[NC10] Kernel 2.6.31

Postby voRia » 27/05/2009, 23:11

There is a new kernel on the repository, version 2.6.31-6 (based on upstream 2.6.31-rc6), taken from karmic and recompiled for jaunty.
It fixes some issues with the intel driver, which works better now.
You can install it with one of the following commands (depending on your architecture, generic is for i386):

Code: Select all

sudo apt-get install linux-image-2.6.31-6-generic

or

Code: Select all

sudo apt-get install linux-image-2.6.31-6-lpia


Alternatively, you can install the package 'nc10-kernel', which depends always on the latest available kernel and its headers files.
This way you will get automatic updates for any new kernel I will add on the repository.

The packages 'alsa-modules' and 'linux-backports-modules' have been removed. They are no more required, because all the changes I used to apply to them (better support for NC10's sound card and rfkill support for wireless card) have been merged in the official kernel development tree and they are shipped in the main kernel package ('linux-image').

Comments and feedbacks are really welcome.

voRia, can you add kernel headers to repository? Headers may be userful for somebody

Sorry for my bad english. :)

The kernel headers are available as 'linux-headers-2.6.30-7-generic' or 'linux-headers-2.6.30-7-lpia'.

There is a new 'nc10-kernel' version on the repository, which automatically installs headers too.

Ok, thank you!

I'm not installing nc10-kernel because it installs alsa-modules and in debian alsa works ok. So i don't want to do a mess in my Debian Sid

First of all: thanks a ton for your work!

I installed nc10-kernel successfully
...but unfortunately the sound-odyssee doesn't seem to be over yet :-(
I can't get sound-recording working reliably for example in skype. In Audacity it worked quite well.
It may very well be my incompetence :-)
I have pulled up all the registers in alsamixer and unmuted the micros, played around with the mic-boost in alsamixer as well to make sure and all that.

Trying to setup audio in Skype, the best result I achieved until now was with:
Mic: HDA Intel (hw: Intel,0)
Speaker: HDA Intel (hw: Intel,0)
Bell/Ringing: HDA Intel (plughw: Intel,0)
Still with this settings audio is only on the left channel and there are some glitches sometimes. Pulseaudio also seems to be dodgy...
Can you give me an example of correct settings in skype?

Cheers,
Niklas

Hi,

installed the 2.6.30-RC7 kernel today.

The intel performance boost is quite impressive, but now my webcam stopped working.

It seems that the kernel recognizes the cam correctly:

Code: Select all

[   10.008996] uvcvideo: Found UVC 1.00 device Namuga 1.3M Webcam (0ac8:c326)
[   10.012707] input: Namuga 1.3M Webcam as /devices/pci0000:00/0000:00:1d.7/usb1/1-8/1-8:1.0/input/input10


But both Cheese and Skype don't show an image... :(

Since I heavily use Skype for video telephony I'll revert to 2.6.28-12.

You're Skype settings are the same as mine and for me it's working.
What are your general sound settings? Are you running Ubuntu Jaunty?
I use the 2.6.30 kernel in Jaunty, but I removed Pulseaudio which seems to cause some problems with my sound setup. I found a step-by-step workthrough for disabling Pulseaudio. I just followed steps 1 and 2, rebooted, checked my alsamixer settings again and now everything seems to work flawlessly.


My Gnome Audio Settings are:

Sound Events:
Sound playback autodetect
Music and Movies:
Sound playback autodetect
AudioConferencing:
Sound playback autodetect
Sound capture HDA Intel ALC272 Analog (ALSA)
Default Mixer tracks: HDA Intel (Alsa mixer)

BTW:
Great work, voRia!!! :)

I've updated pulseaudio on the repository to version 0.9.15, with all the needed libraries. Give it a try.

Besides, there is a new 'alsa-modules' package for kernel 2.6.28-12, based on alsa-driver 20090526 snapshot. It has a better support for NC10 sound, like the 'alsa-modules' for kernel 2.6.30-7.

Indipendently from the kernel in use, with the updated driver and the new pulseaudio the sound seems to be more stable, pulseaudio crashes are less frequent (it happens sometime yet, anyway).

As tscheckoff stated, the new kernel breaks the webcam support. If you need it then stay with the 2.6.28-12 version.

It would be nice to have support for other distros too, like I'm doing for ubuntu.
If you set up a repo for archlinux, please post it on this forum, it would be great! :)

Ok, i will give it a try... can you post me the NC10 kernel .config?

Oh and are there other things in the ubuntu repository besides the kernel? because sounds and webcam and wifi and bluetooth all work out of the box on archlinux :)

Iam workinng on a "settings manager" for the NC10 written in Python... if it is usable i will also add that to the repository.... maybe ill make a plasmoid out of it (since i use kde4) but i am not sure...

I'm using the default configs from ubuntu. Here is the config for 2.6.30-7-generic (based on 2.6.30-rc7).

It's the same on ubuntu, they all work out of the box (on jaunty). Anyway I'm providing separate packages for wireless and alsa-drivers. The former adds support for rfkill function in order to physically shut down the wireless radio, the latter adds a better support for NC10 sound, thanks to the patch by Chris Pockelé.

This is a good new, I look forward to try it as soon as you release it. :)
