Samsung R518 Fn+* problem.

Postby exploit » 14/03/2010, 17:03

Hi everyone.
I have Samsung NP-R518-DA09UA notebook with latest 04LC BIOS version, and known problems with it.
It is unable to adjust backlight with Fn+Up\Down, unable to toggle WiFi with Fn+F9, unable to toggle backlight with Fn+F5. Fn+Left\Right (changing volume) and Fn+F6 (mute) are working.
I have a fresh installation of Ubuntu 9.10 Karmic Koala on it with Gnome 2.28.1

Wow, it's great.

So, i made this:

Code: Select all

# Repository URL: https://launchpad.net/~voria/+archive/ppa
# Instructions:

    * Add the repository to the sources list and enable it
          o Ubuntu:
                + Go to 'System'->'Administration'->'Software Sources'.
                + Click on the 'Other Software' tab, then on 'Add...'.
                + In the 'APT line:' text field, insert ppa:voria/ppa, then click on 'Add Source'.
                + Click on 'Close' and when asked click on 'Reload'.
                + Open a Terminal and use the following command to install the GnuPG verification key for the repository:
                  Code:
                  sudo apt-get install --allow-unauthenticated voria-ppa-keyring
          o Kubuntu:
                + Open the 'K' menu, click on the 'Computer' tab, then on 'KPackageKit'.
                + Click on 'Settings', then 'Edit Software Sources'.
                + Click on the 'Other Software' tab, then on 'Add...'.

                + Close KPackageKit.
                + Open a Terminal and use the following command to install the GnuPG verification key for the repository:

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

          o From the Terminal, use the following command in order to update all the packages at the latest versions:
            Code:
            sudo apt-get update && sudo apt-get upgrade
    * Install the important packages
      Use your favourite package manager to install the following packages:
          o samsung-backlight
            Enable the screen backlight support for netbooks that don't have a proper support.
            On Samsung NC10 it's not needed if you are using BIOS 11CA.
          o samsung-scripts
            Enable the FN keys (more info and instructions on how to enable and use them here).
          o samsung-wireless
            Enable the wireless card, on netbooks shipped with a Realtek card.
    * Enable laptop-mode for a better power and hard disk management
          o Follow instructions in this thread.
    * Reboot the system
          o Reboot the system to have all changes applied.

Is it OK ? Or i need to remove or add something?
And, tell me please, how can i do update of your repository ? I need it to not to do something wrong ))) ::)

Yes, those are the instructions to add the repository to your system.
However, you don't need to install the 'samsung-wireless' package, since it's for netbooks shipped with Realtek wireless card, while your R518 is shipped with an Atheros wireless card (working out of the box).

Since you have added the repository, the package manager will check for new updates automatically, on a daily basis.
You can also check and install updates manually by using the package manager, or by using this command in a terminal:

Code: Select all

sudo apt-get update && sudo apt-get upgrade

Anyway, just for the record, the new packages on the repository are building yet, they are not yet available for installation.

Hello.
On my R518 toggling backlight and WiFi with Fn + F5 F9 started to work after a few

Code: Select all

sudo apt-get update && sudo apt-get upgrade
. Showing the backlight adjustment slider moves, but the backlight still remains on the same level.

Did you install 'samsung-backlight'?
Also, try to add the option 'acpi_backlight=vendor' to the GRUB kernel command line.
Instructions to do it:
- Open the grub configuration file:

Code: Select all

sudo gedit /etc/default/grub
- Change the line:

Code: Select all

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
in:

Code: Select all

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor"
- Save and exit.
- Update the GRUB against the new config file:

Code: Select all

sudo update-grub
- Reboot.
