      Enable the FN keys (more info and instructions on how to enable and use them here).
    • samsung-tools (only for K/Ubuntu 10.04 - Lucid Lynx)
      Enable full control and configuration of all devices (bluetooth, webcam, wireless, CPU fan, FN keys).
  • Reboot the system to have all changes applied.
  • Have fun!

NOTE FOR KARMIC TO LUCID UPGRADE:
If you have previously installed the packages 'samsung-backlight' and 'easy-slow-down-manager' in karmic, you need to reinstall them in lucid, or else they will not work. Remove the old ones:

Code: Select all

sudo apt-get purge samsung-backlight-* easy-slow-down-manager-*

and install the new versions:

Code: Select all

sudo apt-get install samsung-backlight easy-slow-down-manager

Also, remove the old 'samsung-scripts' package if it's still installed, in order to avoid conflicts with the new 'samsung-tools'.

A little note for the Ubuntu users who are considering to upgrade to karmic and need VGA output: it does not work well yet. When trying to switch monitors, image freezes on both the internal and external screens. I will investigate the problem.

Instead, on Kubuntu everything works perfectly, by using the 'krandrtray' utility.

[voria]

After some tests, it seems the screens' freeze only happens when compiz in enabled.
So, a simple workaround for now is to disable it when VGA output is needed, and everything will work perfectly.

Hello,

First of all thank you very much for the great job you are doing for Ubuntu and NC10

I install NC-10 Backlight but i still can't change the brightness using Fn+arrow up/down.

I'm using Ubuntu Karmic 9.10 on Samsung NC10. I have Bios 04CA.
I am afraid to update Bios. I read the How too and did not understand it

Therefore I prefer the solution with your NC-10 Backlight.

Any Idea to fix the problem ?

[voria]

What kernel are you using?
The current nc10-backlight is for kernel 2.6.31-14 available on main ubuntu repos. Proposed repos have the new 2.6.31-15, but I don't provide updates for proposed packages anymore.

[Nemorox]

Right

I don't know how it happened but I have the Kernel 2.6.31-15

I re-start my NC10 and choosed 2.6.31-14 in the Grub and the Brightness adjustment worked fine!

I tried to get rid off 2.6.31-15 using Synaptic to delete it. But when I restart the computer it logged in using it again ?

How can I suppress this 2.6.31-15 ?

[voria]

To disable proposed updates, go to 'System'->'Administration'->'Software Sources', then in 'Updates' tab and disable 'karmic-proposed'.

To remove the 2.6.31-15 kernel, open the package manager, search for '2.6.31-15' and remove any package found.

[Nemorox]

It worked

Thanks !!

hi,

first, thanks for this wonderful scripts...but i have one problem.

i add the source like your manual above, but i`m getting the following error message:

W: GPG error: http://ppa.launchpad.net karmic Release: The following signatures were invalid: BADSIG 36960FC31E5F36F0 Launchpad PPA for Fortunato Ventre

what is wrong??? what can i do?

thx for hlp. greetings from germany.

[voria]

Install the GPG key with the command

Code: Select all

sudo apt-get install --allow-unauthenticated voria-ppa-keyring

then reload the sources list

Code: Select all

sudo apt-get update

[w00dy]

hey,

after executing

Code: Select all

sudo apt-get install --allow-unauthenticated voria-ppa-keyring

i got this message:

voria-ppa-keyring is the newest version.

and after

sudo apt-get update

is still got

[voria]

Mmm, that's really odd.
Maybe something went wrong during GPG key installation?
Please try to reinstall it with this command:

Code: Select all

sudo apt-get install --reinstall --allow-unauthenticated voria-ppa-keyring

If everything goes well you'll see an 'OK' at the end of the command's output.
Then, reload the sources list with

Code: Select all

sudo apt-get update

Great! You're repo rock. About the backlight though, I can change the backlight now with the nc10-backlight package, but it don't have as many steps as before. It doesn't go really dark, like it used to do in jaunty, when brightness is set at the bottom. Is it suppose to be like that or is something wrong?
