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.

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:
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!

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"
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.
[/list]
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)

I just released a new minor version (2.3.2) of Samsung Tools, in order to support most modern ubuntu versions. It's available on the (usual) repository for Ubuntu 17.10 (Artful Aardvark), and the same .deb package should also work on previous ubuntu versions (in this case you can download it manually from
https://launchpad.net/~voria/+archive/ubuntu/ppa).
Let me know if any problem!

There was a problem with localizations on version 2.3.2. New version 2.3.3 is now available on the repository that should fix the issue.
Again, let me know if any problem!

A note about power management of Samsung Tools:
Suspend, hibernate, resume and power supply events relies on pm-utils, which is now pretty much abandoned and unsupported on most modern distros. This means that most of the power management features are pretty much not functional. I suggest to use something else (like laptop-mode-tools) to handle power management.
