How to ASUS K50IJ - Ubuntu 9.04 Jaunty

[KoKuToru]

Well the laptop originally comes with linux but I wanted ubuntu..
I had some problems and solved them after googeling a lot..

WLAN
run this command and wlan will work

sudo apt-get install linux-backports-modules-jaunty

I think this is not the best solution.. but it works

Compile own WLAN
at http://ubuntuforums.org/showthread.php?t=874097

I can't say it's better/worser..
I did it .. but i can't see any improvement..
compared to linux-backports-modules-jaunty

Sound 1

DONT USE THIS ! USE SOUND 2 !

Sound is more work
Get the ALSA updater script from:
http://ubuntuforums.org/showthread.php?p=6589810#post6589810
Extract it .. and make it executable ! and run it

sudo ./AlsaUpgrade-1.0.x-rev-1.17.sh -di

-di will download and install newest ALSA

Then run this script: (found at https://bugs.edge.launchpad.net/ubun...23/comments/38)

sudo -s
wget ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/misc/hda-verb/hda-verb-0.3.tar.gz
tar xf hda-verb-0.3.tar.gz
cd hda-verb-0.3
make
cp hda-verb /usr/bin
gedit /etc/rc.local

And add this line before "exit 0"

hda-verb /dev/snd/hwC0D0 0x1c SET_EAPD_BTLENABLE PCM

Reboot and your sound will work

Sound 2

wget ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-unstable-snapshot.tar.gz
tar xf alsa-driver-unstable-snapshot.tar.gz
cd alsa-driver-unstable
./configure --with-cards=hda-intel
make
sudo make install

Reboot and it will work
If you used Sound 1 ! Don't forget to change back the edited /etc/rc.local file !

Sound problems
Executing wine stops the sound play back, no idea why.. just restart VLC,Rythmox
or what ever you use..and it will work again..

Sound crackles:
I upgraded my ext3 to ext4 .. and sound was crackeling..
look at the attached image, make sure PCM is at 100%

After every boot PCM is a 0%
Do this:

sudo gedit /etc/rc.local

and add before "exit 0" this:

amixer set PCM 70%

and/or also add it into the autostart (Session-manager) !

Webcam (flip)
Found at: http://radu.cotescu.com/2009/07/31/r...ams-in-ubuntu/

And for copy and past:

sudo -s
cd /bin/
wget http://codebin.cotescu.com/uvcvideo/flip_webcam
chmod +x flip_webcam
flip_webcam 1

And it will be done..

After a kernel update run again:

sudo flip_webcam 1

If left and right is also wrong.. then use the "2"

sudo flip_webcam 2

LCD brightness FN-Keys
(also solves flickering)

sudo gedit /boot/grub/menu.lst

add to this line

# defoptions=quiet splash

this:

# defoptions=quit splash acpi_backlight=vendor

save and do:

sudo update-grub

Reboot.. and it will work

Hi KoKuToru!

Thanks for your advice.
WLAN is working now.

But I still couldn't manage the sound-problem.
I did everything you recommend, but when it gets to the hda-verb command I get the following error-message in the terminal:

hda-verb /dev/snd/hwC0D0 0x1c SET_EAPD_BTLENABLE PCM
open: No such file or directory

Any ideas?

[KoKuToru]

did you installed newest ALSA ?

and i hope you didn't copy&past this:

wget ftp://ftp.kernel.org/pub/linux/kerne...erb-0.3.tar.gz

it need to be like this..

wget ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/misc/hda-verb/hda-verb-0.3.tar.gz

I will edit my post..

[2541]

Of course I tried to copy & paste the 'wrong' link, but found out easily how to download the correct file.

But I didn't use the '-di' option at this command:

sudo ./AlsaUpgrade-1.0.x-rev-1.17.sh -di

I only had set the '-i' option.
After redoing it with '-di' sound started to work!!

So Ubuntu is the very first Linux-Distro to bring a single beep out of my notebook...

btw: Windows 7 RC configures every single piece of hardware in a correct way, except for the webcam (picture is upside down, or with a newer driver left and right side are mixed up) ...

Now the only remaining problem with the notebook is, that the monitor starts flickering everytime I click on the touchpad, but that's a minor issue. Brightness control via FN-keys is working on my machine.

Thanks again for your help und lieben Gruß aus Wien...

You can deactive "Dim screen at idle" in the Energie-settings (you can look at the image.. but it's in german..)
Solved my flickering a little

FN-Key are working right ? hmm.. They wont for me.. grr
I just can set brightness value to 0 and 1
If i look into the file which saves the brightness i can see that the max-brightness is 13 !
And I can set the brightness manually via terminal to 0-13 ...

I tried "sudo apt-get install linux-backports-modules-jaunty" but it could not find the package. What should I do? I'm new at compiling, so any help would be appreciated.

sudo -s
apt-get update
apt-get install  linux-backports-modules-jaunty

And when it still doesn linux-backports-modules-jaunty work... no idea you can downlaod the deb file manually from

Kernel 2.6.15
Kernel 2.6.20
Kernel 2.6.22
Kernel 2.6.24
Kernel 2.6.27
Kernel 2.6.28
Kernel 2.6.30
Kernel 2.6.31

You can get your version with:

uname -r

But apt-gt should work .. ah !
You need a internet connect to do this !!

Thats it xD yeah .. you need to connect your laptop over LAN..
Install the packages .. and then you can use WLAN..
Or you download the file manually (with the links) copy it to
your laptop somehow.. and install it

Posting for a friend...

My friends Asus K50 sound is still not working, even after doing this twice and several other methods. Its the Best Buy model and has a dual boot with Vista 64 and Ubuntu 9.04 X64.

[KoKuToru]

I saw on ASUS page a extra page for a BestBuy version...
Maybe the hardware is different ?

[mikeypizano]

We ran the hardware monitor I installed for him, and its an HDA Intel sound card, and under terminal the one command that tells you the card says VIA.
