-26 17:03:58

@mityukov
1. your log tells nothing about the state of networkmanager. it looks like it is fine after resume, because i saw you can still auth to some ap
2. powerdown really does not have any serious dependency
3. how do you suspend in detail?
