Arch on Samsung NC10 ?

joephantom · 2009-04-10 05:48:59

Lately my Samsung nc10 is getting hotter as uptime increase. I'm getting up to 70 degree celsius. What temperature is your netbook running?

Teshadael · 2009-04-14 16:27:10

I've recently updated to the lastest kernel (2.6.29) and I still have no fn key functionality.
I've read the Extra Keyboard Keys wiki article and it mentions testing a scancode using dmesg | tail -5, but after pressing the fn key I get no new messages, which leads me to believe it's still not recognized by the kernel. Has anyone else not gotten their fn key to work with the current kernel yet?

The only key combination that works out of the box for me is Fn + F10 (to disable the touchpad). I don't get any messages using xev or dmesg | tail -5 either, but for example Fn + Arrow Down is correctly interpreted as XF86MonBrightnessDown.

Nice, didn't realize Fn + F10 even worked.
How do you use Xf86MonBrightness? Currently I have other keys bound to xbacklight for the brightness. If I could get the actual brightness keys to work, that would be cool.

Here's my .xindbinkeysrc:

"xbacklight -inc 10"
    XF86MonBrightnessUp

"xbacklight -dec 10"
    XF86MonBrightnessDown

"amixer set Master 10%+"
    XF86AudioRaiseVolume

"amixer set Master 10%-"
    XF86AudioLowerVolume

"amixer set Master toggle"
    XF86AudioMute

Hi alltogether!

I'm quiet new to this forum and also owner of a (not so shiny anymore) new NC10. The posts in this forum helped me a lot to set it up and tweak it a little, so thanks to all of you for your help.

I recently switched to 2.6.29 to try out KMS. Everyone who likes to test it be warned: some things do not work until now. One thing among others is setting backligh brightness with xbacklight. This bugreport gives the impression, that there are problems in deciding, which kernel module should offer backlight support. On the other hand there is a pretty cool hack for the NC10 mentioned (which I wouldn't try on other systems ) setting the backlight directly via setpci:

setpci -s 00:02.1 F4.B=XX

with XX ranging from 00 to FF.

Useful only in emergency cases I think but cool at least ...

Best regards,
Michael

Hi folks,

got my NC10 two weeks ago. Almost everything is running fine with Arch and Xfce.
But there is still one problem which I can't get get rid of... power consumption is the word

At the moment powertop says its 10.0W... with btusb, vcvideo, sky2 unloaded and `xbacklight -set 10` (so very low).

I was wondering how people managed to get levels like that:

I get from 7.9 to 8.9W, with 50% xbacklight. Almost 8 hours of battery.

scooby wrote:

Powertop says I am using 8.1W at the moment.

So what did you actually do or enable to get it that low? And which program/script are you using to manage it? (such as laptop-mode)

I'd really appreciate any help on that

Is any one experiencing trouble with audio after updating the kernel to 2.6.29.1-4.
It was working great before I just updated but now alsamixer it only shows pcsp.

$: cat /proc/asound/cards 
0 [pcsp]: PC-Speaker - pcsp
 Internal PC-Speaker at port 0x61

I can hear the audio but it has alot of static and is the volume is extremley low.

Any one have any thoughts please?

Thanks

Crocomo · 2009-04-21 14:52:00

Nope. Works fine for me. Updated yesterday.

Are the modules loaded?

lsmod | grep snd

It seems to be:

...
snd_hda_intel          25384  0 
snd_pcsp                9164  0

snd_hwdep               6904  1 snd_hda_codec
snd_pcm                67992  4 snd_hda_intel,snd_pcsp,snd_hda_codec,snd_pcm_oss
snd                    51460  11
snd_page_alloc          8092  2 snd_hda_intel,snd_pcm
...

I've tried loading the modules manually aswell but alsamixer still only shows pcsp.
I'll do a bit more googleing, hopefully I can find some positive results

* Edit: Strange results.

I installed OSS as a temporary fix, didn't like it tho (headphones wouldn't mute the speakers) so removed and went back to ALSA - Now my audio is working great again.
I also removed the pscp.ko module off the system (I know I can blacklist) but I never use it.
I'm happy again

Yet again, after another Kernel update, I'm having the exact same problems as in my last post - above.

Does any one know why alsa automatically uses pcsp, even when both modules are blacklisted in rc.conf?

It gets really annoying after updating the Kernel, to have to spend an hour or two tinkering around, rebooting, tinkering a bit more just to get my sound to the state I left it at. As of yet I can't get it working again.

Mr.Cat · 2009-05-08 20:21:25

kYd. You may try to add "!snd_pcsp" to "MODULES = (..." in "/etc/rc.conf". That fixes all sound-related issues for me (and yes, I am a pc-speaker-hater). This trick is also mentioned in wiki (http://wiki.archlinux.org/index.php/Beg … igure_ALSA).

Thanks, I had already done that; just seems with every Kernel upgrade it likes to mess with the speakers somehow and ignore the blacklisted sound devices.

I managed to get it working this time by going through the process of configuring the sound card again with alsaconf.

Mr.Cat · 2009-05-09 15:18:37

kYd, that is strange. Though, my system has not gone through a kernel update yet. Do you mean, that even with !snd_pcsp it gets loaded?

Mr.Cat · 2009-05-09 15:38:06

Btw, all who wrote about watts:
Did you write "long term" value or not?

Mr.Cat · 2009-05-09 15:49:15

As for me I use laptop-modes usb autosuspend feature. With bt disabled (!btusb), powertop does not complain.

Mr.Cat · 2009-05-09 16:21:35

Also, do you, guys use ath5k for wireless? Did anyone try to set up madwifi (madwifi might have better powersaving options)?
Also I wonder, how to enable power management for wifi.
lspci -v states, that it has "Power Management version 2", but iwconfig states, that power management is disabled by default.

Also, there is a strange thing about resuming after suspend/hibernate. Right after resume (according to powertop) BIOS claims not to have c2 and c4 cpu c-states, but in several minutes the support for them returns.

Barghest · 2009-05-16 08:03:52

Hi Mr.Cat,

yes I use ath5k. With madwifi I didn't get my wireless working (don't know why).

You tell about problems you have after resume. Do you use a custom kernel? For me neither s2r nor s2d work. S2d hangs with a blinking cursor while goging down and resume from s2r doesn't work at all. I hear the HD is spinning up but nothing happens.

nonickknown · 2009-06-02 08:27:40

hi
is anybody out there whos got a running hsdpa/3g modem? i'm not able to find out how it works. My favorite program is umtsmon but if anyone got a wvdial.conf or something else am happy too

i hope my english isn't too bad thank you

brendan · 2009-06-09 17:13:08

a few questions:

How do i set the backlight in xfce? I can do it with :
setpci -s 00:02.1 F4.B=FF etc... but it would be nice to do it with the keys like in xubuntu

How do i get the power button to display the xfce chooser thing when pressed?

and more of an arch question than an nc10 issue, what group should a normal user be added to if I want him to be able to shut the machine down?

I've fixed the user shutdown issue by adding myself to the power group.

Good point !
xbacklight comes with package xorg-server-utils, I corrected the wiki.

Mogger · 2009-06-09 21:53:18

I think xorg-utils has xbacklight.
