"If you really need them, you can manually download them from the repository"

I need the backlight module. Could you please explain of to download them from the 12.10 repository?

Go to the repository page (link is above, in the header of this forum), click on "view package details", download the .deb file you need and install it on your system with a double click on it.

Open a terminal and type :

Code: Select all

sudo apt-get install samsung-backlight

Hi all,

I just discovered samsung-tools, so I decided to install them on my Kubuntu 12.04, Samsung RC530. I followed the instructions, and I get no errors in the kernel log:

Code: Select all

laptop:~$ grep samsung /var/log/kern.log
Jun  4 08:40:33 laptop kernel: [   12.599491] samsung_laptop: detected SABI interface: SwSmi@
Jun  4 08:40:33 laptop kernel: [   12.599493] samsung_laptop: Backlight controlled by ACPI video driver


but the Fn shortcuts appear not to be working. If I type:

Code: Select all

samsung-tools -i


I get:

Code: Select all

  File "/usr/bin/samsung-tools", line 40
    class Backlight():
                    ^
SyntaxError: invalid syntax


EDIT: If I use a different version of python, I get:

Code: Select all

laptop:~$ python2.7 /usr/bin/samsung-tools -i
Backlight control: unable to connect to session service!


Same goes for any samsung-tools command.

Any advice on how to solve this would be very appreciated!

Claudio

Samsung-backlight won't work anymore with 3.5.0-32 kernel

Postby martini » 07/06/2013, 12:17

Samsung-backlight won't work anymore with 3.5.0-32 kernel on Samsunp NP300.

UPD: it works again after linux-tools installed and (or) reboot... Some fuzzy troubles... Sorry for spam here.

Hi voRia,

I'm using your great tools on my Samsung R580 laptop for years now and I'm happy with it. Thanks for your effort!
Here comes my experience with your hint for activating brightness control on a Ubuntu 14.04 LTS.
Since I utilize the proprietary nvidia graphics driver with my GeForce GT 330M chipset, the grub cmd line trick does not work for me. (Using nouveau driver the backlight control works for me.) Trying to edit the Device section in xorg.conf file seems kind of pointless hint for most users because latest *buntu distributions do not use these files per default.
So here's what I did to manage to get brightness control working:
  • Start "NVIDIA X Server Setting" from menu or type in a terminal:

    Code: Select all

    /usr/bin/nvidia-settings # [Return]
  • Select "X Server Display Configuration" from the left hand menu.
  • Push button "Save to X Configuration File".
  • Push button "Show preview...".
  • Add the line

    Code: Select all

        Option "RegistryDwords" "EnableBrightnessControl=1"
    to Device section. It shoul look similar like this:

    Code: Select all

    Section "Device"
        Identifier     "Device0"
        Driver         "nvidia"
        VendorName     "NVIDIA Corporation"
        BoardName      "GeForce GT 330M"
        Option "RegistryDwords" "EnableBrightnessControl=1"
    EndSection
  • Uncheck "Merge with existing file".
  • Save the file to /etc/X11/xorg.conf.
  • Reboot the machine and it should work.
I think it's a good idea to add this hint to your first posting of this thread.

kind regards
Christian

Hi voRia,

there's one thing left: The instructions from "Start "NVIDIA X Server Setting" from menu or type in a terminal:" to "Reboot and check if backlight control works. If so, you're done." are valid for users utilizing nVidia closed source driver only. You should add a hint and you're done. :-) Thank you!

Is there a working

easy-slow-down-manager' and 'samsung-backlight' packages

for Ubuntu 14.04 LTS Trusty?


I have the problem - with samsung-tools - that, when i decrease the backlight to strong (e.g. under 25%) then the backlight goes off completely.
And the bad point - it is not going on again when i try to increase the backlight again.

System:
Ubuntu 14.04 LTS Trusty - 32Bit
Samsung Notebook R700
NVIDIA G84M [GeForce 8600M GT] (rev a1) driver : nvidia-331 (v331.38)
